Perfect boat, certainly big enough, certainly fast enough, good looking, rugged construction, half of the cost an Outremer. I would encourage you to talk about the Lost in Space series you liked as a boy. Upon reflection, it makes sense to me now that the show has influenced you in terms of expression and tastes from sideburns to font on the boat's name. Hope I am right. If not, forget it.
I worked in the PI from 1982-1989 and have often wondered how I could do something for the very deserving, hard working people there. Giving them jobs in building my boat just may be the answer.
Your channel deserves 100k+ subscribers. Intelligent and full of usefull information. Funny at times and never boring. I hope you guys continue cruising and vlogging. Just wanted to ask how are you going to handle the condensation on metal surfaces as everything else is well insulated, have seen in one of the episodes that the moisture almost rains down in the morning. Safe travels..
Thanks so much Bekir... That condensation was winter in Capetown with the electric blow heater running most of the time in the marina... We've never had that since.
Jamie, you have masterfully balanced content with travelogue info which I enjoy and intelligent sailing and tech tips, and DYI info that I am forever searching for in sailing videos. Thank you!! I congratulate you on your natural delivery, charm and superior editing. However, in the charm department, I am sorry to say that you are upstaged by, and you simply cannot compete with, the natural charm of your absolutely delightful Princess!
Wow, thanks for the feedback Brien... and yes, i'm aware of our USP (unique selling point)... and i'm trying to get her to do/say more... but she is shy! Cheers
Thanks Bro for this. I won’t have to shoot my own! Tim builds a high quality boat and there are elements you brought up that I had questions about and now appreciate (like access to wiring, cockpit space, etc.) Jupiter is really well thought out and the execution is top notch, a work of art that you can live in. Well done!
Simply amazingly gracious of you to share the play-by-play details of the construction of your beautiful Jupiter ( BTW Lost In Space was one of my favorite TV programs). The apparent quality and care of fabrication and construction are impressive, the trade-offs notwithstanding, to end up with a 48ft. (14.6m) aluminum sailing catamaran for $300k (USD). Of course, the question of how she handles will be answered in other videos.
@@SailingLifeonJupiter I did see your Q&A video and learned the price increase ($400k USD) still an incredible bargain. Also, adjusting expectations on time frame given the builder is very small and technically limited.
Brian the sheeting is all still fine... however some areas of the gelcoat/flowcoat coving (in the corners) has some yellowish color streaks coming through.... I'm not sure if it wasn't mixed properly or what it is... anyway, the advantages of looks and cleanability are worth it.... Cheers
Really interesting, I'm looking at a boat to take me around the world in a few years time, so looking forward to learning more. Love your sense of humour.
Carton of beer or a bottle of rum / scotch can buy a lot of work if you in the right place. I used to be into sailing many years ago. Not my cup of tea now though. I would rather be in the Australian bush. However i do enjoy watch. 👌🍻
I’ld love to understand the headroom in different parts of the boat; at the helm, in the galley, in the heads, by the berths and in the saloon. Thank you. Chris.
Bow thrusters are pointless on a cat: they serve no purpose at all when you have two engines. Even in a monohull, they are normally unnecessary. More training for the captain and crew is far cheaper and will never break down.
wow, seems like very good workmanship. i know there are some very good car builders/restorations over there. probably the same quality in the boatyards
Seems like a very good boat I will consider. Do they still build these 2023? Why are there no doors for the cabins and the toilets? The main door seems a bit odd, do you think a sliding door would be possible to fit in the space? Thanks for a great channel, I just subscribed!
Wow she is stunning,I have been searching for a cat that is the bizz and budget.Thanks,thought we were stuck with the usual suspect.I'm an Ali fan as we had an ali boat before called Tincan,just need to add a 2.
Credit to the professional technology the hull and interior finishing. I am thrilled to see this. Built a Reinke 13M (mono, aluminum) myself in 10 years and know the time involved. Did you design the interior yourself?
The only thing would be a redesigned cockpit (which is no small change)... I would prefer walk thru transoms... but then i would lose the size of the aft queen cabins.... so every thing is a compromise....
Nice boat .. Congratulations..I would like to know how the fiberglass interior was made. as the curves are made .... they were beautiful! do you have images or videos? I'm fron Brasil
What a great story, I love how the build supports the locals and also the practical aspects. How does the sacrificial anodes hold up and is there corrosion forming yet?
Thanks for watching Dollarette... The hull anodes are 6yrs old.. The prop shaft and rudder anodes last about 6mths... The only corrosion is some bubbling paint around paint chips..cosmetic only.
Is it 300k complete? Includes all blue water crushing and engines, lines rigging....etc....etc...? Can you send us the link to their internet sales site please. I wish to investigate more. Thanks
The boat is amazing, thank you so much for the videos. I have a question about security. Is there a way to lock yourself into the boat in unsafe waters?
Just watched this... again. Tossing up what to do for the next boat (current one is a NEEL 47). These are a top contender, along with a Schionning. How much work did you do on the build? It seems you were an active participant in the electronics
Very nice .. I have always been a fan of the marine aluminum hulls .. what do your divots support weight wise for a dinghy and how much solar and power storage capacity do you have now ?
Hi PO... Tim hasn't mentioned any load limit for the davits... but i'm sure there must be one.... but they are strong!.... I'm sporting 1180W of solar for a 800Ah Lifepo4 bank.... we cook on induction 90% of the time and make hot water showers with a 230v water heater tank... and unless it is cloudy for 3-5 days, we never need to run the engines (200A alts both sides). Thanks for watching
Yeah Chile... the door is on... but perhaps not obvious!... 15:52 mins the door is there, but when it is open it is locked against the bulkhead (under the window)... that's it there with the shelf with 3 holes in it... The top third of the door is removable and stows downstairs.
Great boat, ticks my boxes in so many points. One thing bugged me: aren't you uncomfortable with inaccessible wiring? I see the benefits (simplicity of producing, no chafe etc etc) still, I would feel kinda itchy knowing that one broken strand would make a branch of cables nonfunctional and there is no way to find out where or replace etc...
@@FeelItRising I was thinking the same thing on some conduit. When I built my 31' tri, I used PVC plumbing tubing for conduit in case I wanted to add systems later. I have not had any internal wiring issues since my 1993 launch but I crimped, soldered and heatshrink tubed all connections. My required wiring is also extremely simple compared to all the systems required for a big cruising cat.
Hi Jamie, I have a few questions about how some parts are finished off: Could you comment on the surfaces where the matrasses are placed. In the video, it looks like a part of the mattress simply lies on the aluminium skin of the bridge deck. Do you have any issues with condensation forming there? Are the insides of the water tanks painted? Thanks for sharing these details, your videos have been very helpful.
Hey there…yup that is the belly skin we sleep on. The Mumby is built strong, but light. Never had condensation under the mattress. Tanks welds are painted to fill any gas pinholes, but the rest is unpainted….i don’t love that my water is housed in ally, but paint would likely end up flaking off (coz ally hates paint) and causing blockages in hard to reach/clean places.
@SailingLifeonJupiter Yeah, that's ali's biggest drawback. There aren't many paints that adhere to it well. I, too, don't like the idea of potable water being stored in an ali tank. Something I'll address once I get that far... Thanks for the feedback. I'm quite surprised that you don't see any condensation under the mattresses. You have some experience sailing in cooler climates, too. I agree, the Mumby design is meant to be light.
Nice video- thanks! Assuming those are Beta engines I am curious why you did not order them from Beta Australia/Asia vs shipped from the UK? Sorry if it is a stupid question.
Can you change some of the inside layout like having a galley up rather than a galley down, have two master hulls, set it up with Ocean Volt electric engines, set up a solar arch on the transom and other things like that? What would one of these cost used if $300k USD is the brand new price? Is the spray foam a closed cell polystyrene or an open cell?
You can do all of those things.. With the right builder. Mine cost about $320 7 years ago. Now they are up around the $450-500 mark in this current crazy world... Used, they hold value very well and sell for about the same if in good condition. High demand...
@@SailingLifeonJupiter Are you expected to do any work on the boat yourself and are you allowed to help for a reduced price? How much does it cost to rent a place to stay and what does food cost per month?
In some of the drone sailing clips (like 3 boats racing), it seems that there is some fore-to-aft pitching motion. 1) Do you think this is equivalent to other designs? 2) Could it be more due to such a fine entry on the bows? I believe Catana started adding bulbs under waterline at the bows to reduce this pitching. Might that have helped reduce bows from digging in on the Atlantic crossing when the wind suddenly increased and you couldn't sock the A-Spin? 3) Are these sail drives or shaft drive from the engines? 4) Does the aluminum increase engine noise and water flow/hardware banging noises?
Yeah Steve... I think Jupiter may be a little more "active" than the other boats due to being lighter... which means we are still sailing in 5kts of breeze, and not motoring. 2. The hull entry is fine with only a little flare, so that would explain it... bulbs will certainly help that, but of course slow you down as well.... With any performance boat in a fresh breeze you need to have your wits about you...actively sailing, trimming, reefing and constant decision making.... knowing its limits and yours... and when to push it or not. 3. I've got shaft drives....most of the owners choose them so that you can beach the cat easily. 4. I don't think there's any appreciable noise level difference.... There is 1inch of spray in foam behind the interior laminate throughout all hulls and decks (except the bilges)... The loudest place on the boat is at the helm!... the noise of the wakes behind me, while we are doing 10kts.
@@SailingLifeonJupiter Being able to sail in very light air is a wonderful thing, especially for a cruising cat. It adds so much to the enjoyment to actually sail, rather than motor or drift.
I just looked up my invoice... the sheeting is 5083-H116 with marine cert... 4mm... There are also sheets of 3mm, which I guess is for less critical areas.... My understanding is that ally will crush/dent fairly readily if you take a reef... but not breach... And the dents you can just push back out again. Cheers Lucas
@@SailingLifeonJupiter 5083 is the highest strength of any of these alloys. Alloy 5083 is best known as a plate for ship building. //// In boat building, everything is a compromise. If you make it thicker, you gain weight and lose speed.
Looking forward to your episode discussing the battery bank. Interesting, how do these compare against Valence batteries? Also would be interesting to hear your thoughts on the merits of going all-electric. Two 15kW motors should be enough for a cat like this, although I'm not sure if usual go-cart motors will work in marine environment. I haven't seen any TH-camr channel with electric cat, although it makes a lot more sense on performance cats than on monohulls.
Cheers Garen.. Battery discussion is certainly on my list of todo's...there are guys planning their Mumby build right now who are keen for electric motors... But found it too expensive.
Jupiter was the name of the ship in I think but not sure. Thank you for filming this. I doubt I can ever afford something like this but it's fun to dream. Maybe when I get back to the Philippines I can look up this yard. Where is it?
@@SailingLifeonJupiter That would be a good day. Strange for me is all the islands that make up the Philippines. But, so few places to park a boat. Like marinas ... I have not found one at Dumaguete or Negros yet
Correct... I don't even know of one in Manila.... only moorings... There is very few "pleasure" sailing boats there, which makes it all the better to cruise. I think there is a marina at Olangapo (west of manila) and a tiny one in Cebu and Carmen, and Davao... they are the only ones that come to mind... I can't afford marinas anyway.... Moorings are fine, and zero damage to your topsides!
Would you be able to provide a link to the plans for your boat? One that shows the layout on all levels. This boat yard in Cebu is very intriguing as the price of your new fitted out boat is going for about the same price as a used ‘glass boat. Do any of the bulkheads going from bow to stern have watertight doors? What would the cost be for a boat equipped with two regenerating Oceanvolt drives and lithium batteries,instead of two Diesel engine-driven screws? Would still have a diesel generator for backup power and for air-conditioning.
Hey Will.. The designer /builder keeps a low profile.. No website.. But if you email me on Svjupiter2@gmail.com I'll put you in touch... No idea about the costs of electric...but there are plenty of guys considering it... Yup watertight bows and stern compartments.
I noticed the cat hobby-horse a bit in another vid where you were "racing" two other performance cats Why not double or triple the battery bank, same for solar panels, use light electric motors, and mount the heavy diesel somewhere midship as a genset, for times when the sun has been out for days, or you re motoring a long stretch, thus keeping weight off the ends, less pendulum effect btw great channel, will blow up within a year
All good ideas Monkey... and i know of some new build Mumbys coming with that plan... but having no income for 2 years now, it would be a stretch for us. Thanks for the feedback...i hope you're right!
The more I see of your Mumby 48 the more I keep thinking that I have to see one before I buy anything. I can imagine a day I'm in a three million dollar Gunboat coming back from Greenland, patches up and down the waterline and I anchor next to a Mumby. I get invited over for a look-see and it's obvious I just spent 8x the money on the wrong boat for me. They do look a bit 'old school,' in design, but just how important is that, if the modern pretty boat doesn't sail very well? (I've learned what you've stated a performance cat isn't so much about top speed as it is about sailing in light winds. What do we want a 60% sailboat or a 95% one?) Just the shaft drive alone speaks volumes. I'm coming to the realization that unprotected sail drives are great for the boat builder, but just a liability for the boat owner. I love the guys moving the mast and the ship's crane. When I was 12 my father took me to an apartment building under construction. He was the foreman. No one else was there. I guess he wanted to get a head start for Monday, so with my meager help we raised a wall at least 10 meters long, probably weighed a thousand kilos, braced it, made it plumb, nailed it in place. Same kind of thinking. What's cool about the name Jupiter, and then Saturn, etc.. planets, is there's a couple of dwarf planets one named after a Hawaiian God: Haumea, another Makemake named after a Rapa Nui God. And catamarans after all are also Polynesian.
Thanks Willn2go1... Yes I'm certainly happy to not have over spent on a boat... Not that I had a choice... But I nearly spent my dough on a crappy old ex charter cat... Thankfully I found this design.. And Tim Mumby!
It’s been 7 years or so. What would you have done differently on a Mumby? Besides the floor creaking I can’t find much wrong with this design. What’s your experience?
I'm guessing the spray in foam is just polyurethane... but im not sure actually... And no foam in the bilge... But yup, it could go cold....But not me!
Hey Marty...Nope that is something that i should've put in... in the bridgedeck it is 195cm near the doorway sloping forward to the nav table at 175 (where you sit)... Hulls are mostly 195... You would JUST fit!
I'd love to live in Cebu as my cat is being built to document the whole process. I'd even offer to help for free, welding or doing whatever needs to be done. I will be there soon!
Sorry Shawn... I'm already in trouble for the inundation ive caused Tim Mumby... I won't post his contact here... But if you're super keen email me on svjupiter2@gmail.com and i'll hook you up.
Ally is probably a cheaper material but you've got to have the skill and techniques to weld it without it warping and buckling... But with TH-cam as your instructor. . Anything is possible these days.!
Really love the design and price point. I need to find out more. Please can you send us the website and other details. This could be a cat for me also. Thanks
I'm really impressed with your cat. Like you I can't afford a million plus for a cat. Do you have a good tour video of your boat? How can I contact the builder? How long is the wait time for the build ? From watching your videos, im positive your not afraid to take Jupiter anywhere. Thanks Sid
Hey Sid thanks...yeah check out our 2nd ever video...boat tour. The build generally takes about 18-24mths... email me on svjupiter2@gmail.com and i'll put you in touch.

I think I would install two bow thrusters and use large jetski engines and pumps for main propulsion when I'm not under sail.
Bow thrusters are pointless on a cat: they serve no purpose at all when you have two engines. Even in a monohull, they are normally unnecessary. More training for the captain and crew is far cheaper and will never break down.

@@FeelItRising I was thinking the same thing on some conduit. When I built my 31' tri, I used PVC plumbing tubing for conduit in case I wanted to add systems later. I have not had any internal wiring issues since my 1993 launch but I crimped, soldered and heatshrink tubed all connections. My required wiring is also extremely simple compared to all the systems required for a big cruising cat.
The only wire in the deck head is for the light, double insulated tinned US coast guard approved
@@timmumby5348 If you are the designer of this boat you did an amazing job, the boat looks mean.
@@timmumby5348 The Mumby? no matter what, brilliant boat. I'll take two
Please keep posting!!!! 👊😎
Sure Allan.. Will do our best.
Hi Jamie, I have a few questions about how some parts are finished off:
Could you comment on the surfaces where the matrasses are placed. In the video, it looks like a part of the mattress simply lies on the aluminium skin of the bridge deck. Do you have any issues with condensation forming there?
Are the insides of the water tanks painted?
Thanks for sharing these details, your videos have been very helpful.
Hey there…yup that is the belly skin we sleep on. The Mumby is built strong, but light. Never had condensation under the mattress. Tanks welds are painted to fill any gas pinholes, but the rest is unpainted….i don’t love that my water is housed in ally, but paint would likely end up flaking off (coz ally hates paint) and causing blockages in hard to reach/clean places.
@SailingLifeonJupiter Yeah, that's ali's biggest drawback. There aren't many paints that adhere to it well. I, too, don't like the idea of potable water being stored in an ali tank. Something I'll address once I get that far...
Thanks for the feedback. I'm quite surprised that you don't see any condensation under the mattresses. You have some experience sailing in cooler climates, too.
I agree, the Mumby design is meant to be light.
Nice video- thanks! Assuming those are Beta engines I am curious why you did not order them from Beta Australia/Asia vs shipped from the UK? Sorry if it is a stupid question.
correct EN... I did order with the dealer in Hong Kong for a good price... so they we shipped directly from the UK.
Can you change some of the inside layout like having a galley up rather than a galley down, have two master hulls, set it up with Ocean Volt electric engines, set up a solar arch on the transom and other things like that? What would one of these cost used if $300k USD is the brand new price? Is the spray foam a closed cell polystyrene or an open cell?
You can do all of those things.. With the right builder. Mine cost about $320 7 years ago. Now they are up around the $450-500 mark in this current crazy world... Used, they hold value very well and sell for about the same if in good condition. High demand...
@@SailingLifeonJupiter Are you expected to do any work on the boat yourself and are you allowed to help for a reduced price? How much does it cost to rent a place to stay and what does food cost per month?
Life on Jupiter ⛵️⚓️💪
Correct! .... cheers Leather
Was he whistling "wind of change" by scorpions?
Sure was...the Filipinos love the classics.
awesome
Thanks Joseph
Love it
Cheers Evan
In some of the drone sailing clips (like 3 boats racing), it seems that there is some fore-to-aft pitching motion.
1) Do you think this is equivalent to other designs?
2) Could it be more due to such a fine entry on the bows? I believe Catana started adding bulbs under waterline at the bows to reduce this pitching. Might that have helped reduce bows from digging in on the Atlantic crossing when the wind suddenly increased and you couldn't sock the A-Spin?
3) Are these sail drives or shaft drive from the engines?
4) Does the aluminum increase engine noise and water flow/hardware banging noises?
Yeah Steve... I think Jupiter may be a little more "active" than the other boats due to being lighter... which means we are still sailing in 5kts of breeze, and not motoring.
2. The hull entry is fine with only a little flare, so that would explain it... bulbs will certainly help that, but of course slow you down as well....
With any performance boat in a fresh breeze you need to have your wits about you...actively sailing, trimming, reefing and constant decision making.... knowing its limits and yours... and when to push it or not.
3. I've got shaft drives....most of the owners choose them so that you can beach the cat easily.
4. I don't think there's any appreciable noise level difference.... There is 1inch of spray in foam behind the interior laminate throughout all hulls and decks (except the bilges)... The loudest place on the boat is at the helm!... the noise of the wakes behind me, while we are doing 10kts.
@@SailingLifeonJupiter Being able to sail in very light air is a wonderful thing, especially for a cruising cat. It adds so much to the enjoyment to actually sail, rather than motor or drift.
Great boat. What is the grade of the aluminium and how thick is the hull abouve and below the water?
4mm to keep the boat light. If it goes to a reef, however.....
I just looked up my invoice... the sheeting is 5083-H116 with marine cert... 4mm... There are also sheets of 3mm, which I guess is for less critical areas....
My understanding is that ally will crush/dent fairly readily if you take a reef... but not breach... And the dents you can just push back out again.
Cheers Lucas
@@SailingLifeonJupiter 5083 is the
highest strength of any of these alloys. Alloy 5083 is best known as a plate for ship building. //// In boat building, everything is a compromise. If you make it thicker, you gain weight and lose speed.
@@SailingLifeonJupiter Cool. Thanks for answering.
Looking forward to your episode discussing the battery bank. Interesting, how do these compare against Valence batteries? Also would be interesting to hear your thoughts on the merits of going all-electric. Two 15kW motors should be enough for a cat like this, although I'm not sure if usual go-cart motors will work in marine environment. I haven't seen any TH-camr channel with electric cat, although it makes a lot more sense on performance cats than on monohulls.
Cheers Garen.. Battery discussion is certainly on my list of todo's...there are guys planning their Mumby build right now who are keen for electric motors... But found it too expensive.
@@SailingLifeonJupiter Cheers. This channel might be of interest to you th-cam.com/users/WillProwsevideos
Jupiter was the name of the ship in I think but not sure. Thank you for filming this. I doubt I can ever afford something like this but it's fun to dream. Maybe when I get back to the Philippines I can look up this yard. Where is it?
Carmen, Cebu Mr Buzz... might see ya back there one day!
@@SailingLifeonJupiter That would be a good day. Strange for me is all the islands that make up the Philippines. But, so few places to park a boat. Like marinas ... I have not found one at Dumaguete or Negros yet
Correct... I don't even know of one in Manila.... only moorings... There is very few "pleasure" sailing boats there, which makes it all the better to cruise. I think there is a marina at Olangapo (west of manila) and a tiny one in Cebu and Carmen, and Davao... they are the only ones that come to mind...
I can't afford marinas anyway.... Moorings are fine, and zero damage to your topsides!
Aye m8’s, this is nice stuff to follow a boatbuild.
Cool Miq... But that's all I got!
I got that and I think more people than me appreciated this backstory.
Again, great video. You have history with Jupiter that someone buying used will never have. Is this Tim Mumby's shop, or someone else's?
Yup Tims yards
Would you be able to provide a link to the plans for your boat? One that shows the layout on all levels. This boat yard in Cebu is very intriguing as the price of your new fitted out boat is going for about the same price as a used ‘glass boat.
Do any of the bulkheads going from bow to stern have watertight doors? What would the cost be for a boat equipped with two regenerating Oceanvolt drives and lithium batteries,instead of two Diesel engine-driven screws? Would still have a diesel generator for backup power and for air-conditioning.
Hey Will.. The designer /builder keeps a low profile.. No website.. But if you email me on Svjupiter2@gmail.com I'll put you in touch...
No idea about the costs of electric...but there are plenty of guys considering it... Yup watertight bows and stern compartments.
Great videos!just found you channel recently I always loved "kilo" a green Mumby in Thailand around the 2002 era
Ah yes Sam... an oldie but a goldie!
I noticed the cat hobby-horse a bit in another vid where you were "racing" two other performance cats
Why not double or triple the battery bank, same for solar panels, use light electric motors, and mount the heavy diesel somewhere midship as a genset, for times when the sun has been out for days, or you re motoring a long stretch, thus keeping weight off the ends, less pendulum effect
btw great channel, will blow up within a year
All good ideas Monkey... and i know of some new build Mumbys coming with that plan... but having no income for 2 years now, it would be a stretch for us.
Thanks for the feedback...i hope you're right!
The more I see of your Mumby 48 the more I keep thinking that I have to see one before I buy anything. I can imagine a day I'm in a three million dollar Gunboat coming back from Greenland, patches up and down the waterline and I anchor next to a Mumby. I get invited over for a look-see and it's obvious I just spent 8x the money on the wrong boat for me.
They do look a bit 'old school,' in design, but just how important is that, if the modern pretty boat doesn't sail very well? (I've learned what you've stated a performance cat isn't so much about top speed as it is about sailing in light winds. What do we want a 60% sailboat or a 95% one?)
Just the shaft drive alone speaks volumes. I'm coming to the realization that unprotected sail drives are great for the boat builder, but just a liability for the boat owner.
I love the guys moving the mast and the ship's crane. When I was 12 my father took me to an apartment building under construction. He was the foreman. No one else was there. I guess he wanted to get a head start for Monday, so with my meager help we raised a wall at least 10 meters long, probably weighed a thousand kilos, braced it, made it plumb, nailed it in place. Same kind of thinking.
What's cool about the name Jupiter, and then Saturn, etc.. planets, is there's a couple of dwarf planets one named after a Hawaiian God: Haumea, another Makemake named after a Rapa Nui God. And catamarans after all are also Polynesian.
Thanks Willn2go1... Yes I'm certainly happy to not have over spent on a boat... Not that I had a choice... But I nearly spent my dough on a crappy old ex charter cat... Thankfully I found this design.. And Tim Mumby!
It’s been 7 years or so. What would you have done differently on a Mumby? Besides the floor creaking I can’t find much wrong with this design. What’s your experience?
Cool. Was that Winston lifepo4 I saw there?
Correct Kjell.... 400Ah cells... been going strong for 6 years so far
Lovely boat. What insulation did you use below the water line. As an aluminium cat, this could go into the high lats!
I'm guessing the spray in foam is just polyurethane... but im not sure actually... And no foam in the bilge... But yup, it could go cold....But not me!
Sorry if you already mentioned this, but what's the head room? I'm 193 cm tall. Thanks for the great content!
Hey Marty...Nope that is something that i should've put in... in the bridgedeck it is 195cm near the doorway sloping forward to the nav table at 175 (where you sit)... Hulls are mostly 195...
You would JUST fit!
I'd love to live in Cebu as my cat is being built to document the whole process. I'd even offer to help for free, welding or doing whatever needs to be done.
I will be there soon!
Yeah do it Evan... Are you getting one built?
@@SailingLifeonJupiter hopefully I will hear back from Tim soon. Thanks for the hookup
8:56 Someone whistling "Winds of Change" by the Scorpions.
Filipinos love their music.
Beautiful!!! Are they still producing hulls/plans? I would love to see her in fiberglass.
Don
Sure are Don... But the plans are for ally.
You will never see this boat in fiberglass. Fiberglass is too heavy to be stiff and strong enough for producing these boats.
INSPIRING VIDEO, WHAT GRADE OF ALUMINIUM WAS USED FOR THE HULL, AND WHAT THICKNESS PLEASE?
Thanks Nick... it is 5083 with marine cert and 4mm.
I recall that you get some condensation build up in your cabin - is this area not also insulated and lined with Glass? Or was it just THAT humid?
A Cape Town winter combined with a toasty blow heater with no hatches open!... Yup I guess we sweat that much...
if we want the builders info.... please post his contact info...:)
Sorry Shawn... I'm already in trouble for the inundation ive caused Tim Mumby... I won't post his contact here... But if you're super keen email me on svjupiter2@gmail.com and i'll hook you up.
Thank you, Very Nice, How is the pricing comparison to a fiberglass cat?
Ally is probably a cheaper material but you've got to have the skill and techniques to weld it without it warping and buckling... But with TH-cam as your instructor.
. Anything is possible these days.!
Really love the design and price point. I need to find out more. Please can you send us the website and other details. This could be a cat for me also. Thanks
Hey Latitude.. Yeah it's a cool design... Send me an email on Svjupiter2@gmail.com and I'll put you in touch... He has no website.
I'm really impressed with your cat. Like you I can't afford a million plus for a cat. Do you have a good tour video of your boat? How can I contact the builder? How long is the wait time for the build ?
From watching your videos, im positive your not afraid to take Jupiter anywhere.
Thanks Sid
Hey Sid thanks...yeah check out our 2nd ever video...boat tour. The build generally takes about 18-24mths... email me on svjupiter2@gmail.com and i'll put you in touch.
