EPISODE 24
Alan's underside has a number of old lifeboat fittings sat through the hull. They are a risk in icy seas, so here I set about sealing and protecting them.
Products mentioned:
Composites release film
Epoxy laminating resin (slow cure)
200gsm plain weave fibre glass (glass fibre) fabric
Model: NME A/S (Husnes, Norway) 7.5m TELB
Engine: Bukh DV48 turbo diesel

🤣🤣🤣
The "Alan!" in the establishing shot made my day
A golden moment.
Alan! Twas I.
Planck, because the use of the sleeping platform is constant.
I don’t think anyone got your clever response.
Mr Sadman or Morpheus's elbow could work as a name for the plank.
Love Alan and love your videos!
Cheers!
I suggest a plate to cover the keel cooling pipes. Protective but not fully encapsulating so as not to effect function. I think a fitted plate running for and aft would create less drag than a cage.
Great work, both Alan and the documentation.
Thanks for the input
Each time I here it's cald Alan I think about the short video with the ground hog. "Alan! Alan! Alan!"
Nooo! I have reached the end of the Playlist! No more binge watching 😔
You're better off with keel cooling in ice conditions because water intakes can get clogged with ice. Consider putting an arrow shaped wedge in front of the keel cooler to deflect debris to the sides and eliminate the blunt forward edge.
Certainly an option in my box of ideas. Will expand this later into a full consultation.
I’m enjoying this series, I don’t mind 3d printing random odds and sods like this if you need it
Cheers!
Just discovered your channel, binge-ing this weekend.
My first thought about that cover is that it's very clunky and would pound into any ice it encounters. If it flared out and were gently sloped in the primary direction of attack, it would nudge the ice away instead of hammering into it.
And I fully admit that I have zero knowledge to back up this post. Soooo...
And, I have zero use for any of this information, but it's really interesting and well presented. Thanks for it.
Bye.
Cheers Bill. Hopefully the design will become clear in a future vid.
Thanks for using my footage mate, that was a nice surprise! Great video as always. Plankety Plank. Or can you name it Tom after me?! 🤣
Thanks for letting me use it!
Knew it was you instantly... You are a Legend among men sir.
@@createdezign1840 bit of a shock, despite roughly knowing already where Alan is! He was so majestic in the morning sun!
The longer this series goes on the more I want to get my own Alan to build, for.. absolutely no purpose at all.
Do it - I am ...
Same dude
And of course, if you’re going down the HD2 route, you could call it the Sleeper
I like this, but it lacks the satirical sting....
just found the series from recommendation and couldn't stop watching! cant wait to see where it all goes... thank you for all your hard work, bringing informative content, in a very humorous way.. well done!
Cheers and welcome!
I think Berth-a would suit Alan!
Just what I needed after a long day. Thanks!
It will be a stronger plug if you remove the stainless fittings and fiberglass the holes that will keep everything flush with the hull!
My concern with that is I have no idea about how deep the steel is set into the hull, and how it's bedded. If I kept grinding back the metal, I could end up with a real mess, and would then have to grind back surrounding fibreglass and completely rebuild the structure with new fibreglass. This method is less complicated and is belt and braces - I'll comprehensively seal from the inside via the through hull fitting, and then fibreglass on this cap, which will only end up slightly proud of the surface.
@@AlexHibbertOriginals unscrew the throuhull and the stainless should be able to be removed
Run out of videos. RUN OUT OF VIDEOS!! Great series, enjoying this immensely. Can't wait for more. I really want my own Alan now...
Thanks Dave. More in Sept.
Congratulations!! You have me totally hooked on your Alan video's.
I've even bought myself an Alan cap... I promise to take a look at your non Alan related videos soon..
Cheers, Chris
Thanks Chris
The super Sleek Sleeping Slab
I'd suggest just naming the plank "Matt Damon"
Yay! New episode! And the angle grinder returns!
Having thoroughly alienated crew, family and friends, Alex performed the minor refitting modifications necessary for a lunar expedition. Strapping on the sufficient quantity of explosives to achieve orbit, Alex then launched himself and Alan into space.
Your creation of the shallow dish gave me two ideas, why not use a small bowl, or even a balloon and cut out multiple covers from one piece of fiberglass.
I had a good look for a suitable bowl, but none I could find had the right angle and size.
You could reference the scientific aspects of the expedition by calling it Planck
This has legs.
Make a shroud for those cooling lines from perhaps aluminum treadplate.
Really Nice
For the sleeping platform could be appendix or wisdom tooth as both are fine to have till they become a problem
Still want one!
look for flash breaker tape to protect the gellcoat while sanding on or neer it. comes in .005 and .002 thick
AMAZINGNES!!!
Why not call the bunk "the water board"?
Just wondering, I rarely use Amazon, but if I did and wanted to buy one of your books for free shipping, which would you recommend Alex? Thanks!
Awesome
Maybe I missed the point of the dome, but what is the point of the dome?
If I understand it correctly you will attach the dome above the thing you just cut off?
Why not just make that thing flush with the hull instead of adding a protrusion?
And if there's a protrusion, why not include the wood mold? At worst, it rots and you end up with the same strength as if it didn't exist.

@@AlexHibbertOriginals I guess that makes sense.
Even though you said in the video that you made the dome deliberately oversize to cut it down later, I still had the image of that huge dome sticking out of Alan's hull in my mind :)
I guess it won't be as big of a bump as I think it will be.
Will cups be stealing more scenes in this series?
I will admit for a moment before anxiously trying to will the cup out of the shot, I enjoyed a fair bit of suspense as I wondered what trick you were going to reveal with the mold.
You wouldn't believe the sort of head-scratching that went on in the edit suite once I realised I'd done that. Believe me, the original cut was even more hopeless!
I think it’s possible to build a cage to protect the keel cooler. You’re not going that fast after all and the your centerline keel does offer protection as well.
If you do plan to discard the keel cooler then you could possibly use one of those through drains that you just cut the cage off of as your raw water intake.
Some things to consider about switching your cooling system style. Are you still planning to keep Alan for more then one trip? If so then when you change from keel cooling to raw water cooling it’ll require some additional conversion. You’ll need a heat exchanger. You’ll need a belt driven raw water pump (jabsco) to draw raw seawater and pump it through the heat exchanger. You’ll need a sea strainer to strain/filter the sea water. Unless Alan is only going to be used for a one way journey. Because if you pump sea water directly through the engine then engine life will be extremely limited.
Alternatively you could switch to a more robust plate style keel cooler. Rather then the pipes. Similar to how a narrowboat keel cooler is. Obviously it’s different as Alan is fiberglass. But you could build a long, slender, thick steel tank the has sloped ends and it made from thick steel to resistance ice damage. This tank style cooler could utilize the same through hull holes as your current keel cooler pipes going.
However if you do abandon the keel cooler then you can build up a little fiber glass or thickened epoxy around those through hull plates. To make it a smooth transition across the plate so that ice can’t catch.
Your thought process is similar to the conversations I've been having. Will update!
(I'd never run raw seawater through the engine)
@@AlexHibbertOriginals it sounds like you’ve got a solid plan forming. I look forward to hearing it at your convenience.
Seriously nice work so far!
My thoughts and advice are put forward with respect and meant to be helpful. I hope I’m not coming off as a troll.
Cheers,
Jeremy K
Keel cooling will always be superior. If it were me, I might make some custom fiberglass bumps round it for protection.... in the very least, the front. Of course, you could always make the other system you mentioned to work in tandem or as a secondary system for redundancy since if that fails, it’s not the type of thing that’s easy or really possible to fix in ice water.
I'm mulling this very seriously.👍
@@AlexHibbertOriginals Cool. Cant wait to see which direction you decide to go. New to the series but I binged it to catch up.
1:00 You should have worn ear plugs. I SAID, YOU SHOULD HAVE WORN EAR PLUGS !
HALF PAST TWO!
Will you reinforce Allen's lower bow as it will encounter ice and some of it can be sharp. Basically you need armor up the front.
There are many ways that ice can stress a boat hull: sharp point impact, crushing from both sides, scraping, and a blunt collision.
Glass fibre is good at handling some of this. Energy can dissipate through the flexing of the hull pretty well - better than metal - and steel hulls only win in this sense through sheer bulk, if thick enough.
It's important to avoid crushing either by lifting up out of the ice pack, or through lots of bracing. The former is preferable.
Impacts will have speed as a factor, and it's notable a closing speed will never exceed 7 knots with Alan.
Given all this, something I will consider is a bow-mounted structure to divert ice along the sides. Ultimately, it's boat handling that will avoid a head-on collision, full speed, with a 1000-tonne solid ice pan.
just found this channel, can anyone explain to me what he’s planning for? is he gonna love in this boat? is he gonna take it exploring or something?
He's going to go to the artic with it.
"Alaaaaaaaan!"
No advertisement, except from a shameless book plug
Indeed - to try and add it in slyly would be unforgivable.
Hello alex i would recomend Concrete "diamond" grinding disc they work on everything and will last LOOOONG time than any grinding disc. Thank me after you've tried one ;)
I'll check them out. This zirconium flap wheel is going strong after quite a few months though.
@@AlexHibbertOriginals i get that but with that one you can cut through annything haha it has such agressive but soft ttouch too
Any chance you’re books are in audiobook form?
Not anytime soon I'm afraid.
A 3D printer is such a device, you never knew you needed it, until you have one.
You should get a 3D printer! You can get a very solid one like the Creality CR6 SE, and be up and running within weeks of troubleshooting and waiting on 14-hour prints that fail in the last 20 minutes. Only a few dozen kilograms of filament wasted on failed test prints and you'd have that dome shape knocked out perfectly, once you figure out the ass-backwards software required to model for accurate dimensions!
Just kidding, obviously. Even if you had a buddy with a 3D printer who could get the model done and the print started within 20 minutes, you'd be done with your entire process including mounting the final end result by the time it was done printing. I love my 3D printer, but damn does it take a long time to do even the simplest things with it.
The form/mold you are using for the fiberglass dome work would be called a buck if used in vacuum forming, not sure if it's the same in your application.
Just what we need - another name for the block of wood.
- in an artic enviroment heating your hull might be a good idea. How would you get the boat out of the water when on expedition?
I'm unsure what you mean about heating the hull?
The boat can be rolled/winched onto ice pans.
Alex Hibbert Originals - you are in an environment where icing on the boat is a possibility. How do you get the ice off? Heat or isopropal alcohol?
I think generally you manually de-ice any areas that are being affected. But Alan will mostly be stationary during the coldest conditions.
Alex Hibbert Originals - by stationary, you mean pulled up on the ice?
How does frozen fibreglass react to having the ice hammered off? Take a tent you can prop up on the hull, and heat.
I am bringing this up because visions of the Franklin expedition keep coming to me.
How will the fibreglass hull fair against chunks of sea ice?
It's all at low speed. Most will just roll down the sides. The dramas to avoid are a blunt bow-on impact against a large pan, or ice getting pulled through the prop guard.
Having worked in fibreglass repairs, that is the strangest way of removing a skin fitting and hole that I have ever seen...
I aim to surprise!
How about Bunky or Noddy 😎
The dome needs to be thinner or your as likely to knock it I personally think!!!😋
The pattern is very oversized compared to the part that will be used from it.
Max (as in M Planck Institute)
i'd be happy to do some 3d printing if you require 👍
Very kind!
Alan the adolescent after all he will soon have pimples.
Ian the Plank...
you should put everything back or it might not be seaworthy!
What a strange thing to say.
@@AlexHibbertOriginals I love you.
call it fluffy
Do what ever you want to do , don't care about the bunch of Sisis always complain.
Bunky McBunkface, of course.
It's namesake is too on-spec and on-budget.
You can’t get out air bobbles using a brush. No way .you need a steel roller and some experiance in building glassfiber boats. Just saying beeing a fiberglassboat builder for 30 years now. Otherways GREAT WORK!
For this small part, I do have to beg to differ. The laminate, before I placed it over the pattern, was easy to check due to the translucent glass, and it was bubble-free.
Planky mc plank face
Damn, you beat me to it.
Clearly his name should be buck
Why didn't you just us a shallow plastic bowl for the mold?
I looked, but none were shallow enough,
@@AlexHibbertOriginals I figured that might have been it.
Plankton.
Name the Birth...SWOEO.(pronunciation differs). Sleep with one eye open, you might wake up in the bilge.
The sleeping platform costs more than it’s worth, is unnecessarily heavy, and is apparently not capable of much. There is only one truly apropos name… America…
No political jokes, well there goes my idea of Mattress Planking system or MPs for short...
Id u don't have a 3d printer, you can outsource the printing www.hubs.com/3d-printing/
Shit the bed. It's a bed but it's shit.
Please hear me out. Lose the engine and fuel tank. Replace it with an electric motor. Solar panels. More batteries. Add some little wind turbines (at least 2). Add some mounting for detachable masts (in case you'll need to sail if engine broke).
You would have saved more space and gained more speed. 6 knots ain't gonna cut it on stormy seas.
Solar and a couple of wind generators won't generate enough power to run c.40hp electric motors without long periods sat inactive, charging up.
6 knots is all the boat will do in any configuration. In difficult seas the limiting factor is going to be the thrust the prop can generate. It appears from sea trials that the prop is relatively high thrust (despite only three blades) since the hull's max speed is achieved at fairly low engine revs.
I watched on another guy's channel that he can run 18 knots on his full solar yacht.. Can't remember the name now
Alan would have space to install perhaps 4-5kW of solar and wind generation, at a push. Just not a go-er without a diesel generator, sadly.
Solar panels? In the arctic? Where the two options are no sun and very low sun (and clouds)? Supplying 700,000 watts per day for 40HP?
Bye
I don't like "PLANK"
I much prefer "The Plank", "Mr Plank" or "Miss Plank" as correct capitalisation is as important as using the correct pronouns.
I don't care what you call it, but whenever I see it I will think of it as "Mr Plank". I will correct the pronoun later if needed.
