It is a pleasure listening to a technical answer from someone who has obviously put a lot of thought and passion into his work. Thank you from Canada and I'm looking forward to more videos.
Fantastic!!! I know next to nothing about fiberglass and while l will probably never take on a project of this magnitude I very much enjoy learning how the process is done. As I sat and watched this video I almost forgot I was watching a video on TH-cam and not sitting in a lecture hall taking a class on boat building 201! I am going to binge watch the rest of the series, thanks for taking the time to educate me, if you ever get to Michigan, kayaking the Great Lakes, I will buy you a lager. Matt.
You are excellent at presenting, your knowledge is very good. It’s November 2020 and I am binge watching your videos, I am addicted now! Best wishes, Andy
On the contrary, your enunciation and explanation are very good. Certainly blew my understanding of "fibre glass" out of the water, and good to hear the authrorities are on top of standards relating to safety. Am watching numerically so not to miss details. Thank Doug some time too.
Great stuff buddy.I am getting to a very technical part and will need to put this stuff forward to keep you all watching and to understand my process. Cheers Rossco
Great video and I appreciate the time and efforts that you and your team have put into researching the original designs and more importantly understanding and addressing known issues that may have become apparent through service of the previous boats. The attention to detail seems top notch. I've enjoyed binge watching your channel and look forward to seeing the final boat come to life.
As i was looking for affordable cats for a long time I've never thought i could ever be able to build one, but after watching you sir i'm gonna be looking for mold .. Thank you sir for the inspiration and the detailed videos
Hey Roscoe, just a quick hello from Canada. New to your channel, trying to catch up; but would like to say I find your sharing of the above schedule's very generous of you. Mid live crisis-s so much fun Patch
Great episode Ross. I'm now wiser for the experience. I'm in the process of gearing up for a build and agonising over plan choices. Your videos are a tremendous help thank you for taking the time to document your build👍🏻🍻
Good luck Steve, I am a sponge for info as I progress through any build I hope any of this has assisted you in any way. All the best and thanks for watching.Rossco
Haha your penetrating voice is welcome! I'm very interested in these technical details and the details of the laminating schedule. Thanks for the videos! :)
Thanks for your comment, really appreciate your time to watch my series, it is a major motivator for me and love the feedback I am getting from around the globe.
Please keep making these videos! I'm thoroughly enjoying them, and will probably watch them more than once. Any notes you can make in the header on product names and sizes would be appreciated. This size project is way out of my league, but I enjoy watching someone with that much positive attitude going through setbacks, and continuing to smile!
Truly excellent. I'm catching up on all of your videos in one go - much better than a Netflix boxset. I really enjoyed the technical detail on the layup plan in this one. Using the foam sandwich to lose a ton of weight really makes sense. Possibly makes for an even more ridged hull as well, maybe? I have the plans for my 40 year old small fiberglass boat. It has basic layup detail (not a full laminating schedule) which is a real bonus when I do any repairs. Massive thumbs up from me.
All in good time buddy, that has created some issues for us, nothing insurmountable but some planning and some hard graft has yielded good results.Cheers Ross
Hey Dan, It can be a struggle to make any of this interesting, but I feel that by breaking it down I can gain a better understanding for myself as well. More than happy to put it out there to assist anyone in their endeavours.
Thanks Ross for taking the time to go over the technical stuff much appreciated I've learned loads so far. I am absolutely hooked watching this epic build progress and cant wait to see the finished boat. Inspirational mate keep it up.
Thanks for explaining the buoyancy & weight ratio issues of these mega catamarans . Vacuum bagging infusion takes a while to perfect , but extracts excess resin weight out of the layup glass , may be ideal for the FRP interior panels & parts or the upper catamaran top cap to reduce weight with the vacuum bagging infusion vinyl ester & epoxy resins. Cheers
very very interesting Ross.. it's a massive project and something I have always wondered about in terms of the design of boats and their construction. So very thankful for these videos.
Graeme, certainly a project and a half. Boat Construction is not rocket science , getting it right however can be. Takes lots of prep and a bit of boat building.Cheers Rossco
fantastic episode mate! now I've got my head around the whole boat, those glassing plans were really interesting. gotta keep watching to catch upto realtime!!
I've watched many many videos of boat building from the wooden shipwrights to home builds based off the Wharram designs. It's great to see you going into such detail and explanations of your particular process. Really enjoying the details and learning curve your presentations give. As for the penetrating voice lol. Perhaps if you purchase a Studio and spend thousands more on movie quality microphones that will even out a bit. Honestly though your doing an amazing job and so much appreciated.
I'm here not only to see a boat being built but I have a new job coming up in which I will be instructing laminators for new jobs coming through the door. I am very adapt with pre-pregs and I have done a fair few small wet layup parts in Kevlar and what not but I need to improve my knowledge of wet layup resin systems and techniques I have a fair bit to learn but your video series is helping to put technical information into a visual "this is how we use it" format thank you for taking your time with the explanations. I hope to see more great work as I continue watching.
Hey Jamie, Great to see you will be moving in to a teaching role and getting more people skilled up. It a sad fact that we are losing these skills and cheapening product in an insatiable demand for low quality. I love the whole composites industry and have seen some incredible work over the years but believe that by sharing this stuff I can assist others to go ahead and tackle some pretty inspirational projects rather trading it away and undermining our futures. Good luck and I appreciate your comments . All the best Rossco.
I like the sailing videos. I like the channels that focus on the travel, the experiences, the food, the people - all that stuff. As someone learning with my wife to double hand, sail, get certifications, with the intent of chartering a lot of different boats in different locations in prep for (hopefully) early retirement - I really like tech videos. Mechanicals, refits, repair, 12/24V systems - all that stuff. This is the first series I have watched like this - and I have to say, this reboot to explain the schedules, diagrams, etc. was superb. I have learned more about fiberglass boat and cat construction in the 4 days since I found your channel than any articles I've ever read. Well done, and explained. Also interesting to see about the foam core discussion - as I understand it, Discovery uses foam core to the WL for insulation, weight decrease and strength. I'm not familiar with the foam itself to understand the strength part (your I-Beam comparison was great), but I can certainly understand the insulation and weight parts. I'm looking forward to seeing the videos of the insulation laid up. Much appreciated! Cheers.
So great to hear you are getting some value out of my series.It is a time consuming effort to produce, but primarliy for my benefit but has certainly struck a chord with some viewers. Enjoy the ride.Rossco
Thanks a lot again man!!This video is very informational, I think i have decided what I am going to do with my Cat hull. Just got to work out a design for it.
I have been following you since the beginning I am planing on building a trawler yacht from scratch (my own design). You have given me so much to think about, as I am currently planing on sailing my own boat. However should I chose to have this go to production, I must follow some more rules as to Glass lay-up schedules for Canadian Maritime safety Standards. This particular video has been getting a lot of re-views from me, lol. Love the series may you and yours have a great new years, looking forward to more.
+Schpankme Verimuch Totally agree.The Vinylester has most of the attributes of epoxy with with the workability of polyester.As well as the reduced cost.Thanks for watching. Lots more to come.
Dick, It is often overlooked in the composites world but is a modified epoxy with brilliant corrosion resistance and excellent UV stability and protection so is ideal for boats that see a lot of sun and heat. and off course is compatible with polyester gel coats and finishes so is very easy to work with. Gel time can be tricky with certain humidities but can be a real winner in the right application.
Very good explanation, Thanks. Glad the Skincoat is done. As you move about by foot it will help when its time to pull the structure. Wondering if you used PVA and maybe installed some Air Ports (1/4 inch flush) to help pop her loose. (Smile) . Very interesting watching you. Agree that vinylester is the way to go. No blisters forever. That’s all we use in California these days with the Restrictions on Styrene by Air Quality Management.
Skin coat was down in a day, Took the pressure off somewhat. Didn't PVA, the hull,it had 2 coast of sealer glaze and 4 waxes with TR Release agent, but definitely have about 20 strategically placed HP air ports positioned in corners, bridge deck, and below the waterline. Hull has pre released in a lot of places where I have been using a vibrating roller on foam core and along the gunwales so am confident it wont take too much with a gently lift from a crane to lift her out. What I can see down the gunwale sides is very promising. Vinylester is so much easier to work with and has the added UV Stability which is vital for here in Aus Stay tuned and appreciate the comments. Rossco
Great explanation and episode. Why is it that the first 3 layers do not protect against osmosis on their own? I wouldn't have thought after gelcoat and 3 layers the rest of the layers would simply be for strength and not provide any other benefit. Note: I have no experience with composites. Looking forward to watching the rest of the series!
Ahh. This is TH-cam at it's best! Is there major difference of bonding of vinyl ester and epoxy if you're doing wood structures? And does it cure without sealing? (I'm in knowledge that polyester needs to be protected from oxygen to cure completely...?) How about UV-resistance?
Hey buddy. Vinylester is suited to wood sealing and will bond to anything including polyester so you can move from one poly to vinyl without any further prep, however it exhibits superior UV capabilities than epoxy especially in exposed areas. Laminating polyester, like gel coat will need a wax in styrene added to it to ensure the wax rises to the surface as in Flow Coat, and will then fully cure. Vinylester based laminating resins will cure in 48 hours so will require sanding and a reactivation wipe with styrene to be able to to ensure a chemical bond. Glad you are enjoying my take on the process. All the best. Ross
Love your series Ross, good on ya. A few questions. What's the advantage or disadvantage to using epoxy resin in place of vinalester? Second, does your foam core have stringent requirements for strength properties? Cheers!
Thanks for the comment Bill.Vinylester Resin offers a similar backbone chemically to epoxy, ands is in fact a modified epoxy but requires styrene as the carrier.Advantage is cost basically around 2/3rds of the price of epoxy and I have found a lot easier to work with and not so dependant on humidity and temperature although you have to be careful when working with it that you don't exceed catalyst and humidity levels of 75% or greater.Another benefit of Vinyl Ester is that it has a UV inhibitor in it as surfaces made of epoxy are likely to suffer from yellowing and brittleness over time, although epoxy is stronger in its raw form and has an element of structural strength in itself as Polyester and Vinyl do not they rely purely on the reinforcement for this strength. Vinylester is also available in different grades and is manufactured differently from season to season according to gel times, ie Winter and summer grade with varying gel times to allow for working time in lower and higher temps. The Foam core has a structural guideline that is rated by Lloyds of London for Insurance etc purposes and carries very strict ratings that can be purchased in a range of different grades and thicknesses and foam quality.A link is here to the foam core I have used , it makes for interesting reading. www.gurit.com/Our-Business/Composite-Materials/Structural-Core-Materials All the best and great to hear from you. Rossco
Your plans were predicated on the foam being used in specific places in the hull build, so when you had to remove some of it to install the modules will that have an impact on the certification?
Gidday Lance , I have 80cm on the bow and 60cm under the bridge deck in the midship which is higher than most ., I have a nacelle mould also for a nacelle that I will likely install to break up and vaporise and dampen the slamming. I wil probably change it to have further chines to increase dampening effect I don't envisage massive speeds but the solid bridge deck has now been lightened with foam bulkheads and crash compartments to reduce the issue further. Ross
Thanks Pete, You will be happy to hear I have ordered one. Not sure how I will be able to use it with all of the safety crap I have to wear to stay safe, it's like a NASA mission every time I go into laminate, but I will make sure I can use it when I can, definately not a video editing specialist and cause I am not 18 I
You actually don't have such a bad instructional voice. What does piss me off. I'm only around 10 in at the moment. Another 30, 40ish to go.....I'm actually enjoying it
i dont understand y u have to do what the plan tells u to do there was a man who designed a bridge going acros the river thames in london and when the workers looked at the plans they said the bridge will shake when people started to walk on it but he said it wont just build it to the plans spec yesssssss u no it the bridge started to shake designers dont no nothink
I've got an idea. Why don't I stand in front of a video camera, and say alot of stuff, and in the background have a lot of bizarre and meaningless drawings? I bet that will make a good video, and impress the hell out of people.
It is a pleasure listening to a technical answer from someone who has obviously put a lot of thought and passion into his work. Thank you from Canada and I'm looking forward to more videos.
Fantastic instructional video. Its very rare to find such material on the net. Thanks

Thsnks for your compliment great to
see people enjoying the content.Ross
Great explanation on how it will be laid up
Your voice is not a problem at all! Thank you for that simple and clear explanation of resins and layup.
Finally someone explaining the foam core lamination and the joints. Very interesting. Would you share the .pdf ?
Great explanation on what a lay up schedule is, and the strength it provides to the hull. Very easy to understand and follow. Thanks for the series!!!
I started with 1 video, bugger I'm hooked
Sorry Allan,we are gonna be good friends by the end of this you know.Cheers Ross
You are excellent at presenting, your knowledge is very good. It’s November 2020 and I am binge watching your videos, I am addicted now! Best wishes, Andy
Gidday Andy.Welcome aboard.You have a big job ahead of you and look forward to hearing from you.Cheers Ross

Excellent Mike,it is a work in progress and my vids try to flow in a chronological order so as to show the process.Thanks again.
Love these tech talks

Wow, what a great video. Would never have guessed how complicated this all is -great explanation, could have listened to that for hours. 👍
Good stuff.Glad you got something put of it.
GREAT TEACHING!!!!

Great info. Thanks for taking the time to run through all this. I can't wait to see how you fit the foam.
All in good time buddy, that has created some issues for us, nothing insurmountable but some planning and some hard graft has yielded good results.Cheers Ross
Thanks, Ross. You make this stuff interesting. I appreciate you sharing all of this.
Hey Dan, It can be a struggle to make any of this interesting, but I feel that by breaking it down I can gain a better understanding for myself as well. More than happy to put it out there to assist anyone in their endeavours.

Cool Trane.All good fun.
Your voice is fine. I have no issue with it. As an Civil Engineer, this stuff is fascinating.
I BOW TO YOU SIR! A real pleasure to see you at work and listen to your explanations and demonstration of experience and dedication. God Bless.
Thanks so much for your comment, it makes all of the editing worthwhile to receive such great feedback. All the best Rossco
Didn't even know about vinylester resins. Learned something already!!!
That is excellent, I appreciate your comment. Cheers Ross.

Nick, I am all about the behind the scenes, [lenty of that going on here. Getting some great sympathy out there. Cheers Ross
Amazing video. Thanks for all the detail love your understanding and obvious commitment to quality in the boat you are building.
Thanks Mick.Glad you got something out of it.Ross

A very instructive and well-done talk. Thank You!
Thanks Rayglad you enjoyed it more fun to come.
good job
Binging on your vids- I think the info and presentation is great! Thanks!
Thanks a lot again man!!This video is very informational, I think i have decided what I am going to do with my Cat hull. Just got to work out a design for it.
Hi Ross i have worked with fiberglass over plywood but i have never done it in a mold so i'm learning a ton thx for the education
Thats awesome Mark,really appreciate you watching buddy.All the best ,Ross

Very good explanation, Thanks. Glad the Skincoat is done. As you move about by foot it will help when its time to pull the structure.
Wondering if you used PVA and maybe installed some Air Ports (1/4 inch flush) to help pop her loose. (Smile) .
Very interesting watching you. Agree that vinylester is the way to go. No blisters forever. That’s all we use in California these days with the
Restrictions on Styrene by Air Quality Management.

All the best and great to hear from you. Rossco
Your plans were predicated on the foam being used in specific places in the hull build, so when you had to remove some of it to install the modules will that have an impact on the certification?
where can download the detail drawing planning to built one
Nice1 for the detail :)
Is there a waiting list to take a turn as a deck hand?
Build two, sell one to pay your expenses.....lol. Thanks for the video.
Hello. Is it possible to get a plan from you? thank you in advance
Great video! How high is the bridge deck from the water line?
Gidday Lance , I have 80cm on the bow and 60cm under the bridge deck in the midship which is higher than most ., I have a nacelle mould also for a nacelle that I will likely install to break up and vaporise and dampen the slamming. I wil probably change it to have further chines to increase dampening effect I don't envisage massive speeds but the solid bridge deck has now been lightened with foam bulkheads and crash compartments to reduce the issue further. Ross
Cheers for the reply. That's good clearance. I think adding the nacelle with chines is a smart idea.
dark age laminate why are you not using infusion?
Hola subtítulos en español .......!!!!!!
Excellent vids but please please please invest in a microphone!
Thanks Pete, You will be happy to hear I have ordered one. Not sure how I will be able to use it with all of the safety crap I have to wear to stay safe, it's like a NASA mission every time I go into laminate, but I will make sure I can use it when I can, definately not a video editing specialist and cause I am not 18 I
You actually don't have such a bad instructional voice.
What does piss me off. I'm only around 10 in at the moment. Another 30, 40ish to go.....I'm actually enjoying it
Looks like you have some catching up to do,sorry this could take a while.Cheers
