How to Stitch and Glue Boat Building-Glassing Butt Joints

Yeah, thanks for this video. Way simpler method than scarfing ply! And there is no appreciable loss of strength.

Thanks for the video, this is something that is usually glossed over in most builds, also the first time I've heard of peel ply. Also, did not realize you can do this without a backing block!!

I now live in Indonesia and don't have access to a lot of the nice stuff like peel ply and fiberglass tape. We do have some very thick tape used for insulating mufflers but it's not really useful for stitch and glue projects. Instead I use a section of ply large enough to fill the space between the ribs and or inside the seat/ buoyancy box, which works pretty well. I've also found that cheap plastic document covers work well in place of peel ply or plastic to cut down on sanding as it lays flat and is reusable. Actually I enjoy the challenges posed by not having everything easily available and have learned a lot by watching local boat builders using very simple tools to quickly create very beautiful and strong working boats from basic tools and materials. Some of these guys even have YouTube videos and I get a big laugh reading the comments from Americans trying to tell them everything they're doing wrong, which always gets a ❤️ because they can't understand English and just appreciate the comments. But these boats are out on the water and stored on the river bank or beach in a tropical climate every day without any protection. Not to mention the materials cost roughly $100 USD for a 16 footer so imho you can't argue with that.

Good morning my brother. It's great to see a good and interesting video. Great job, I love your fiber boat building video. I hope that in this difficult time, we have the same spirit in achieving success together. Good luck to you and all the best and I look forward to your next visit.

Great video I have learned something today thanks

I'm glad I found this video. I am getting ready to scarf panels for a river drift boat and was thinking of doing this method or the type of joint used by Dynamite Payson. This joint looks great and will work. Thank you.

Awesome tuturial 😎👍

Great Tutorial. Thank you for the extra knowledge and the time, the expenses and the toil I would waste building my stitch and glue plywood sailing dinghy!!!! Efcharisto (THANK YOU in Greek).-

Goodjob bos the sempl bot plywood 👍👍👍

Sar very good jobs thanks 👌👌🙏🙏

Question. My Peel ply will not come off like yours, any idea why? Epoxy resin +glass. I had a final layer of parchemin paper before placing wood and weight on top. Should I fight to get the Peel ply off or can it stay on? Thank you for a well done video.

Thanks. To anyone: if you do it with regular woven cloth tape, does the selvaged edges present a problem? Looks like Mathew is using bi-axial tape which I think is not selvaged. Thanks.

Do you ALWAYS Pre-Wet Fiber Glass Tape for every type of project? And if not, what determines your decision to NOT Pre-Wet. I'm just wondering if I should Pre-Wet like you did on my NON-Boating project (Converting Chest freezer into cold plunge)

Hmm got a question. Got some plans for a 20 foot Jon boat. It says it needs a butt and bulkhead every 4 feet. So this is the butt joint and then you use plywood and hardwood laminated together with epoxy and fiberglass atop this butt joint?

This is a evet primitive approach for seams. I am udine zipper like shapes to increase binding area and scatter momentum along the seam.

I have a new catamaran and/or trimaran hull design which has been in progress for the last 15 years. It is new/novel and therefore patentable. The hull is asymmetric. Though, for description purposes, it could be described as a variant of a conventional symmetric and a conventional asymmetric hull shape. Since, its shape is symmetrical above the waterline and asymmetrical below the waterline, the result of extending existing lines of a conventional symmetric hull at and below the waterline. This catamaran and/or trimaran hullshape is suitable for a range of craft from SAILING to small and medium POWER craft. SAILING: The hull's benefits for a sailing catamaran or trimaran are; *speed *pointing ability - VMG *no necessity for of dagger or centreboard *simple, flat panel design lines, ease of manufacture. POWER CRAFT: Benefits of an symmetrical hull shape without the negative characteristics such as; *speed of asymmetric shape *more balanced reaction to waves - less broaching *banks in turns To anyone with interest. Cheers

I am looking for plans to build a 20’ plywood skiff/dorry. Do you have a recommended supplier for boat plans?

Aloha, what kind of fiberglass tape is that? Has the joint ever come apart before the whole boat is glassed? Mahalo for posting this video!

is the "peel ply" needed? or the two ends can be joined without the use of the "peel play"?

I was taught to make 8 to 1 scarf joints in plywood to have a joint close in strength to the plywood. Is this not so anymore?
