How to Make a Plywood Boat

I spent about a month on this project and it was fun overall and worked like a charm. I suggest you to build this. it is fun when it is complete and the cost was about 500$. used a bunch of stuff for this project including 2 sheets of plywood, wood scrap, pvc piping, marine safe paint, wood screws, flex seal and epoxy

Step 1: Cutting and Measurements

First I needed to cut the plywood out using plans off the web. I used plans of a website called hvartial.kapsi.fi. after I got my measurements I cut out the wood to the right size.

Step 2: Attaching All Sides

After all the pieces were cut out I use a piece of would about 1 inch by 1 inch and about a foot long and screwed in both sides to it from the bow. then I attached the stern using the same method as before. I used wood glue and screws. after everything was screwed in i use a piece of wood 1 inch by 2 inch about 2 feet long to put into he middle to expand the width of the boat.

Step 3: Attaching the Bottom

Then I cut out a rough depiction of the bottom screwed it into the the posts that I put in close to the bottom about 1 inch by two inch's and four feet long. after the bottom was securely attached i use a jigsaw to cut the excess wood that was left from the rough outline.

Step 4: Finishing Touches

I then added custom seats to the boat flex sealed the outside and bottom also using epoxy . I attached a gunwale as well as transom on the stern for a small engine. after I felt like all the wood working was complete I got black and white marine paint and painted the inside white and the out black and white with a stripe. than I finished the waterproofing with a few coats of polyurethane. after I finished painting i added two rods holders for fishing using pvc piping I had laying around

Step 5: Final Product

After a month of hard work me and friends managed to make a fully functional plywood dingy that has a motor and everything you need for safe travels on the water.

Did you use marine plywood?

[adolfothebuilder]

I didn’t use marine plywood because at the time of this project I was getting all my materials at Home Depot but it doesn’t really make a difference as long as you cover the plywood in waterproof paint or sealant

The measurements for the side piece do not seem right and it shows on my tablet as a 0 second video. Could you please confirm the side piece measurements. Looks great and I would love to see more views of the outside paintwork.

[adolfothebuilder]

The measurements are all correct I don’t know why the website made the picture a video. The reason it looks wrong is because the three measurements in the middle are the post you put in to expand the boats diameter and the rest are just a little complex. If you have any more questions ask me.

I will also get more pictures of the paint job and engine that I got in the post

The smartest thing I see there is a coat of polyurethane over the epoxy. Epoxy breaks down to a dust in sunlight whereas polyurethane does not .

Thanks for the feedback!
