Intro: Plywood Boat
This is a remake of an idea that I saw at a friend's house. The best part about it is that it only used a single sheet of plywood and some wood screws. This is a fairly easy build to do in about a week because of the dry time for the caulking.
Step 1: Tools and Materials
For this project, I used the following materials:
1 - 4x8 ft. sheet of Southern Pine 15/32 inch Plywood.
30 - titanium wood screws.
2 - tubes of 5.1 oz caulking.
I also used the following tools:
- Drill with a 1/8 inch bit.
- Medium-sized phillips head screwdriver.
- Carpenter Square
Step 2: Cutting the Pieces
I took the 4x8 foot sheet of plywood and made the following cuts:
1 - 2 ft. x 96 inch piece which in turn is cut into 3 smaller pieces:
1 - 18 x 24 inch piece for the bow.
1 - 66 x 12 inch piece for the bottom.
1 - 12x24 inch piece for the stern.
2 - 12 x 96 inch pieces for the sides, which were later cut to form the angle of the bow.
I used a jigsaw for the minor cuts of the 24 x 96 inch piece, but had Home Depot take care of the major cuts.
I would recommend having your local store just make all the cuts, because the ones I made are a bit sloppy.
Step 3: Putting the Pieces Together
To connect the pieces, I used titanium wood screws to secure the bottom and sides.
First, I connected the stern to the bottom with 4 screws.
Secondly, I screwed the left side to the bottom and the stern.
I then connected the right side to the bottom and the stern.
I finally screwed the bow at an angle of about 35-45 degrees to both of the sides.
Lastly, I caulked the living heck out of the entire thing, so when you float it, it doesn't fill with water and sink.
Step 4: Making the Seats
I used some of my left over wood to make a seat for myself. It's not the comfiest thing the world, but if does its job nicely.
To do this I cut out a piece from the side that was 12x10 inches. I also used 2 pieces as the stool legs that were 2 1/2 inches wide and 9 inches long.
Step 5: Painting the Hull
I would use marine paint, which you can buy from your local hardware store. Make sure it is for wood. This is very important because wood tends to absorb water and it will rot if it is not protected.
Step 6: Summary
In reality, the math showed me that I could fit 350 pounds in this little boat, including a small trolling motor and battery. This was a pretty easy project for me, and I would especially recommend it for aspiring DIYer's. Overall, this took me about 6 hours to make, not including dry time.
