Coro Speedboat III
This is the original Coro Speed boat just before the first launch. I had a lot of fun scooting around with my 1.2 hp Gamefisher motor. I’ve had build plans for this for some time now. I used a 6mm thick fluted plastic sheet for the hull. A little later I added this arced decking…

Gas Motorized Kayak
I’ve owned this Gamefisher 1.2 horse power motor for a decade. I’ve used it on several boats I’ve built in the past. It only weighs 15 pounds and sips gas. It works like a dream, when it wants to. On the day I tested out this set-up, the motor was successfully started at home,…

Livingston boat ramps and dolly
Not long ago I acquired a free 9 foot 160 pound double hull fiberglass Livingston boat. Unfortunately (or fortunately) it came without a trailer or wheels to move it around once on land. My truck has an 8 foot bed, and after taking some measurements I realized the boat could fit in the bed. The boat…

Coro Speed Boat II
This was the first of my gas powered fluted plastic boats. I called it the Speed Boat. PVC was used for the Gunwales, but this proved to be a poor choice to secure an upper decking. Also the light weight 1.2 HP Gamefisher motor was used. The fluted plastic was folded for the transom, creating…

Coro box boat
For PDF plans, click here! The Coro box boat was a design that created more buoyancy than my first ‘V’ hull motor boat, the Coro Speed boat. At first the steering mimicked the Speed boat but then it went thru an evolution. On the next version a front storage area was included. A ‘V’ bar…

Coro speed boat
For PDF plans, click here! The Speed boat is basically a 4×8 ft sheet of 6mm Coroplast, better known as fluted plastic. The boat folds are similar to a Chinese to-go food box except the fluids are kept outside instead of inside. Because of these folds, all that’s needed to keep the structure together are…
