Powerboats

Flat iron skiffs are said to be easy to draw but very hard to get right. QT is my attempt at a flat iron skiff. The prototype was built by Paul Krayniak of Odessa, NY and a photo of his boat is presented below. The above photo is of Brad Boerger's QT. I...

Poor Jon20, he's just a big dumb jonboat. 20 feet long and 6' wide on the bottom, 7.5' wide on the top. It takes a ton to set it 4" down in the water, and I expect the empty hull might weigh 600 pounds. So let's say she weighs about a half ton with a...

BRUCESBOAT, POWER SKIFF, 19' X 5', 250 POUNDS EMPTY Bruce was looking for a large powered canoe but couldn't find one for sale. He said they still make them by hand in Maine but he was in California and you couldn't expect to buy one anyway unless you...

AF4 is a simple low powered cuddy cruiser intended for protected waters. Kilburn Adams of St. Louis brought a boat similar in spirit to AF4 to our Midwest Messabouts and it was easy to see what a good idea this is. Kiburn's boat was a modified Sturdee...

Dani Jay is the chosen name of the project I called Bobsboat in last year's essays. The idea behind it was to have an easily driven seaworthy launch that would take a bunch of adults around in a laid back style. It was not to be a planing boat so big...

Af4 Grande is a 20% scaleup of the original AF4. Scaling a design can be interesting. If the design is scaled up by a factor of1.2 as it was here then the areas of all the panels are increased by a factor of 1.2 squared (1.2 times 1.2) which is 1.44...

Jonsboat is just a jonboat. But where I live that says a lot because most of the boats around here are jonboats and for a good reason. These things will float on dew if the motor is up. This one shows 640 pounds displacement with only 3" of draft. That...

"Dear Jim, I've got to tell you - that little AF4b of yours is a marvel.I've logged close to a thousand miles on her so far, through streams,rivers, canals, bays, sounds, and even one unplanned foray intothe wide Atlantic*; in blazing sunshine, driving...

Electron was an interesting project done for a man who had done his homework on electric boats. In particular he had studied Doug Little's great book ELECTRIC BOATS. He wanted a cuddy cabin boat capable of some cruising, the ability to go about 30 miles...

Campjon is based on my Jonsboat design. I increased the hull depth to 24" from 18" and again to 30" in the region of the 6' long cuddy cabin. The cabin decks slope upward towards the center so the "headroom" in the middle is about 3', usually that is...

Jon Jr. is a small jonboat, sort of a personal sized boat that will take two normal sized adults. It would be a perfect "back of the pickup truck" boat. It could be cartopped. (To me the idea of cartopping a powerboat is a bit strained since you would...
