Looks like an Uffa Fox design, that shape was his signature. I used to have a Jet 14 that was his design. Great fast boat.

What may not be clear in the hot molding video, is that the wood is coated with glue and allowed to dry. Then after assembly the steam heat and pressure activates the glue
This is the British book that turned me on to cold molding. Probably read it 20 times over the years when a teenager..

Thank You
I signed up but it wasn't having me yet. I will be persistent.

Awesome video. I hope those guys were working on piece rates; they were hustling.

That is a really cool rescue story. How you builders have saved some classics is very cool.
I love where the builder says " even if I have to throw it away, I will know how it was built".
I envy the talent on this thread.

Default Boat Building Kept me from Being Incacerated Like the Rest of my Friends.

Kids can do much more than play on a device.

Default 17' River Boat





Guys, I have started working on a 17' boat that my dad and I are planning to build for the river. After reading through this thread I am pretty sure I have a bottom issue much like the one on the 17' ENVI boats that were discussed. Based on what I read, I will need to correct my bottom so that the chine doesn't start turning towards centerline immediately as it does now (more like the red line in the last picture). Any other feed back would be much appreciated before we start building.

For whatever reason my profile shot did not get included in my previous post.

that's weird. before I read your post, just looking at the pics, I thought, hmm reminds me of the gcc/envi thread. But looks to my very untrained eye, to have sufficiently whetted surface area (from the bottom view).

I look forward to the comments.

btw-is there no software that can predict a designs real world performance characteristics virtually?

There are software suites that can do that but most are priced just slightly above the atmosphere and require some serious computing power to run. Far above even today's best desktop computer as good as they are.

I run the Nautilus package Pro Surf 3 which has come down a lot on cost since I bought my copy. It's good for the basics like static loading and stability but for the big jobs I pass it off to he folks at Donald Blount and associates. They do the full Monty and run the speed, ride and even vertical acceleration prediction (when running in various sea states). So far they have nailed it every time!

It's not exactly an inexpensive path bupawhen you're building a new design it's very reassuring to have a learned opinion that it will work.

With such little deadrise, you might want to add an anti-trip chine.

The boat is going to have spray rails on it once completed.

Why is it that some Carolina boats have chines, while others don’t? Both designs always have spray rails.

Funny story about CAD design. For 9 years I rented a shed from Bob Derecktor in Florida. He used MAD to design his boats. Model Aided Design. We built a 50' sailboat together and model tested the design. Anyone in the shop could make their own version during the design process. I would make a model, then a mold off the model, then a part, then tow test those.
Bob took one of the best of then all, slit the bottom, pushed it down on the bench to take out rocker, then we glassed it back. It was better, so the process was repeated, and better again.

Since the hull was aluminum with a composite deck, I needed to get the lines into the computer for plasma cutting the frames. A boat designer Buddy produced a gorgeous set of lines from a CAD program of the day.

Bob looked at them, looked at me and said; "Do you think we should make one more model from these lines to be sure? I said Fk, I guess so. I did and the beautiful model that I used to make a beautiful mold which produced a beautiful hull was beautiful but slower. I guess there were no B Splines to match "cut bottom, flatten to bench and re-glass".

My Buddy pushed and pulled and tricked the program to exactly match the hull lines offsets I had given him. Another friggin model, another friggin mold and another friggin part and all good.
The boat won the Newport-Bermuda Race first time out of the box.
