When is it not?!
I vote foam. You got me thinking about what to do for my GT. I like the idea of foam under the gunwales. I could do it behind the seat backs. It would serve to float the boat up right but also stiffen the sides.
When is it not?!

Lots of folks foam in the whole bottom. Some want no foam below the water line and limber holes for draining. Both have their good and bad points. So what are you guys doing and why?
I know at least one beach where WE might be able to put this to the testcape man wrote: ↑Sun May 20, 2018 7:24 amMy dory has 13 separate compartments below the sole, each fully sealed and taped, and full of 2 part poured foam, sold here. The sole is sealed and taped to the sides and covered with glass. The only penetrations are the screws to hold the fuel tank and leaning post, and they are all drilled oversized, filled with epoxy, and predrilled. If I ever penetrate the bottom, the only water will be what can fill any void around the foam in that compartment, which will be measured in ounces.
I spent extra time and materials sealing each compartment, paying special attention to the chase tubes.
While indeed, shit happens, I am VERY confident there is no way for water to get below my sole without a major incident puncturing the bottom or the deck. Part of building the boat was to consider all this and make sure to do it right, as prescribed here.
The assertion that water will inevitably get in doesn't apply to my boat, or most others built here, and built right.
As to turning turtle if fully swamped, I hope we never learn that answer for an OD18, especially mine. I have no plans to ever be somewhere where that might even remotely happen.
What does your boat weight before you build it?Magnetic4 wrote: ↑Wed Aug 08, 2018 4:49 pmI just purchased plans for a C19 based on description that boat could be provided with Level Flotation as required by USCG.
Unfortunately absolutely no information on how to achieve this on the plans.
The minimal foam flotation indicated on plans between stringers is inadequate in my opinion.
Looked up the USCG info and fairly obvious that Level Flotation calculation should be undertaken by the designer.
Has anybody any information on how to make a C19 comply with the USCG Level Flotation requirements ?
Is there a supplementary shhet of plans available ?
I have a coworker who is working on a 20ft Lund, it has seen ~10yrs of use or so.
