Has anyone any actual experience with adding thin (1/4, 3/8. 1/2") flexible closed cell foam to their mainsail
in order to achieve buoyancy when the boat is knocked down with the mast
in the water
I'm thinking perhaps something like adding double sail panels
with the foam sandwiched in between - so if anyone has actually done something like this, I'd appreciate hearing the details of the good and bad things they learned.
I'm thinking about this for a small (20') unballasted planing sportboat. I want to prevent turtling if possible.
Overturning moments indicate that this would only be needed in the topmost 1/3 of the mainsail
to be equivalent to 100# of lead at the bottom of a 4' keel
Thanks for any guidance you can give,
