Need offtopic forum because...

I wanted to discuss an subject that doesn’t fit into the other board sections. I want to post it on Swaylocks because I know know people here are interested in making things, and I know there’s probably a general interest in the sea that goes beyond surfboards and into other craft and technology.

My idea:

Wearing drysuits is ok for an hour or 2, but I don’t want to wear one on the deck of a boat because the seals needs to be tight - especially on the neck.

Why not have a mechanism that holds the seals out out of the air but in contact with water collapses closing the seal - this could be mechanical with dissolved salts or electronic by 2 open electrodes that will join in sea water.
