How about the ultimate pfd.....& yourve got room for all your mates
Some important technology used to stop life rafts blowing away when deployed could easily be adapted to a paddle board.
Notice the water bags hanging below the raft.
A suitable sized drogue could be mounted to the tail of a board, & automatic deployment happends when the legie breaks.
The tail would be held into the wind greatly reducing the windage & hence tendancy flip & fly away
Any good idea's or suggestions about deployment mechanisim all you designers out there?
