I'll stand by my original post as I tried it... the issue comes in the case of an emergency and that
dinghy is YOUR
life raft... do you want to fiddle with why it doesn't release due to water, humidity, or corrosion or does a simple bowmans knot do the trick to getting it off deck and in use...I did the exact idea you want to use - and it took way more time to get it to release than it it did to secure it... sometimes sailor knots are your best friend and you may want to keep that in perspective....
