Some interesting ideas there. I like PlaneSailing,s Rowing Idea , from the point of veiw of being able to put more distance between you and the
lee shore . Thats the biggest risk here I recon, the potental for the 4 mile buffer to rapidly disappear
The Idea of doing nothing ,
not keeping an eye on current and or tide drift could put you in a nasty position , while your waiting for your 30 knts [ or 50 knts as is someones want] to sail home with . Also to use the time to change sails etc would make sence .
And Cisco,s "let someone know the situation and position" would hopefully be the first thing we would all do. And thankfully I havent had to deal with that situation myself Cisco, but now Ive got some Idea,s If it ever happens.

And yes, spark plugs may come into play on the tenders outboard, while towing out to sea!!
