Well the Life Buoy invention tonight turned out to be pretty lame.....
Not even worth posting a link....
To save anyone looking, here it is, but it's not worth viewing....

(Actually, it's OK, but it is not relevant to Down Wind Paddles, and it is heavily reliant on the life buoy and the person, 1 - finding each other, and 2 - staying together.... it is a pier based, or man overboard based system)...
