I still think its posible though. I would never leave another sailor alone in distress. I work in the Coast Guard and our mission is to save lives first, then try as hard as posible to save property. It is what we do best. I still think that if you tie the right side up boat to the capsized boat, release all sails, IE bring them down, pop the rudders up I seriously think it is do-able.
Although I will never see myself sailing solo with another friend on another beach cat in over 15kts winds. Unless of course its a reggatta with chase boats to assist.
