I have thought about how I would tow another boat in such a situation, and figured that I might have to rig a Navy-style towing bridle to the rear eyepads, so as to clear the Hobie rudder assembly and to prevent yawing. But I guess your "hand-holding" worked OK, and didn't dislocate the ole shoulder?
I couldn't come up with any brilliant solutions on where to hook up -- there wasn't a lot of time. But the "over the shoulder" style worked pretty well. Even with the Turbofins, I wouldn't be able to dislocate my shoulder! Also, being able to play the line out and reel myself in helped when turning. Keep in mind, that Adventure doesn't exactly spin on a dime so being able to manipulate the line was really helpful. The Sport would actually be a superior tow vehicle because of its manuverability!
Your Bridal idea would probably work great with a lighter tow where you could get more speed and rudder control, or where you had an extended tow. You would probably want some sort of a shock-cord mount though, especially in any kind of sea conditions. The only problems I could see would be inaccessability to tend the line or for an emergency disconnect; keep in mind that you might still foul the rudder assembly when turning.
Dick, what would you think about launching a "Hobie rescue squad" where Hobie would provide members with the proper rescue gear, consisting of a free Hobie rescue
hat? Heck, the great PR would probably pay for the hats!!
