Thanks dbow for the link.

I see your point Bob, loads are much higher in our genny.

On the J29, we have two trimmers. When the 1st trimmer breaks the old sheet, the 2nd trimmer is taking in the new sheet very fast under little load. He then takes one wrap on the leeward primary, jumps to the high side with the tail takes 2 wraps on the windward primary, the #1 trimmer is waiting with the handle, slaps it in and trims in the last 2-4 inches under normal load.

If we are in light-moderate air (a lot of the time here in Detroit!), the #2 trimmer pre-loads the new primary with wraps and handle, and stays on the low side for fine trim.

No extra hardware involved, and the weight shifting occurs so fast (during middle of the tack when the boat is flat) that no time/speed is lost.

There is some side load on the winch, but the deck is very solid there, and I don't see that being an issue with most boats.
