Hi David,

I'm not sure if I am seeing this right, but do you think that the drive from the servo-powered drum to the free-wheeling one should be crossed over (each drum moving in opposite directions) ? That way you would provide more slack to the "non-tensioned" brace (by moving its pulley further forward) & less to the "tensioned brace" by moving its pulley back ?

The "gear ratio" between the 2 drums would have to be quite large to allow for the servo drum to make 4 or 5 turns & then have the free-wheeling drum only make 1/4 of a turn.

Brilliant idea - still trying to get my head around it ! Looks like it might be a very elegant solution to the problem of tacking jibs - slacking off the leeward sheet before hauling in the other side.

Just had a thought - I was looking at it from a jib crossover point of view - providing slack, instead of a brace point of view - taking up slack.

Could work for either ! - Nice.

Thanks & Kind Regards,

Peter D.
