I just got this wire furler set up on a 15 foot boat and it looks like it will work well. I used the same as HW and also had about the same problems with the sail interfering with the forestay and had to move the forestay at both the top and the bottom to get it away from the sail.
I’m also thinking about leaving the furled sail on the deck in a bag for trailering. Setup would be to just remove the bag, attach the halyard quick connect to the upper swivel and hoist.
HW, thanks for the info, definitely useful to me.
