..... and woven (dacron) TAPE added to the edge of the foot section, to replace the 'strength' function of the boltrope.For best results I think at least the old bolt rope foot (and any 'shelf') should be cut off, but as BP indicated you won't have that wee bit of roach in the foot unless the sailmaker adds it.
This was a huge difference for us when we went with a new loose footed main. The outhaul was so much easier to use as there was no friction from a bolt rope. Shaping the sail for varying wind conditions is so much easier now. We also have end boom sheeting and mechanical advantage on the outhaul.Lot's of great info already!
I was contemplating this as I find the slot for the foot on the boom is tight and makes adjusting the outhaul difficult.
A clew strap works as well, and doesn't need to be 'slid out' of the slot when you take the sail off.......... you may want to purchase a single slug that fits the bolt rope slot and lash it loosely to the clew, so you can adjust sail shape easily while trying the loose footedness. (sure, it's a word...look it up.)
Bob, I raced with an (attached) shelf footed racing mainsail for many years before the advent of loose footed mainsails, and never saw a significant difference in terms of speed or pointing ability, except in light air. My boat, with a shelf footed mainsail, was every bit as competitive against loose footed racing mainsails as it had been before they appeared on the racing scene. If you think about it in terms of basic sail trimming principles, the reasons will be clear.aelkin:
I agree with you. But BS uses used and very worn out sails on his boat. It figures that he would see no difference. IF a loose footed main was NOT more efficient, why does every performance oriented boat today have a loose footed main?
There may be reasons not to have a loose footed main, particularily for cruisers, but the reasons do not include performance.
