Sail trim with in mast furler

We have an in-mast mainsail furler. Can we loosen the mainsail halyard as part of trimming the sail or will it screw up the furler? (This assumes we retighten the halyard before we furl the sail).

Don't see why not, but of course that option is only going to be available if the sail is fully deployed....(says Captain Obvious..)

Re: Sail trim with in mast furler

Having an in-mast furler pretty much precludes efforts for sail adjustments to be very effective. We raced Newport-Bermuda with such a rig, and despite having a full racing crew tweaking everything we could the entire way, it only seemed well-set for about ten minutes of the three day trip. Vertical battens might (repeat: MIGHT) help, but battens can create major (repeat: MAJOR) problems with snags and rips inside the mast twenty or more feet up. A friend with in-boom furling had a batten poke through his sail, and that was a major fiasco, even with it accessible at waist level. Making the sail tough enough to avoid such batten problems makes it so heavy that you wouldn't want to race with it in anything under 25 knots of wind. R/F mains are cut so that they roll up nicely inside the mast or boom. Performance is not the prime directive. Easing the halyard on such a sail going downwind may add .00000002 knots to your speed in certain conditions. Or it may not. If you want to go faster, or race, get a different rig and (therefore) a faster sail. In the meantime, don't worry about adjustments that won't make much difference, and enjoy the ride.
