I just wondered what you think about the point the captain of the Morgan’s Cloud makes here about swept-back spreaders:
John Harries is a good friend and very experienced seaman and his comments make sense in a certain context. However, swept spreaders make sense in several situations. First, on higher performance designs which do not often run square with the wind, and where the extra roach and power more than makes up for lost projected area. Next, with small degrees of sweep, like eight degrees, which can be very effective in stabilizing the mast and reducing rig weight at small off the wind penalties.
Where I agree with John is on conventional slower designs with heavily swept spreaders, and triangular (as opposed to roachy) mainsails.
