My partners and I purchased #271 this past Spring and the mast was removed in the Fall. The mast step was in the most forward position which placed the mast about 3/8" behind the forward step face. The boat has a Furlex system on it which we use for daysailing and club racing(we lower the bearing and use Kevlar genoa). We would like to move the step aft and comply with the 25mm spec. Does anyone know what we can expect regarding performance and what we can do to take up the ineviatable slack in the furler? There is no adjustable turnbuckle on the furler. As an additional request we plan to change the halyards and sheets; what line and sizes are most people using?
