Storm sails

Both of the furling sails on Zanshin are “cut” and laminated and sewn by the sail makers so that they form a certain curved shape and can function as air foils during normal use. This means that they are not flat surfaces but complex curves and when these are reefed (rolled up and shortened to reduce surface area in high winds) the sails lose more and more of their shape as they are made smaller. Sails usually come with 3 reefing points on them, although with roller furling sails the number of discrete positions is much more than the the classic 3 reef points. Each reef point equates roughly to 25% of sail area, so the 3rd reef point would mean that only 25% of the original sail area is left. But when furled in that much the shape of the sail is too baggy and it becomes inefficient; in additions even this scrap of sail can sometimes be too much in stormy conditions.
The solution is to use a storm sail (sometimes called Code Zero) for the foresail and a storm trysail for the main. Zanshin has a removable inner forestay installed which allows such a smaller storm sail to be hanked on (rather than rolled) and used in inclement conditions. The storm trysail is also run up a track on the mast and does not use the boom but is sheeted directly to hard points on the deck of the boat.
I have been putting off getting these two sails (and installing the separate track on the mast) and thus I don't have any pictures of the sails yet, but once I choose the sails and have them made I'll post updated pictures on this page.
