I have a 1998 Bavaria Holiday 35, and would like to know how tight the forestay tension needs to be, but I have a furling genoa, so maybe someone can advise how much it should move for and aft when pressure is put on by hand, or maybe it shouldn’t move much at all, and is there such a thing as a tensioning device that could be fitted instead of the the 2 pieces of stainless steel which fit between the fitting on the bottom of the furling gear and the fixing point on the deck of the boat, and the distance between these points is 150mm centre to centre.
