Hi - I have an O'Day Mariner, about 19', 1973. I don't have access to this boat (moored, no tender). Unfortunately I have gotten the sails for this boat confused with sails for two other boats. Does anyone know the actual dimensions for the luff and foot of the main, and maybe dimensions for a jib (forstay length)? Thanks for any help you can give. rowellcf@verizon.net
