I just blew my mainsail yesterday on my 1987 Ericson 34. It was an older but still very serviceable North measuring 37' 3" on the luff and 12'6" on the foot. I haven't found a good match on the used sails sites and the sail loft figures on this site do not match mine. Questions: (1) suggestions on finding sails for an Ericson 34? (2) do these measurements correspond with your figures?
