Hi, I am considering buying a new FOC and have an old letter from Amel stating that the size should be 153.8% Genoa. Does anyone know the dimensions for that. Also would you install foam in the luff or not. I do not think mine (SM72) has foam. Would you recommend Dacron and any particular style. We are just a cruising boat so nothing fancy is wanted. By looking at the Amel diagrams that came with the boat, it appears that the luff is 17.1m, leach 16.15m and foot 9m. Does this comport with what I am looking for? Thanks for your input.
