ColdWeatherSurf said..So, my mast length is 410 and my sails luff is 415. Is it ok to use this mast or should i get a new one?
As far as I know there isn't much alternative, except perhaps a standard 400 mast. As Joe implies, there's more to masts than their length.
Modern sails are usually mast specific, in terms of their stiffness and bend characteristics. If you want the best out of a modern sail, it needs to be on a compatible mast.
