HI Mates. Was looking to buy 400cm Severne Red line RDM 400 mast to rig some of my Nash and Severne sails. Found a few used that have 21 IMCS written on the 400cm mast. What the heck? Aren't they supposed to be 19/18 IMCS and 430cm be 21 IMCS?
Thanks
Why check with Unifiber , a company that supplies masts ? Yes, they do have a chart of mast bend curves of others, to form a compatibility of sorts. This chart changes yearly, as some Sails have changed.
So why not ask Severne ?
