Miss Nylex went over a few times but never wreaked her rig in the capsizes.. Bruce Proctor has a few stories of these events including one where she self righted and he walked on without getting his smokes wet.. They went on to sail her home..
Point two also seems a little dubious.. I take my rig down as do most of the guys who have carbon masts here.. Actually one should wrap any epoxy mast to decrease the UV damage to the epoxy matrix.. Its also good as it keeps the mast below the epoxy softening temp (60-75C).. Unless ones mast is made from prepreg which has a 100degree C postcure temp cycle.. Its not that unusual under our sun to see the mast temp climb into the 60-75 degree levels..
Did you ask him about the 18sq wingsail? Wonde how it would go on a HT or A?
