Howdy, just got one of those brand new OD sails... haven't sailed that
aspect ratio in 20 years now, should make my sailing a bit easier...

Question is: what mast to use? I have old masts lying around. Are the
red ones (1985 upwards) that were used for mylar AA9999 format gonna be
good enough? If I have to buy brand new, what kinda mast should I get
for a windsurfer OD sail?

Thanks in advance for pointers.
