having a hell of a time figuring out how big a diameter and wall thickness i need for an unstayed carbon fiber main mast
holding a junk sail (of 700 sq ft M/L at 42 feet on the mast
and 18feet at the battens) for my newly acquired, never floated, started building in mid 1980's Ed Horstman Tri-Star 42 that i am finishing out.
it came with a self furling
main (kenyon brand 55 feet long) that i am selling as i am old and like junk rigs for easy of single
handing and no damn clawing of wet cold fabric
So how large a diameter tube? all the sources i used to go to are now 404...
any ideas on where to start?
i am going to use an aluminum
tabernacle and industrial carbon fiber tube (no taper needed) at 20 feet and join with internal ferrules for strength.
thanks for any assistance....
