I've had my mast knocked down 3 times now by someone hooking the jib forestay and disconnecting it from the rack.
The way I had it arranged was with a ring, ball bearing swivel, and a hook. It seems the ring is not strong enough to resist a hit and it uncoils and down it all comes.
I've seen various ways of attaching all but thought I would put it out there and see what the Discussion site thinks.
Thanks,
Al Stall
