I would guess that mast
is not for a Cal 20
masts up to 40', the length of a 40' container, isn't too expensive. Over that, both road and ship transport gets a bit ridiculous. If you have a longer mast for road shipment, piggy backing on a boat
transport is the cheapest way to go. The problem is finding a boat
being shipped in the vicinity of the mast or vice versa. The container length I assume is the reason that most mast extrusions are 40' long with a splice for longer lengths.
