A few posters mentioned using the spin pole instead of bothering with a sprit, and that has been mentioned recently on SA as well, but I just don't understand how the tack of the sail is attached to the end of the pole, how the pole is kept from rising up (tweakers? downhaul?), and how it would be jibed. Could someone explain?
There are different ways to do this, there are one short hand sailor here in Norway who is using a system he is calling ASOP (Asymmetric Spinnaker with Oversized Pole)
He is using a spinnaker boom with length J + 1meter.
He uses three lines attached to the tack of the sail.
All three spliced into one snap shackle
The sail is tacked in front of the head stay (the usual way) with a adjustable tack line going to a cabin top winch).
Setting the sail is done as usual.
The pole is set on the windward side the afterguy is put into the spnnaker boom as yuu would do with a spinnaker afterguy.
The tack line is eased and the windward guy is hauled in to pull the tack to windward
Gybing the sail is done in this sequence (outside gybe)
-ease the afterguy while hauling in on the tack
-When the tack is hauled in do the outside gybe
-After the gybe - dip the spinnaker boom and set on new tack
I set my assymetric on a bowsprit but use a normal length spinnaker boom the same way as decribed above to pull the tack to windward for downwind runs.
Here is a video of this gybe
