With respect:
The
asymmetric spinnaker, or MPS (multi-purpose sail), is properly spelled “cruising chute“, not “cruising shute“
I’ve not used the ATN Tacker, but the normally I fly the tack of my MPS only about 0.1m above the top of the bow pulpit on a non-adjustable strop (for simplicity). I sized the luff of the chute this way when I had it made.
So there’s no need of the Tacker as the tack never goes very far to leeward. Since the tack height is not adjustable; if I want more belly in the sail, I just slack the
halyard a bit. Having the tack low down also minimizes healing when you are reaching with the cruising chute.
However, if you usually fly your MPS tack way above the
deck, then the ATN Tacker would be useful to keep the tack from blowing far to leward; better to keep the tack close to the centerline of the
boat...
