Apologies to anyone who thinks renewing this year-old thread is without merit. In response to posts about prices, here is what I have been quoted for downwind sails
for a fractional rig self-tacking 27' trimaran
.. a bit different than the bigger boats discussed in this thread. And I suspect the worries, discussed above, about being surprised by a blow would be less for these smaller sails
Wingaker, including snuffer, bag, and shipping
42 square meters = US$2286
51 square meters = US$2642
The Wingaker seems very much like the Parasail, but with vertical fabric
battens in the wing? Hard to find pictures showing the front; lots of owner videos from the boats.
Parasail, including snuffer, bag, and shipping
46 square meters = US$2447 (essentially same as Wingaker)
The Parasail is smaller than their Parasailer, and does not have an opening above the wing. Advantage to the Parasail (assuming they do the same deal as with Parasailer, and that their locations are convenient enough) is you can go for a training ride with them and apply the cost of the ride to your purchase
kit from SailRite
20.59 square meters = $720
I'll let others estimate what that would cost already sewn. Double? And then adding hardware
... a furler
would seem most comparable to the wing spinnakers. Looks like it becomes a wash, if the wingers have the apparent wind
angle ranges they claim. Sailing a bit off of dead downwind, enough to keep a windward hull
out of the water
, would seem the best strategy for a tri.
The wingers seem like more durable sails, too.
