The sail does not collapse on itself off the breeze -- on the contrary, it becomes very full and powerful, especially up at the top, and makes the boat want to (or actually to) pitchpole because of all that power up high.
Okay Mary, you've made me question my understanding of sailing again. I thought the reason the traveller helped was by keeping power ON the top part of the sail when reaching. It seems to me that when bearing off, as you let the Wave's sail out, the top of the sail twists farther away and spills the wind, thus losing power. I thought the purpose of the traveller was to help keep the sail flat as it is eased, thus keeping air in the upper part and MORE power in the sail.
I thought the normal twist was part of the design to naturally de-power the sail as the sheet is eased, thus keeping the resort-rental-customer safer and LESS likely to capsize or pitch-pole.
