It was extremely difficult, and quite frustrating, trying to achieve a good sail shape when fully unfurled. The draft
was difficult to control. When partially furled (reefed), wrinkles would appear. Smoothly furling the sail completely was a challenge, and usually had to be (at least partially) refurled every time.
It could be that this particular sail was blown out, or was poorly cut, or simply the wrong design. I just don't know.
The gooseneck fitting seemed to be a weak point, as was the entire foil that was supported only at the top and bottom. I worried if the rig could take heavy stress.
Finally, the manufacturer was out of business and there was no support.
In my case, it was like a breath of fresh air to pitch
the entire mess and go with a slab reefing, loose footed full batten main. Pointed several degrees higher after the change, lost
all that weight up high, and finally achieved the sail shape, over several wind
speeds, that I had sought.
