After numerous trips on Sandy, my Tiki 21, I am just not sold on the Wharram wingsail. Trying to reef singlehanded on a rough sea is quite an event. A wet mast sleeve is difficult to lower in 18 knots while dodging a swinging wooden gaff. I think that any gain in efficiency by the mast sleeve, is lost by the extra windage aloft of the gaff and associated rigging. I'm thinking of removing the sleeve and gaff and creating a fat headed full battened main that is laced to the mast. Thoughts anyone?
