When I've capsized my Wave, I didn't have any problem righting it. I'm at about 205 lbs; and with the sheet uncleated and the righting line over the high hull, it popped right back up, very quickly! Both times, it was in strong winds (20+), so that may have helped.
After uncleating the sheet, I climbed up on the low bow (and let it pivot around to the wind), pulled the line out of the pocket, threw it over the high hull and leaned out. It popped up so quickly, I had to dodge the hull coming down and grab the other end of the righting line to keep it from rolling on over the other way.
For me the toughest parts were climbing onto the slippery bow, then getting back onto the boat after it was righted. I posted a solution to re-boarding the boat on Catsailor's Wave forum.
Since yours was so uncooperative, you might make sure you don't have water in the mast holding it down. Mine was filling up with rain water (from a leaky seal in the comp-tip joint) till I drilled two TINY holes in the luff track near the base. Water trickled out for hours. Now I can tell the boat is lighter when I pull it up on shore, so I'm sure it helped with righting also.
Hmmm, water in the mast, that would make sense. I don't trailer, I have a place to keep her. I did take the mast down last week to add some 303 to the float and comptip, seemed normal weight, but I did not drop it 100%, so some water could have been in there, staying at the base, undetected. Probably would not take much water to create a significant hinderance when righting. I will check into that situation. Thanks!
