I have one and tied it to the dolphin striker yesterday. I capsized my Hobie 16 and couldn't tie a not it the darn thing because of the bungie cord in it. I gave up on it and used my docking line. I couldn't pull the boat up anyway.... I struggled for a 1/2 hour with a garbage back of water over my shoulder with at least 60 lbs of water in it + my 185 lbs and just couldn't do it. A power boat had pity on me finally and pulled me up. That was good since I was on a long drift across the lake miles away from my truck and the sun was going down and I was getting quite cold.....
The water bag feels really heavy and hard to handle. I'm thinking a righting pole or maybe I need a Hobie 14 instead of a 16.....
