I'm 185 lbs and I still get a little nervous about righting my H16 if it gets rough. I just bought a float and a water bag which seems to work OK for me, but I've also thought about buying a Soloright righting system. I've included a link. It works by moving your weight farther off the boat, effectively making you heavier. Maybe someone else in the forum has experience with how well these work, but it looks like it might be a good investment if you want to push the envelope a lot.
