I only purposely capsize rented boats.
The H-16 is relatively easy to right with a crew and it can be fun on a hot day. I've been out with kids that want to do nothing but capsize. It can get exhausting.
I had a Nacra 5.2 for many years that I never capsized out of fear. The only problem with never capsizing is that I never really sailed the boat to it's limits, which lowers the fun factor on fresh days. I'm pretty sure the mast was not water tight so I didn't take any chances.
I've crewed on a Hobie 20 and a Nacra 20 and have gone over on both accidentally. The skipper had the boat set up well so righting was quick and without problem. They were both spinnaker boats so we never capsized on purpose, but accidents happen.
I would say it is better to do at least one under controlled circumstances just to know what the boat feels like and how hard it is to maneuver on its side (or worse, turtled). A little confidence goes a long way when you are squeezing every ounce of performance out of you boat.
As far as preventing it, I usually depower upwind by making the sails as flat as I can using the downhaul and outhaul and moving the main traveler about 1/3 out (on the Nacra 5.2 it is even with the hiking straps/jib sheets). Downwind I try to twist the top of the sail off the wind by bring the traveler all the way in and easing the mainsheet. I don't know if this is the best way because sometimes in a gust the boom will go flying up. If anyone has any better ideas let me know.
So as far as I know: flat upwind, twist downwind, never let go of the mainsheet, and know when to stay on the beach.
Be sure to post some pics when you get your cat!
