I would've had a very difficult time doing it in a beach cat without stalling, hitting somebody's boat and/or breaking out a canoe paddle. With the exception of a wind surfer, I had never seen a sailboat with a reverse gear before. He could head right for something, then throw it in reverse, back away and bolt off in a new direction under perfect control."

Thanks Rob. Sounds impressive, Having sailed engineless boats for years I can really appreciate the benefit of having a reverse gear!

My brothers proa has issues shunting, and getting caught in irons. Seems like this is a common proa issue, so it sounds like your rudder system works well. Not really relevant to your harry proas, but here is a video of my brothers 30 foot proa, and their attempt to sail across the Tasman.

Cool! That is a big trip for a little boat.

I don't know about their boat, but agree that the in irons (irons of death as one owner called it) does seem to be a problem for some traditional type proas. It is some or all of: hull shapes (lots of rocker), CoE/CLR imbalance and windward hulls which are designed to fly so are overloaded with excessive drag when the boat is just getting going. Many traditional proa owners wish for longer ww hulls.

Harryproas get round it with their rockerless hulls, fore and aft oversize rudders (no daggerboard required) and large buoyant windward hulls.
