I have to laugh at those "long distances" in the BVI.
Leverick to Anegada is only around 20 miles or so.

How about 60 miles of open Lake Superior water in a 22' cuddy?

Or 120 miles in one day most of it in total fog (same boat)?

Remember that a powercat runs in a straight line and you can choose the speed. We ran our 474 and 8-9 knots and enjoyed the ride. You could probably run that 433 at double that speed if you didn't mind paying for the gas.
