Powercats as liveaboards

[LibertyCall]

I have noticed that powercats seem to post very impressive economy numbers, which has piqued my interest in them in lieu of a trawler for a liveaboard. In addition to the economy, I am impressed by the shallow draft (looking at a Jet-powered model) and huge salon. Anyone got any up/down advice on them?

How do they handle rough water?
