We actually own a larger version of this boat (the 58') and while it is not an offshore
yacht, they are fine for coastal cruising. The general rule
of Bluewater Yacht owners is never be more than two hours from protected water.
In reality the hulls are plenty strong to handle moderate weather, and there have been more than one caught out during hurricanes and coming thru just fine. The problem with the design (and this is really a trade
off more than a problem) is they are shallow draft
with a lot of weight low, and very flat bottoms. This results in a very fast roll period with a lot of slapping. Which is just about the most uncomfortable motion a boat can have in big water.
We routinely run the boat from New Orleans
and have taken it as far south as Sarasota
with no issues, but waiting on a weather window is critical for crew comfort. The boat can take a lot more than I would ever want to (and I have crossed the Atlantic twice in the winter).
The upside of this design is a huge amount of living space, relatively efficient planing fuel
burn, and a massive bridge deck
