Agree with what Steve says - the boats not run at any speed in anything that could give rise to a proper stuffing. I also think the bow design gives huge lift as soon as it gets anywhere near going under and the couple of occasions I have been on it when its come close its due to the short steep standing waves, that you just cant ride over - even then its more spray than solid water.
Its maybe the most solid boat I've ever driven - a proper credit to Andre and everyone he has working on them, and yes the all up weight is significant !
I'd also give credit to Steves full time skipper for having huge skill in handling the boat in every situation.
Defiantely worth making the time to have a trip.
