Did someone mention my name?
That's a bit bigger than mine and I've never seen one that size in person. Probably not as big a v hull as many ribs that size so if likely to be used in seriously challenging conditions I'd want to get a sea trial somewhere first.
The smaller poly boats compare well with small ribs and sibs. The concept should adapt well to bigger stuff, and there are certainly some used by fish farms around Scotland.
For what was described I'd also consider pioner multi - its mini landing craft style bow could be particularly nice for getting on and off beaches without getting in the cold Arctic water! That will definitely suffer from slamming in big waves though.
