Sea-kindliness of Atlantis KRS7 rounded/stepped hull ??

I am considering buying one of these, but have not seen or sea-trialed in one yet. Her hull seems quite radical with its rounded (vs. V) stern profile and drag-reducing "speed steps". They seem like novel/beneficial features, but why do so few other RIBs have hull features and why did they not sell well enough to keep the company in business? I am looking for information and/or testimonials on how well that boat handles hitting ~1-2M waves at good speeds. I can see how the flatter hull aft will improve planing performance, but I fear it might hit the troughs with pretty hard slams...? Thanks for any feedback.

It's a very expensive process to start up a rib manufacturing/selling company and unless you have large resources you need to sell well and quickly or have other business income streams or low overheads. I don't belive that Atlantis had either. Their premisises were not cheap and the market at the time they started wasn't particularly bouyant.

Adam is a very good designer and the hulls/tubes were well made by established hull and tube companies. Their unit was just down the road from ours at the time and I went down and had a look at them and thought were well made

Looking at the designers pedigree and the wave height you are talking about I would be surprised if it was a problem at all, However I think the ride would be quite firm (think Sports Car rather than Saloon)
