When conditions are extreme yes, otherwise some are much worse than others. This is where some of the older boats were much more crew friendly. Where the forward section of the hulls flared out towards a flat(ish) deck level the spray from the bow would (mostly) be deflected to leeward and many main beams were set flush with forward deck level. This way the water didn't 'explode' when hitting the front beam on deck.
I know some will argue that these older flat deck designs were sometimes not as pitchpole resistant, but if the crew can see what they are doing it is less likely to happen in the first place!
Do I think think the lip/rail will do much on the Hobie (If it actually appears on the boat)? - No. What it has done is get people talking about a 'new Hobie F18'
