Ronald,
Most any of the latest and greatest boats will handle these conditions fine, including most of the F16's (Viper and Nacra F16 are likely good choices), F18's (C2, Infusion, Wildcat, Cirrus R is probably fine as well), and the Nacra F20c. Nacra sails all their designs in the North Sea for testing as mentioned above.
Frankly any boat designed in the last 10 years is going to work fine for you, you just need to learn how to sail it in your waters; all will be better than anything you sailed 20 years ago. In short, steep chop, there is no substitute for waterline, so get the biggest boat you can afford and are comfortable finding crew for.
The Atlantic ocean can be nasty depending on where you are (Hatteras is no picnic). My primary launch location (Chesapeake Bay, not open ocean) can also be nasty, the waves break right on the beach, and in the right wind and current the launching is tougher than anything I saw in Tybee (not as tough as the northern launch points of the Worrell). We also see short, steep chop off my beach and my TheMightyHobie18 handles it fine, my N20 didn't even care. The latest F16's, F18's and F20's are going to do better than either of these boats in these conditions.
Sam,
sorry to say, but you don't have a clue from what conditions he is talking. Indeed a Wildcat is less suited than a Tiger, because of the flat wide hulls, the high aspect ratio daggerboards which requires for the same area (grip,) more draught. As flat hulls and high aspect ratio boards are quite common nowadays I fully understand the point. I am not saying it is imposible to go with those "modern boats" through the surf at flat beaches, but it is more difficult, or in other words with "old style" boats, you can out in stronger on shore conditions.
Ronald,
Nothing special to do with volume distribution though. I find that the "wave piercing" hulls handles better waves as long as you keep the weight balanced (and does not overload the boat). They are not piercing, just do less rock.
Maybe sombody gives you a ride with a F16 so you can get a better impression than just reading mails.
Cheers,
Klaus
