Don't worry with the pounding...maybe they pound a bit more than deeper narrower hull design, but it sure sails better...
It's a sailboat that sails...go for it, don't let it be an issue.
You can buy an Old Shoe that doesn't pound, but doesn't sail either..
And you will end up sailing more time, than pounding..
GO FOR IT
I don't know about that. My old wooden shoe will average 7.5 in 10 knots of breeze and run with a similar LOA plastic boat and when the wind is up over 30 knots, she'll run off and hide from them. We averaged 10 knots for a 100 NM trip in 40+ just fine. Granted, she won't run with Giulietta but neither will that 423.
