How long is a bit of string? Rough seas cannot be put into little boxes and comparisons drawn. A force 4 wind over tide in shallow waters could be terrible yet you can have a superb ride with a force 8 following sea wind with tide. I'm afraid it is a question of suck it and see. Sorry if that isn't helpful.
The idea is that the deep vee slices thru the water, so more stable ride than a flat-bottomed inland water boat, tho son't know the boat, and it won't be v stable if you stop, natch. Scuse if u know all this and are looking for detail detail owner-expertise. Good boat name. In a fifty footer upwind in a f5 I slowed down and a boat your size belted past at 25knots+ so probly fine! Doesn't feel like it when at rest tho, you have to gun it.
