We ran our 1998 480 with 3196's to the Abacos many time from Florida. Hit 12 footers a few trips which made for a rough go for the passengers. Boat handled it fine. Doesn't like cross the beam seas over a few feet (and what boat does) Rides dry on the bridge in anything less than 6-8's. One trip from Daytona, Ponce Inlet, direct to Walkers Cay in the Bahamas, about 10 hours, the girls on board started getting sick after 4-6 hours of 6 footers on the nose. Again the boat did well. We usual slowed down to 18-19 knots in anything over 5 footers. We were carrying an 800 lb Rendova on a TNT platform. I would always recommend use as much trim tab as possible. With the nose held down the boat is a dream at 22-23 knots cruise in anything less than 4 footers.
