I came down from Anegada in Feb with 8-10 ft waves and same period however with SSE winds on a 52 power cat. I dog legged my way down through the waves with 8 other guys. Before you leave I would stow everything and have everyone sit up with you on the flying bridge and a life jacket on your daughter. It wasn't fun but was great practice. My main issue is the other 8 had run up a huge bar bill at CowWreck and werent much help

Like George I cant figure out the inconsistency of wind guru wave heights with NOAA wave heights and "only" 10-15kt winds but I am sure many of those on this board that are way smarter than I can opine

I might plan to stay at Anegada another day as you can never have enough time up there. Also check with your base (e.g. Moorings) and get the latest weather from them

Have a great time
