Congrads on your new boat. The nerves will wear off before long. We went from sailing 16-18' sailboats to sailing a 36' sailboat on weekends evenings and vacations. After your first couple of trips your confidence in you and your boat will improve. We are trying to work our way up to cruising a 40+' cat.
As far as the galley goes are you planning to cruise, liveaboard or be day trips, weekend trips, and vacations?
