Wow! That sure is a tiny galley for a 65' cruiser. Is it the main galley?
FWIW, with our living on the Lake Michigan shoreline all our 72 years, boating, fishing, waterskiing, swimming, etc is a way of life and we are/were no exceptions. If we weren't boating because it was windy and/or rough on the huge deep lake or chilly, we'd be gone in one of our RV's or up at our 4.3 acre hideaway in the 532,000 acre Manistee National Forest with literally thousands of miles of motorized trailbike marked trails to play on, etc. Winter was always snowmobiling up there before and after our annual Florida trip to our place down there. No moss ever grew or grows under our feet and we love it still!
