1960 Classic Angelman Moon Beam Ketch

San Pedro, United States


Sea Moon is a stunning classic Angelman Ketch, designed by Hugh Angelman in his retirement years and built by Maas Bros in Breskens, Netherlands. Sometimes referred to as a South Coaster, she is a Moon Beam ketch design that has been lovingly maintained by a series of knowledgeable owners over the years and is still as timelessly elegant and beautiful as when I first personally encountered her over two decades ago. Constructed of mahogany over white oak, with scantlings comparable to a much larger vessel, she is safe, sturdy and yet swift under way. 

Sea Moon turns heads wherever she sails. Be a part of her sailing history and take on the mantle of stewardship for this gorgeous vessel! She's currently located in the most affordable marina in SoCal (also the closest to Catalina!) and her slip is transferable with marina approval. Call to see.

The U-shaped galley is to port, equipped with a 2-burner LPG gimbaled stove, oven and stainless sink. The engine compartment is centerline below the galley counter. Forward is the salon with a dinette to port and settee to starboard, and in the forepeak is a double berth and open head.
