The quintessential Californian classic race/cruiser - the Kettenburg 50
Custom | Modernized | Classic

Akamai is the ultimate modernized classic yacht, perfectly suited for racing, cruising, and entertaining. Her newly constructed composite hull - epoxy encapsulated mahogany planking - makes Akamai lighter, stronger, and faster than she has ever been.

Originally designed by Paul Kettenburg and built in San Diego, California at the Kettenburg Boat Works Yard in 1962. Akamai was rebuilt by C.F. Koehler at Koehler Kraft Boatyard, San Diego, CA in the summer of 2011.

Akamai's extensive reconstruction included a full new interior - keeping the original Kettenburg layout. With 2 double cabins, a quarter berth, and convertible settee, Akamai can easily sleep 8 guests or crew for overnights.  Her complete reconstruction included replacing some of her original Oak ribs with Purple Heart and all new epoxy-encapsulated, mahogany planking. She also has a new cabin sole, of Brazilian Walnut.

The addition of contemporary comforts and technology for improved navigation and offshore communication, such as dimmable direct & ambient LED lighting -  make Akamai well-suited for a modern racing and cruising lifestyle.

Most important to note is that Akamai's structural integrity has been further bolstered from the application of modern wooden ship-building techniques and materials that were not yet invented during her initial construction - such as epoxy encapsulated planking, for a stronger, fully waterproof, rigid hull structure.

Today, Akamai is stronger and faster than ever - ready to provide decades of maritime memories for her next family to cherish.

Racing Background:

Historically Akamai has one Transpac on record - and she is ready for the next! In more recent years, Akamai has performed remarkably well competing in the active  Southern California classic yacht racing circuit - competing alongside Dennis Conner's S&S, Splendor and CF Koehler's 10-Meter, Sally, as well as other notable Kettenburgs and other classics.

This certainly isn't your Grandfather's old wooden boat, but with the epoxy-coated hull, you can keep her in the family for generations to come.

Akamai is ready for whatever adventures you can imagine - whether it is competing in the next Transpac, racing against other classics, or enjoying quality family time while cruising the California coast. Just as her Hawaiian name translates - Akamai is a smart choice for your next yacht.
