KAISOSI is one of the last Admiral Executive 40 built. The Admiral Executive was one of the best custom/production catamarans ever imagined. The concept was was to build a top tier fully custom equipped boat instead of building a base luxury catamaran and add options.

KAISOSI is probably the most unique of the series. The owners have upgraded even above the factory specifications with the help of the designer Angelo Lavaranos. The hulls were extended over 3 feet to compensate for extra weight and make a fast more stable catamaran. The keels were lengthened and enlarged to improve performance of the original, rather small keels, and the rudders were modified to improve balance.

The owners, have spared no expense to make KAISOSI the one of the best designed catamarans to suit their needs and the fortunate next owners. 

This boat has been home for the owners and has taken them from the African coast, South America, the Amazon River, French Guyana, Trinidad, US, British, Spanish and the Bahamas.

Even though the their sailing future may be coming to an end, they are enjoying the Eastern US coast, still sailing and loving it. Please call or e-mail me to find their latest location. They will be happy to show you the boat and tell you their story.
