VESSEL HISTORY & CONSTRUCTION:

“Cohort II” is hull #31 of approximately 40 yachts built under the direction of Robert Vaughn in Miami during the 1970s. hull is heavily hand-laid fiberglass with a full keel and cutaway forefoot. Deck and rig design were based on Adriatic Yachts’ plans (Alpha 48) from Pompano Beach, FL.

The original build quality was exceptional, and the vessel has benefited from continuous upgrades since her 2010 purchase by the current owner. Major refit work occurred between 2010–2015, with ongoing improvements through 2020+. Only lightly sailed in Florida and the Gulf of Mexico, this boat is ready for offshore adventures.
