She was built in 1977 by Rysco Shipyard as an offshore supply vessel and converted in 2005 by Stabbert Maritime to an oceanographic research and explorer yacht. As currently configured she carries up to 19 guests/scientists and 16 crew.
Proposed for conversion by designer Sergio Cutolo, she would have a six stateroom layout with an 85 square metre master suite offering panoramic views and located below an existing ABS classed heli pad. The conversion is designed with a garage to carry a three man Triton submarine plus four jet skis in addition to a 9.1m tender and many more toys. A luxurious cinema and dive center add to the scope of adventure and entertainment choices. Proteus has had $3.5 million invested in her over the past three years aside from routine maintenance.
On display at the Fort Lauderdale International Boat Show, Proteus is down from $1.95 million to $1.3 million.
