DIAMOND'S GEM - 2007 56' NEPTUNUS 56 Fly
Fort Lauderdale Florida
$499,500 USD

The 2007 56' NEPTUNUS 56 Fly DIAMOND'S GEM is a yacht for sale located in Fort Lauderdale, Florida, USA.

This Neptunus 56 Fly Bridge Motor Yacht has amazing European styling which comes from her Dutch roots. She is a tremendous sea boat that is fun to drive from either the upper or lower helms. Diamond's Gem is equipped with a pair of preferred Caterpillar C15 800hp diesels that allows her to cruise effortlessly in the 23 knot range and can top out around 29 knots depending on vessel load and sea conditions. The spacious 3 stateroom layout is superb for a large family or extended cruising. Your outdoor entertainment space is unlike any other boat in her class. The flybridge hard top is very unique and allows your family and friends to catch some rays on the sun pads in front of the captain while the balance of your guests are protected under cover. There is a larger covered aft deck dining area completed with Grill and mounted TV. The hydraulic swim platform is one of my favorite features for the family to hang out on the floating beach and store your favorite water toy.
