1946 Custom J.M. Martinac Classic Fantail Motor Yacht

This 79-foot motor yacht was built in 1946 by J.M. Martinac Shipbuilders as a displacement fantail design. The wooden hull measures 18 feet 4 inches across the beam and is powered by twin Caterpillar D-334 diesel engines producing 240 horsepower each. The yacht cruises at 10 knots with a maximum speed of 12 knots and carries a range of approximately 1,500 miles.

The interior layout includes three cabins and three heads, offering comfortable accommodation for extended cruising. An electric windlass is fitted for anchoring operations.

One of the port engines was rebuilt in 2026. The boat retains the classical lines and construction methods characteristic of mid-century Martinac yachts, combining traditional wooden hull construction with reliable diesel propulsion.
