Treasure hunters Sub Sea Research team up with Howe and Howe Technologies to recover 'Port Nicholson' cargo. Last year, Sub Sea Research made international news with the announcement of their discovery of the $4 billion gold and platinum cargo aboard the SS Port Nicholson, a freighter that was sunk by a German U-Boat off the coast of Massachusetts in 1942. A year on, Sub Sea Research has teamed up with Maine-based, award winning technology company Howe and Howe, which designs and builds custom vehicles, robotic platforms and fabricated goods.
