Explanation / Answer

1.On August 17, 2016, about midnight local time, the fishing vessel Lydia & Maya was returning from fishing grounds in the Gulf of Maine to its home port of Boston, Massachusetts, when the vessel capsized. All four crewmembers abandoned ship into a liferaft and were later recovered by a US Coast Guard helicopter.

2.The Lydia & Maya was a commercial fishing vessel that worked off the coast of New England fishing for groundfish, such as pollock, haddock, and hake. The vessel was equipped with a main boom to lift the nets, two outriggers to stabilize the vessel while fishing, and winch-driven reels to deploy and retrieve the fishing nets for stern-trawling operations.

3.Based on interviews with crewmembers, the vessel capsized to starboard. The tendency for a vessel to capsize increases if its center of gravity is moved higher. When cargo or gear is stowed on the upper decks, as was done on the Lydia & Maya, the location of that cargo or gear weight adversely raises the vessel’s center of gravity.There were several factors that likely contributed to its capsizing:

(A) Leaving the catch suspended from the boom while transiting. Until cargo is lowered to the deck, the cargo’s center of gravity remains at the height of the end of the boom, thereby reducing the vessel’s stability.

(B) Blocking the scuppers on the stern of the vessel while transiting, which prevented accumulating water from draining overboard. A deck filled with water creates an undesirable free surface effect, while the weight of the additional water increases the height of the vessel’s center of gravity and decreases its freeboard, consequently reducing the vessel’s overall stability. 4 Additionally, high water on deck may begin flooding the vessel through non-watertight hatches and doors, which are often left open.

(C)Breaking of the center boom, which resulted in the 7,000 pounds of fish in the net likely falling onto the starboard side of the main deck. These events likely shifted the vessel’s center of gravity to starboard, considering that a starboard list was reported.

(D) Shifting of the cargo of ice and fish, as well as the vessel’s fuel and freshwater, which likely was a result of the vessel’s initial large heel to starboard. This shifting would move the vessel’s center of gravity further outboard to starboard, increasing the heel even further.
