On the afternoon of March 31, 2016, the passenger vessel Adventure Hornblower was attempting to dock at the Navy Pier in downtown San Diego, California, following a whale-watching excursion. As the vessel made its approach to the pier, its bow unexpectedly swung to starboard and allided with the pier’s passenger embarkation dock. The Adventure Hornblower then accelerated forward until it struck the seawall at the foot of the pier. Eight passengers sustained minor injuries in the accident. The allision caused nearly $1.06 million in damage to the vessel, pier, and seawall.
