Pieces of the boat, shoes and clothing were recovered on the beach halfway between Pacifica Pier and Point Mori, according to KTVU.

Officials said they did not receive any distress calls in the area, and it was unclear if the boat somehow became loose or if there were any mariners that needed assistance.
