A fishing tournament in Gloucester kicks off; and the crew of the Pin Wheel play a prank on the Odysea's Captain Ralph.

The fishing teams are threatened by great white sharks. Included: A shark slams into the Christina; Tyler must risk life and limb to untangle a harpoon line from the Pin Wheel's propeller in the shark-infested waters.

The crew of the FV-Tuna.com relocate when amateur boats start creeping in on their territory; a weekend warrior runs over Kevin's anchor line; Tyler ventures out on his own after giving his crew the week off.
