Because the cruisers ain't " cruising" their " passive" but BOKA on Vanguard against lost of hope. The " vast whale of a vessel" that can float your boat.
One boater said it was probably about feet long, just minding this business in the Bahamas until a dog spots the monster cruising beneath the surface and cannonball, the dog jumps into the water and starts chasing the shark away.
Their maximum speed of 40 miles per hour is faster than that of a great white shark or orca whale, and even at their comfortable cruising speed, they can cross the Atlantic in a couple months.
