An apparatus for protecting the hull of a watercraft includes a support. A submersible barrier assembly is connected to the support and is displaceable with respect to the support between an inoperative, submerged position and an operative surface position. The barrier assembly is configured to cover at least a submerged portion of the hull in the operative position. A displacement mechanism is operable on the barrier assembly to displace the barrier assembly between the inoperative and operative positions.
