A method of protecting a plastic boat hull against blistering, comprising the steps of applying an outer gelcoat layer to the inner surface of a mold, applying a layer of barrier coat material of microspheres thoroughly mixed in a synthetic resin matrix to the outer gelcoat layer to form a barrier coat layer, bonding the barrier coat layer to the outer gelcoat layer, applying an outer layer of fiber reinforced synthetic plastic to the barrier coat layer, bonding the outer fiber reinforced synthetic plastic layer to the barrier coat layer, applying successive layers of fiber reinforced synthetic plastic to form a laminated boat hull having a series of fiber reinforced synthetic plastic layers with an inner layer, and applying an inner gelcoat layer to the inner layer of the fiber-reinforced synthetic plastic layers. A boat hull which is protected against blistering on the underwater surface comprises successive layers of fiber reinforced synthetic plastic having an outer layer having water soluble materials incorporated therein, a barrier coat layer of a barrier coat material of microspheres thoroughly mixed in a synthetic resin matrix bonded to the outer layer to form a barrier coat layer, said barrier coat layer having an outer surface, the microspheres being impermeable to water, and a gelcoat layer bonded to the outer surface of the barrier coat layer, the microspheres having passageways between them which increase the length of passage of water to water soluble materials in the layers of fiber reinforced plastic.
