Patent ID: 7739974

Claim:
An antifouling repair identification and continuing protection system for a submersible object, comprising a first layer disposed on said object, and a second layer disposed on said first layer, said first layer having a surface with at least one ablation-exposed region due to ablation of said second layer due to wear of said second layer over time, wherein all three of the following conditions are conjunctively satisfied: a. each of said first and second layers comprises antifouling material; and b. said first and second layers are visually distinct from each other such that said ablation-exposed region of said surface of said first layer is visually evident through said second layer to positively identify a need for repair and also to precisely identify a location of ablation of said second layer for repair; and c. said first layer continues to protect said object from fouling including at said ablation-exposed region, notwithstanding ablation of said second layer at said region, until said repair can be attended to at a later time, whereby said object continues to be protected from fouling after said ablation has occurred and before repair can be accomplished.
