The cost of fouling
A slime layer becomes weed, then barnacles. Each stage adds drag — burning fuel, costing speed, straining your engine and eating through anodes. A single season of growth can quietly halve your performance.
We remove it gently, in the water, without ever touching your antifouling coating.

Diver showed up on time, sent a full photo report the same day. Boat feels noticeably faster.
