Why Underwater Hull Cleaning Saves You Money on Fuel

Most boat owners think of hull cleaning as maintenance. It is — but it's also one of the best ways to cut your fuel costs. Here's why.

The Drag Problem

Marine growth on your hull creates friction — also called hydrodynamic drag. Even a thin layer of biofilm (that slimy green coating) increases drag measurably. Barnacles and hard growth make it dramatically worse.

Heavy biofouling creates drag, and a boat that has to push through it can burn more fuel to reach the same speed.

Beyond Fuel Savings

A clean hull also means less strain on your engine, longer bottom paint life, better handling, and higher resale value. It's one of those rare maintenance items where the ROI is immediate and obvious.
