About Ahern Maritime

Dedicated to What's Below the Waterline

Ahern Maritime is a specialist boat bottom cleaning service based on Long Island's North Shore. We focus exclusively on underwater hull maintenance — because a clean bottom means better performance, lower fuel costs, and a longer life for your vessel.

Marine growth like barnacles, algae, and slime can increase drag by up to 40%, costing you speed and money every time you head out. Our divers keep your hull in peak condition so you can focus on what matters — being on the water.
