Barnacle Hull Care

Never miss a hull scrub or zinc anode change — keep your boat protected and seaworthy.

Barnacle keeps your boat's hull and running gear in peak condition with a smart maintenance schedule you can actually follow.

Track every recurring task — hull scrubs, anti-fouling paint, zinc anodes, propeller cleaning, and waterline polish — with next-due dates and last-done history. A color-coded status view shows what's overdue, due soon, or on track at a glance.

The Tasks reference library covers 15 essential maintenance jobs with recommended intervals and a complete tools list for each: hull scrub, zinc anode replacement, anti-fouling paint, propeller cleaning, sea cocks, bilge cleaning, sail cover care, lifejacket inspection, engine oil, fuel filter, hull wax, deck polish, navigation lights, bilge pump, and fender check.

Store multiple boat profiles with name, length, hull material, and home marina — perfect for owners or crews managing a fleet or family boats.
