Boat Painting

Bottom Painting is a critical component of your boat’s maintenance plan.

Detailing Services

Boat detailing packages using the most advanced products on the market are available. In the summer sun, your boats exterior needs continuous care to maintain its appearance. A monthly washing and quarterly waxing schedule keep your boat looking good and preventing a costly repair to re-finish the boat due to sun damage.

Old Harbor Marina recommends power washing at least once throughout the season, as this will prevent bottom drag and increase fuel economy. Most boaters are surprised by the dramatic change in performance by simply power washing. Call us today, contact us online or just stop in to schedule your power washing cleaning today.
