OUR SERVICES
Everything your boat needs, from one team.
Tap a category below to view its services.
Hull Cleaning
Keep your hull clean, efficient and protected.
A fouled hull burns more fuel and costs you speed.
Zinc Replacement
Proper zinc maintenance helps protect your underwater metals.
Worn anodes let corrosion reach the shaft, propeller and running gear.
Underwater Inspection
Identify issues before they become expensive problems.
You see what is happening below the waterline without hauling out.
Marine Maintenance
Routine maintenance to keep your boat running reliably.
The engine starts when you need it, not when it feels like it.
Tune-Ups
Preventive service designed around your vessel.
Small adjustments now instead of a large repair in season.
Mechanical Repairs
Professional troubleshooting and repair when something isn't working as it should.
One team diagnoses and fixes it, so you are not coordinating vendors.
Oil Change & Impeller Replacement
Scheduled oil, filter and impeller service.
The two items most often skipped, and the two that stop a day on the water.
Top Wash
A clean boat starts from the top down.
Salt left on the surface is what dulls the finish.
Wash & Wax
Protect the finish while keeping your boat looking its best.
Protection now is cheaper than restoring gelcoat later.
Polishing & Detailing
Restore the appearance and maintain the finish.
A boat that looks cared for holds its value at resale.
