What Indoor Boat Storage in Mercer Island Includes

Indoor and outdoor storage with winterization options. Every job in Mercer Island is mobile dockside service. We come to your marina, slip, dry storage, or driveway with a fully equipped truck.

Storing a boat through a Mercer Island winter is harder than it looks. Long rains, moss and the odd hard freeze take a toll on boats left under a tarp, so we offer heated indoor storage with pickup from Mercer Island boat launch and the rest of Mercer Island.

Mercer Island Local Coverage: Private docks and Lake Washington boathouses.

Why Mercer Island Boaters Choose Divine Marine

Mercer Island boathouse owners who want the boat out of the water for winter use our concierge pickup from private docks and the Mercer Island boat launch, with heated indoor storage and spring delivery back to the lift.

Mercer Island boats are almost all kept at private docks, lifts and covered boathouses along East Channel and the West Mercer shoreline. They are well protected from weather, but tight boathouse quarters, low light and limited dock access make every job a logistics exercise.

Storage customers in Mercer Island can add off season detailing, fiberglass repair and electronics upgrades while the boat is inside, then get spring commissioning and launch coordination at Mercer Island boat launch or delivery back to the driveway.

Mercer Island is a short run across I-90 from the Eastside, so island jobs fit easily between Bellevue and Seattle appointments.

Shane at Divine replaced the Fusion stereo and speakers on my boat. He did an incredible job guiding me to the right solution and then doing the install. He was mobile so the experience was quite convenient and the workmanship was of the highest quality. In addition, he gave me recommendations to other service providers to do repairs on my boat. My experience was terrific and I highly recommend Shane and Divine.

Shane is wonderful to work with. He put a much needed upgraded sound system on my yacht in Lake Union and some other nice gadgets. Beautiful workmanship.

Indoor Boat Storage FAQ: Mercer Island

Common questions from Mercer Island boat owners about indoor boat storage.

Do you pick up boats for storage from Mercer Island?

Yes. Concierge pickup is available from Mercer Island boat launch, Luther Burbank Park dock and driveways across North End, First Hill and East Seattle. We coordinate the haul out or trailer pickup and handle transport to our heated indoor facility.

How much does winterization cost for a Mercer Island boat?

Winterization is a $450 flat rate. It protects the engine, water systems and plumbing from freeze damage, which matters for Mercer Island boats kept near Lake Washington through the winter.

Can you work on my boat while it is in storage?

Yes. Mercer Island storage customers often add detailing, fiberglass repair or electronics upgrades over the winter so the boat comes back ready for Lake Washington in spring.

Can you work inside a covered boathouse?

Yes. Most Mercer Island boats are in private boathouses or on lifts. We bring compact equipment, portable lighting and protective covers for the dock and boathouse, and plan the job around tight access.
