Indoor Boat Storage: 12x30 and 12x40 Enclosed Units

Shadow Storage Lake Roosevelt rents indoor enclosed boat storage units in two sizes, 12x30 and 12x40, for $300–$500 a month. The units are fully enclosed but not climate-controlled, and they're at our lot in Davenport, WA, near the Fort Spokane boat launch on Lake Roosevelt, not in Spokane.

If you live in Spokane, you can still use them. Our All-Inclusive Winter Package picks the boat up from you and brings it back in spring, and the package can use an indoor unit. Pickup is available up to about 2 hours from our facility.

Each unit is enclosed on all sides with its own door.

Will my boat fit?

Measure the whole package, not just the boat:

  1. Length. Measure from the tip of the trailer tongue to the farthest point at the back, usually the outboard lower unit or swim platform. That number has to be less than 30 or 40 feet, with a little room to spare.
  2. Width. Measure the widest point, usually the beam or trailer fenders. It has to fit through the door and leave room to get past.
  3. Height. Measure from the ground to the highest fixed point on the boat sitting on its trailer, like a windshield, T-top, or tower. It has to fit through the door.

If you give us those three numbers on the phone, we'll tell you which unit works or whether covered storage is the better fit.

Not climate-controlled: what that means

Our indoor units are not heated and not climate-controlled. Inside, the temperature follows the weather outside, so in an eastern Washington winter it will get below freezing.

What indoor storage does do:

  • Keeps snow, rain, and ice off the boat.
  • Keeps sun off the gelcoat, upholstery, and canvas.
  • Puts the boat behind a closed door instead of in the open.

What it doesn't do is stop water in the engine from freezing. Winterize the boat before it goes in, just as you would for outdoor or covered storage. Our partner, Spokane Boat Repair, is a mobile marine mechanic that can winterize it for $420 plus tax per engine.

Indoor vs. covered vs. outdoor

OutdoorCoveredIndoor enclosed

Roof overheadNoYesYes
Enclosed with a doorNoNoYes

Covered storage costs less and keeps weather off the top of the boat. Indoor adds walls and a door. Pick indoor if you want the boat out of sight and out of blowing snow, and covered if a roof is enough.

The honest part about location

Some websites have described us as a Spokane storage facility. We're not. We're at 44300 State Route 25 N, Davenport, WA 99122, near the Fort Spokane boat launch on Lake Roosevelt, about 40 minutes from Spokane.

That's a benefit if you boat on Lake Roosevelt, because the boat is stored minutes from the launch. If you boat on lakes closer to Spokane, a lot in town may suit you better, unless you'd rather use our pickup and delivery and not tow at all.

Reserve an indoor unit

Call 509-282-5784, 7 AM to 7 PM, seven days a week. Have your boat's length, width, and height on the trailer ready. Access to the lot is 24/7.

Frequently asked questions

How much is indoor boat storage?

Our indoor enclosed units are $300–$500 a month. We have two sizes, 12x30 and 12x40. Call 509-282-5784 for the exact price on the size you need.

Are the indoor units climate-controlled or heated?

No. They're fully enclosed, but not heated or climate-controlled. Winterize your boat before storing it inside.

What size boat fits in a 12x40 unit?

The boat and trailer together have to be shorter than 40 feet from the tongue to the back of the motor or platform, and they have to fit through the door. Call 509-282-5784 with your measurements and we'll check.

Is your indoor storage in Spokane?

No. We're at 44300 State Route 25 N, Davenport, WA, near the Fort Spokane boat launch on Lake Roosevelt. Our All-Inclusive Winter Package includes pickup from Spokane, and pickup is available up to about 2 hours from our facility.

Is indoor storage worth it over covered?

Indoor adds walls and a closed door to what covered storage gives you, so the boat stays out of blowing snow and out of sight. Covered storage is $150–$300 a month and indoor is $300–$500. If a roof is enough, covered saves money.

Can I get my boat winterized before it goes in?

Yes. Our partner, Spokane Boat Repair, is a mobile marine mechanic that winterizes boats for $420 plus tax per engine. It's also included in our $2,200 plus tax All-Inclusive Winter Package.
