How to Measure a Boat or Pontoon for Indoor Storage

Use this boat-and-trailer measurement checklist before comparing indoor storage. Check length, width, height, door clearance, and the turning approach.

By 404 Garage Condos & Storage

A boat advertised as 22 feet long needs more than 22 feet of storage. The trailer, motor, platform, and accessories can change the footprint. Before comparing indoor boat storage, measure the full rig in the condition you intend to park it.

1. Measure Overall Length

Measure from the front of the trailer tongue to the furthest point at the back, including the motor or swim platform. If your trailer has a folding tongue, record both lengths and confirm that folding it is practical in the unit. Do not assume an accessory can be removed or folded without checking its instructions.

2. Measure Width and Height on the Trailer

For width, include trailer fenders, guide posts, and anything extending beyond the hull. For height, measure from the ground to the tallest point while the boat is on its trailer. A tower, canopy frame, windshield, or cover support may be the highest point.

Write down the dimensions of the tow vehicle too. It needs room to approach and maneuver even if you will not store it inside.

3. Check the Clear Door Opening

A published door height is not a measurement of every usable clearance. Ask the team to verify the actual open height and width, including hardware or obstructions. At 404, published features include 14-foot overhead doors; the chosen unit still needs a fit check.

Compare your measurements with individual garage layouts. Leave room to walk around the boat, open storage compartments, disconnect the trailer, and close the garage door. A bathroom, stairway, or mezzanine support can change the parking position.

4. Check the Approach in Person

Walk the route from the gate to the unit. Discuss the turn into the door, backing angle, and room for the tow vehicle with Joe or Gary. Arrange any trailer fit check in advance rather than arriving unannounced at the private gated property.

5. Bring a Written List to the Tour

  • Boat and trailer overall length, width, and height.
  • Tow-vehicle dimensions and turning considerations.
  • Space needed for gear, shelving, batteries, and walking access.
  • Questions about access, heating controls, utilities, and insurance.
  • Any maintenance activities or stored materials that need use approval.

404 is at 1400 19th St NE in Sauk Rapids and offers garages for purchase. If you are comparing rental storage, use the ownership cost guide. If the boat travels between the metro and a cabin, also compare the Twin Cities–Brainerd/Baxter route.

Storage space does not include advertised winterization, transport, or repair services. Follow the boat and engine manufacturer’s storage instructions.

Is there indoor boat storage in Sauk Rapids that I can own?

404 offers heated garages for purchase that may suit a boat and trailer. Published layouts include 30 × 60 and 40 × 60 feet, with 14-foot overhead doors. Measure the full trailer length, tongue, motor, tower, and overall height, then confirm the exact door opening and usable floor space in the unit you choose. Heating does not replace your boat manufacturer’s winterization guidance.

What should I bring to a storage space tour?

Bring your vehicle or trailer measurements, a list of what you want to store, and any plans for shelving, a workbench, or a mezzanine. Joe or Gary can help you compare layouts and finishes. Ask for current availability, ownership costs, and the rules that apply to your intended use before deciding.
