Boat storage prices can be all over the place.
We’re talking $75 a month on the low end…and $350+ on the high end. That’s a HUGE gap. And most places won’t explain what you’re actually getting for those prices.
The cheapest option can cost you more in the long run: mold damage, cracked gel coat, ruined upholstery. But overpaying for storage you don’t need is just money you could’ve spent on the water.
Knoxville makes that decision even harder. With humidity sitting around 70% year-round, and mold only needing 60% to start growing, the wrong storage choice here isn’t just wasteful; it’s risky.
This guide breaks down:
- What each type of boat storage costs in the Knoxville area
- What drives those prices up or down
- The hidden fees most facilities don’t mention until you’ve signed
What Each Type of Boat Storage Costs
1. Outdoor Uncovered Storage: $75–$100/Month
You’re parking your boat on an open lot, gravel or paved, fully exposed to the elements. At Store Safe, gravel starts at $85/month, and asphalt starts at $90/month.
The tradeoff? Your boat takes the full hit from summer UV, spring pollen, and year-round humidity. A high-quality fitted cover is a must at this tier – without one, you’re looking at cosmetic damage that costs way more than the storage.
Best for: Trailered boats used frequently. Owners who invest in covers and regular detailing.
2. Covered Storage With Electricity: Starting at $130/Month
A roof overhead blocks direct sun and rain. But the real value here is the electrical hookup. At Store Safe, this option starts at $130/month.
That electricity lets you plug in a battery tender to keep your battery healthy during the off-season. For RV owners, it also allows you to keep air circulating inside during the hotter months, though you’ll want to check if extra electricity usage comes with an added charge.
Best for: Most Knoxville boat owners. Especially smart for boats with electronics or upholstered seating.
3. Indoor and Climate-Controlled Storage
Basic indoor gives you walls and a roof, but air isn’t regulated; temperature and humidity still swing with the seasons. Climate-controlled storage maintains consistent temperature and humidity year-round, protecting against warping, mildew, rust, and moisture damage.
At Store Safe, self-storage units start at $79/month and go up by size. Climate-controlled costs more, but when you’re protecting electronics, wood trim, or upholstered interiors…the math works in your favor.
Best for: Boats with sensitive electronics, wood trim, or leather/vinyl interiors.

What Drives the Price Up or Down
1. Boat Size and Type
This is the biggest factor. A 16-foot bass boat on a short trailer takes way less space than a 24-foot pontoon with a wide beam. Pontoons often need wider covered slips, which means higher rates.
Most facilities charge by linear foot, and they measure TOTAL length, which includes the trailer tongue and outboard motor in the down position. Even a couple of extra feet can bump you into the next price tier. Rates vary by facility, so it’s worth calling ahead with your full rig length to avoid sticker shock.
Quick tip: Measure bow to motor before you call any facility. That’s the number they’ll use.
2. Location Relative to the Lake
Just like real estate…location matters. Facilities right next to popular boat ramps and marinas near Fort Loudoun or Norris Lake charge a premium for that convenience.
Moving 10–15 minutes further from the water can save you meaningfully each month. Look for facilities in areas like Powell, Halls, or Fountain City, close enough to be practical, but not at lakeside pricing.
3. Season and Contract Length
Most boats come off the water between October and March. That’s peak storage season, and many facilities charge more during those months because demand is highest.
Signing a longer-term agreement usually gets you a lower monthly rate. But make sure you’re comfortable with the facility first. Some places lock you in with minimums that are hard to get out of. At StoreSafe, contracts are month to month, so you’re not stuck if your plans change.
Ask about: Whether they offer flexible terms that match your actual boating schedule.
4. Security and Amenities
Not all amenities are worth the extra cost. Here’s a simple way to think about it.
Worth paying for:
- 24-hour video surveillance
- Electronic gate access
- Well-lit, fully fenced lots
- Electrical hookups (for battery tenders and dehumidifiers)
Nice-to-have (but not essential):
- Wash stations
- Premium landscaping
- Concierge or valet-style launch services
Security and electricity are where your money makes a real difference. The rest is nice, but it shouldn’t be the reason your monthly bill jumps $50.
Hidden Fees to Ask About Before You Sign
That monthly rate on a website is rarely the full picture. Here’s what to watch for.
1. Setup and Admin Fees
Many facilities charge $25–$100 upfront for paperwork, gate codes, and deposits. Some waive these for longer commitments; it’s always worth asking.
2. Mandatory Insurance
If your policy doesn’t cover off-premises storage, expect $10–$30/month for additional coverage. Call your insurance provider first; adding to your existing policy is almost always cheaper.
3. Electricity Charges
“Electricity available” doesn’t always mean it’s included. Some charge $15–$25/month separately. Ask specifically: is electricity included, or billed separately?
4. Contract Minimums and Early Termination
Watch for 6–12 month commitments with exit penalties, low intro rates that bump up quietly, and auto-renewal clauses buried in the fine print. Read the contract before you sign.
5. Late Payment Fees
Late fees typically run $10–$30 or ~10% of your monthly bill. Some facilities also charge lien fees after extended nonpayment.
Bottom line: Ask for the TOTAL cost, not just the monthly rate. Add-ons can tack on $50–$100/month beyond the advertised price.
The Right Boat Storage Pays for Itself
Boat storage doesn’t have to be complicated.
Now you know what each type costs, what actually affects the price, and which fees to watch out for. That’s more than most boat owners figure out before they sign.
The only real question is how much protection your boat needs from East Tennessee’s humidity, UV, and freeze-thaw cycles. Match that to your budget, and you’re set.
Just remember…the cheapest monthly rate isn’t always the cheapest option. A little more per month now can save you a LOT in repairs later.
