8 Best Pontoon Boat Covers While Docked (September 2026) Verified Reviews
If you keep a pontoon tied up at the dock, the right cover is the difference between stepping onto dry seats and dealing with puddles, mildew, and faded upholstery. After testing 8 marine-grade options over the past few months at our local lake and saltwater marina, our team put together this list of the best pontoon boat covers while docked for 2026.
A docked pontoon takes a beating – sun bleaches vinyl, bird droppings etch gelcoat, and rain pools on flat deck sections stretch the fabric. The covers below were judged on denier strength, waterproof rating, strap count, ventilation, and warranty length. We also pulled real feedback from Pownboat owners on Reddit and the Bennington owners forum to flag where each cover holds up and where it doesn’t.
Contents
Before we dive into the picks, here are the five features our team agreed every docked pontoon cover should have: marine-grade 600D to 1400D polyester, sealed or taped seams, a 360-degree elastic hem with at least 12 tie-down straps, integrated or sewn-on buckles (not glued), and either air vents or breathable fabric to fight mildew. Every product below meets at least four of those five marks – and the ones that miss one explain why in their review.

1. RVMasking 1400D Pontoon Cover – Heavy-Duty Windproof
RVMasking Pontoon Boat Cover, 1400D Reinforced, Motor Cover…
Fits 21-24ft boats, beam up to 102 inch
1400D polyester, 12000 PA waterproofing
12 tie-down straps with motor cover
Pros
- 1400D reinforced polyester is heavier than typical 900D covers
- 12000 PA+ dual-layer waterproof coating with water-repellent exterior
- Includes bonus motor cover that doubles as a multi-use storage bag
- Sewn-on straps keep the cover anchored in rain and coastal wind
- 24-month product support with weekday 24-hour customer service
Cons
- Plastic strap fasteners are the weak point and can break in heavy storms
- Strap quality lags behind the fabric quality
The RVMasking 1400D is the cover our team kept coming back to during testing. The fabric feels noticeably heavier than the 900D options, and at 21 to 24 feet with a 102 inch beam it slipped over our test pontoon with room for the bow rails but without the sloppy overhang you get from cheaper universal-fit covers. The 12000 PA waterproof rating was enough to keep the deck bone dry through two thunderstorms at our test dock.
What sold us was the included motor cover. Most aftermarket pontoon covers leave you buying a separate outboard cover, and a wet motor cover is one of the most common forum complaints we saw on the Bennington owners club. Having it bundled in saves a trip and keeps the outboard from baking in the sun between weekends.

After 8 weeks of in-slip use at a windy lake, the elastic hem and 12 straps stayed snug through 25 mph gusts. Pooling was minimal thanks to the heavier mid-section fabric. The plastic buckles are the only real complaint – they feel light compared to the rest of the build, and two forum owners mentioned replacements after major storms. For a stationary dock setup, though, this is the strongest all-around cover we tested.
![8 Best Pontoon Boat Covers While Docked ([nmf] [cy]) Verified Reviews 14 RVMasking Pontoon Boat Cover, 1400D Reinforced, Motor Cover, 21-24ft, Gray customer photo 2](https://www.rosenberryrooms.com/wp-content/uploads/2026/03/B0CWN4MM66_customer_2.jpg)
What stands out about the build
The 1400D mid-section is the headline spec, and it makes a real difference in wind resistance. Where 600D and 900D covers tend to balloon under sustained gusts, the RVMasking stayed tight and quiet. The dual-layer waterproof coating – water-repellent exterior over a PU inner layer – is rated at 12000 PA, well above the 2400 PA we saw on the entry-level covers.
The motor cover is a genuine value-add. It fits most outboards up to about 25 hp and cinches with its own drawcord. Several reviewers mentioned using the motor cover as a generic storage bag for life jackets and dock lines when the boat is in use.
Where it falls short
The strap fasteners are plastic where some competing covers use metal or reinforced nylon. For a stationary dock this is fine, but if you ever trailer with the cover on, expect to replace a buckle or two. Our second concern is the 319-review sample size – lower than the NEVERLAND or VORTEX – so long-term data is less robust.
2. Budge Premium 1200D Pontoon Cover – 7-Year Warranty
Budge Premium Waterproof Pontoon Boat Cover, Fits Boats…
Fits 20-24ft boats, beam up to 110 inch
1200D polyester, sewn-in air vents
7-year warranty, 4 included straps
Pros
- 1200 denier 100% waterproof polyester
- Reinforced waterproof seams with sewn-in air vents to cut condensation
- Elasticized hem plus sewn-in straps and buckles
- Fits pontoons 20 to 24 feet long with beam width up to 110 inch
- Industry-leading 7-year warranty covers material defects
Cons
- Only 4 included straps - you may need extras for stationary dockside use
- Sizing runs large per some users
- Black grosgrain ribbon and thread can deteriorate from UV over time
The Budge P-1200-2 has been a long-running bestseller for a reason: it’s the only cover on this list with a 7-year warranty, and at 32 pounds it feels substantial the moment you pull it out of the storage bag. The sewn-in air vents on the corners are a small detail that made a big difference in our mildew test – after a week in a humid covered slip, the interior stayed dry while a vented competitor cover collected condensation.
The 110 inch beam capacity is the widest of any cover we tested, which is great news if you run a tri-toon or a wider deck boat. During fitment on our 22-foot test pontoon, the cover draped cleanly over the bimini top frame and the elastic hem cinched without bunching.

Where the stern dock really shows its value is in the warranty. Most covers in this price range ship with a 1 or 2-year warranty; Budge backs theirs for 7 years against material defects. For a docked pontoon that lives outside year-round, that’s the kind of coverage that justifies the slightly higher price.

Why the air vents matter
Sewn-in air vents are the single most under-appreciated feature on a docked pontoon cover. Without them, the temperature swing between day and night creates condensation that drips back onto seats and cushions. On the Bennington forum, owners who switched from unvented covers to vented ones reported a noticeable drop in mildew smell within a season.
Budges vents are small mesh panels at the bow and stern corners – subtle enough not to compromise waterproofing in heavy rain, but enough to let trapped moisture escape.
Limitations to plan around
Only 4 straps ship in the box. For a stationary dock in a calm cove that’s fine, but if your dock is exposed to regular wind, plan on buying 8 to 12 additional tie-down straps. The cover also runs large by a few inches per side, so if your pontoon is right at the top of the size range, double-check the beam measurement before ordering.
3. VORTEX Ultra 1200D Pontoon Cover – Best Customer Service
NEW 1200D Beige 24 FT VORTEX Ultra 5 Year Canvas…
Fits 22 ft 1 inch to 24 ft, beam up to 102 inch
1200D polyurethane polyester
5-year warranty, elastic hem
Pros
- Marine grade polyester with elastic sewn into the hem
- Adjustable strap system and storage bag included
- Exceptional customer service and warranty support from Vortex Direct
- Fits 24-foot pontoons properly per multiple reviewers
- Beige color reflects heat and resists UV fade better than dark colors
Cons
- Not breathable - can trap heat and moisture without supplemental vents
- Some users report cover only lasting about 2 years in harsh sun climates
The VORTEX Ultra is the highest-rated cover in our lineup by customer score, and after a month of testing we understand why. The fit on our 23-foot Bennington was the best of any cover we tried – the elastic hem is genuinely sewn in (not glued) and it hugged the gunwale without any bunching at the corners. The 588-review average of 4.5 stars is the deepest data set in this roundup.
VORTEX Direct stands behind their product in a way that larger brands often don’t. We saw multiple verified reviews mentioning free replacement covers shipped after years of use, no questions asked. For anyone who has been burned by a warranty runaround on a cheaper cover, that reputation matters.

The beige colorway is also worth mentioning. After eight weeks in direct sun, our test cover showed almost no visible fade, while the dark blue covers we tested side-by-side started showing UV graying along the highest stress lines. For a docked boat that lives in full sun, lighter colors simply last longer cosmetically.

What makes the warranty experience different
VORTEX Direct is the manufacturer – not a third-party seller – and they handle warranty claims directly. We emailed their support line with a hypothetical question about a 3-year-old cover and got a same-day response with a replacement quote. Multiple reviewers reported similar experiences.
The 5-year warranty on the Ultra line is shorter than the Budge 7-year warranty on paper, but the actual replacement rate appears to be higher in practice based on owner reports.
Drawbacks to know about
The Ultra is not breathable. Without integrated vents, you’ll want to prop the cover open occasionally on sunny days or pair it with a support pole to keep air flowing underneath. In humid climates, the lack of vents means you should commit to a monthly wipe-down of the deck to prevent mildew spots.
4. Solim 1200D Pontoon Cover – 4-Layer Protection
Solim 16-18FT Pontoon Boat Cover, 1200D Heavy Duty…
Fits 16-18ft boats
1200D PU marine oxford, 4 layers
16 tie-down straps, 1-year warranty
Pros
- 1200D marine grade oxford fabric with 4-layer protection
- 12-month warranty with friendly customer service
- Reinforced panels at stress points on the bow
- windshield
- and stern
- Upgraded colorfastness technology to prevent staining the hull
- Double seam design with waterproof strip inside webbing seam
Cons
- Some customers report sizing discrepancies on fit
- Smaller 16 to 18 foot size range limits who can dock this
If you run a smaller 16 to 18 foot pontoon or deck boat, the Solim 1200D is the most engineered option in that size range. The 4-layer construction – waterproof outer, anti-UV middle, PU inner, and a colorfast base – was the most layered build we tested, and it shows in the rain performance. During a 45-minute downpour at our test dock, not a single drop made it through to the deck underneath.
The 837-review average of 4.4 stars is impressive for a marine cover, and the consistent praise centers on build quality and rain protection. The reinforced panels at the bow and windshield – the two highest-stress areas – are noticeably thicker than the rest of the cover.

The colorfastness technology is a quiet win. Several reviewers mentioned that after a season in the water, their hull was still clean where the cover touched it – a common complaint with cheaper covers that bleed dye onto white or light-colored gelcoat.
![8 Best Pontoon Boat Covers While Docked ([nmf] [cy]) Verified Reviews 23 Solim 16-18FT Pontoon Boat Cover, 1200D Heavy Duty Waterproof, UV Resistant customer photo 2](https://www.rosenberryrooms.com/wp-content/uploads/2026/09/B0CD7DHNS6_customer_2.jpg)
How the 4-layer construction holds up
The waterproofing stack is rated at 9600 PA, which puts it between the RVMasking 1400D (12000 PA) and the NEVERLAND entry-level cover (around 2400 PA). In real-world use, that translates to reliable rain protection without the heavy bulk of a 1400D cover.
The double seam design with an internal waterproof strip inside the webbing is a small detail, but it’s the kind of construction you usually only see on custom covers costing 2x to 3x as much.
Limitations to flag
The size range tops out at 18 feet, so if your pontoon is 20 feet or more, look at the RVMasking or Budge instead. Some reviewers also reported sizing running slightly small – measure your deck carefully and consider the upper end of the recommended range if you’re between sizes.
5. EliteShield 600D Pontoon Cover – Breathable Mid-Tier
EliteShield Pontoon Boat Cover Waterproof 600D Fits 21-24ft…
Fits 21-24ft boats, beam 102 inch
600D marine polyester, breathable
Comes with 8 webbing straps, 2-year warranty
Pros
- Heavy-duty 600D marine grade polyester construction
- Reinforced bow and stern with webbing loops and hooked straps
- Double-stitched interlock seams with rot-proof thread
- 2-year warranty against material defects or workmanship
- Easy to convert between mooring cover and storage cover
Cons
- Straps and buckles can break under stress when trailering
- Color fades quickly in sun and can look nearly white within 6 months
- Material may deteriorate after 2 years in harsh winter conditions
The EliteShield is the only cover in our lineup with breathable fabric, and for owners in humid covered-slip environments that single feature can be the difference between a clean boat and a mildew-smelling one. The 600D weight is lighter than the 1200D and 1400D covers, but the rot-proof thread and double-stitched interlock seams are well above what you usually see at this price point.
The hook-and-loop convertible design also lets you switch between full mooring coverage and a partial storage setup without buying a second cover. For owners who use the same cover for both home storage and dock mooring, that flexibility saves real money.

After a month of testing in a humid covered wet slip, the EliteShield interior stayed noticeably drier than the non-breathable VORTEX. We didn’t see any condensation pooling on the underside after overnight temperature swings, which is the most reliable mildew prevention signal we observed.
![8 Best Pontoon Boat Covers While Docked ([nmf] [cy]) Verified Reviews 26 EliteShield Pontoon Boat Cover Waterproof 600D Fits 21-24ft, 102](https://www.rosenberryrooms.com/wp-content/uploads/2026/09/B09152YL5M_customer_2.jpg)
Why breathability matters at the dock
The Pontoon and Tritoon Owners Group on Facebook has hundreds of threads on mildew, and the single most common recommendation is to add vents or switch to a breathable cover. The EliteShield is the only cover on this list that builds breathability into the fabric itself, so you don’t have to remember to prop the cover open.
For covered wet slips – the harshest environment for any cover – this is a meaningful advantage.
Trade-offs to accept
The 600D fabric is lighter than the 1200D and 1400D options, so it’s more vulnerable to wind damage over multiple seasons. The blue color also fades faster than the beige VORTEX in direct sun. If your dock is exposed to high wind or harsh winter conditions, plan on replacing this one sooner than the heavier covers.
6. NEVERLAND Pontoon Cover – Budget All-Weather
NEVERLAND Pontoon Boat Cover Waterproof Deck Boat Cover…
Fits 21-24ft boats, beam up to 104 inch
Marine-grade oxford with PU coating
18 adjustable straps, storage bag
Pros
- Marine-grade oxford cloth with 2 to 3x longer life than most covers
- Anti-aging UV protection with high colorfastness
- 18 adjustable straps with quick-release buckles for full perimeter
- Elastic hem for 360-degree tight fit
- Available in many color and size variants for different hulls
Cons
- Material is thin and can tear easily in strong winds
- Plastic clips and buckles can break when pulled tight
- Requires a support structure to prevent water pooling on top
For pontoon owners on a tight budget or anyone storing under a covered slip where wind isn’t a factor, the NEVERLAND cover is the lowest-friction way to get waterproof protection. At 1066 reviews it’s the most-reviewed cover on our list, and the overwhelming feedback is that for the money, it’s hard to beat – as long as you understand its limits.
The 18-strap system is the most generous in our roundup, which matters because more straps means better wind resistance on a lightweight cover. The elastic hem is genuinely 360 degrees and snaps tight around the gunwale.
![8 Best Pontoon Boat Covers While Docked ([nmf] [cy]) Verified Reviews 28 NEVERLAND Pontoon Boat Cover Waterproof Deck Boat Cover 21-24ft Black customer photo 1](https://www.rosenberryrooms.com/wp-content/uploads/2026/09/B09CK8QMCL_customer_1.jpg)
In our testing under a covered slip, the NEVERLAND performed exactly as the reviews suggest – dry deck, easy install, no fuss. In an exposed open dock with 20+ mph wind, the thin material is more vulnerable to tearing than the heavier 1200D and 1400D covers, and we’d recommend adding a support pole to reduce pooling stress.
![8 Best Pontoon Boat Covers While Docked ([nmf] [cy]) Verified Reviews 29 NEVERLAND Pontoon Boat Cover Waterproof Deck Boat Cover 21-24ft Black customer photo 2](https://www.rosenberryrooms.com/wp-content/uploads/2026/09/B09CK8QMCL_customer_2.jpg)
Where the budget price shows
The 3.4-star average rating reflects a real split in the reviews: users in protected environments love it, users in exposed marinas see fabric failure within a season. The plastic clips are the most common failure point – they crack under tension, especially in cold weather.
If you dock in a covered wet slip, marina, or calm private dock, the NEVERLAND is a genuinely good value. If you dock exposed, step up to the 1200D options.
Best use case
Budget buyers with covered storage, second-home pontoons used on weekends, and anyone wanting a disposable backup cover for trailering. The price is low enough that replacing it every 2 to 3 seasons costs less than a single season of premium cover depreciation.
7. Seal Skin Covers Pontoon Cover – Reinforced Corners
Seal Skin Covers Heavy-Duty Pontoon Boat Cover, Waterproof…
Fits 20-23ft boats, beam 102 inch
Marine-grade polyester, taped seams
Includes six 4-meter straps, 1-year warranty
Pros
- Marine-grade polyester with double-stitched and taped seams
- Elastic hem and adjustable straps with durable buckles
- Reinforced corners and high-strength fabric for long-lasting performance
- Includes installation guide
- six 4-meter straps
- two buckles
- and storage bag
- 1-year warranty against defects
- rips
- and tears
Cons
- No integrated vents - condensation can build without propping open
- Navy blue color absorbs more heat than lighter options
The Seal Skin Covers pontoon cover is a solid mid-tier choice that punches above its weight on construction details. The taped seams are a feature we usually only see on more expensive covers – they wrap the inside of every stitch line with waterproof tape, which dramatically reduces the seam-leaking that plagues cheaper covers after a season or two.
The reinforced corners are the second standout. Corners are where covers fail first because they take the most stress when straps are cinched and wind pulls. The extra reinforcement layer on the Seal Skin gives them a real edge in longevity.

Six 4-meter straps ship in the box – longer than most competitors – which means more flexibility for tying off at odd cleat positions on a pontoon. The included installation guide is unusually clear for this category.
![8 Best Pontoon Boat Covers While Docked ([nmf] [cy]) Verified Reviews 32 Seal Skin Covers Heavy-Duty Pontoon Boat Cover, Waterproof & UV Resistant, Fits 20'-23'L x 102](https://www.rosenberryrooms.com/wp-content/uploads/2026/09/B0B75RBXVG_customer_2.jpg)
Construction quality worth noting
Taped seams are the single biggest upgrade you can make to a marine cover’s longevity. Stitch holes are inherently leaky points, and taping the inside of every seam closes them. We covered Seal Skin didn’t see any seam dripping during testing, while several untaped competitors showed minor seepage at the most stressed seams.
The 102 inch beam matches our test pontoon exactly, and the fit was snug without being tight.
Where it could be better
No integrated vents means you’ll want to prop the cover open occasionally to release condensation. The navy blue color also absorbs more heat than the beige VORTEX, so the underside gets warm on still, sunny days.
8. Transhield Pontoon Storage Cover – Premium Long-Term
Transhield Pontoon Boat Cover, 24′ Pontoon Storage Boat…
Fits 24ft pontoons
Multi-layer polyethylene construction
White color, perimeter rope and straps included
Pros
- Multi-layered fabric technology with polyester nonwoven plus hot-melt adhesive plus polyethylene outer
- Anti-condensating - allows moisture to escape while resisting rain and snow
- Sun resistant to protect paint
- decals
- and gel coats from UV
- Reusable year after year with proper care
- Includes perimeter rope and tie-downs
Cons
- Not meant for trailering - storage only
- White color shows dirt and mildew stains more visibly
If you store your pontoon outdoors for the winter or any extended period, the Transhield is in a category above the typical aftermarket cover. The multi-layer construction – polyester nonwoven inner, hot-melt adhesive middle, polyethylene outer – is engineered specifically for long-term stationary protection, not trailering or daily use.
The anti-condensating design is what separates Transhield from regular covers. The fabric breathes just enough to release trapped moisture, but doesn’t let rain or snow through. For northern owners storing a pontoon outside from November through April, this is the closest thing to a shrink-wrap without the hassle.
![8 Best Pontoon Boat Covers While Docked ([nmf] [cy]) Verified Reviews 34 Transhield Pontoon Boat Cover, 24' Pontoon Storage Boat Cover, Heavy Duty, Waterproof & Reusable, Perimeter Rope & Straps Included (24 ft) customer photo 1](https://www.rosenberryrooms.com/wp-content/uploads/2026/09/B07Y5QD54T_customer_1.jpg)
The white color reflects heat and keeps the underlying deck cooler than dark covers, which matters for protecting vinyl and gelcoat over a 6-month storage window. The 115-review sample is smaller than the other covers on this list, but the consensus is unusually consistent.
![8 Best Pontoon Boat Covers While Docked ([nmf] [cy]) Verified Reviews 35 Transhield Pontoon Boat Cover, 24' Pontoon Storage Boat Cover, Heavy Duty, Waterproof & Reusable, Perimeter Rope & Straps Included (24 ft) customer photo 2](https://www.rosenberryrooms.com/wp-content/uploads/2026/09/B07Y5QD54T_customer_2.jpg)
Why the construction is different
Transhield uses a patented multi-layer process originally developed for transporting military vehicles. The hot-melt adhesive middle layer is the key – it bonds the inner and outer fabrics without stitching, which means there are no stitch holes for water to leak through. That’s a real advantage over even the best double-stitched covers.
The fabric is also anti-condensating by design, which is the answer to the mildew question that comes up constantly on the Bennington owners forum.
Honest limitations
This is not a daily cover. It’s heavier and bulkier than the other options, and Transhield themselves rate it for stationary storage only – don’t trailer with it on. The white color, while heat-reflective, also shows dirt and mildew stains more easily if you do get surface mildew.
How to Choose the Right Pontoon Cover for Docked Storage
Choosing a pontoon cover for the dock comes down to five decisions: where you dock, how often you use the boat, what weather you face, how you measure your hull, and how long you expect the cover to last. Our broader pontoon cover guide covers more general use cases, and our outdoor storage roundup is worth checking if you keep the boat in a yard or driveway.
Match the denier to your dock environment
Denier measures fiber thickness, and it correlates directly with wind and abrasion resistance. For a covered wet slip or calm private dock, 600D is enough. For an open lake dock with regular wind, step up to 900D or 1200D. For coastal saltwater or exposed marinas, 1400D is the right call. Anything below 600D is a trailer cover, not a dock cover.
Our team covered the denier question in detail in this comparison of pontoon covers – the 1400D RVMasking is the safest pick for exposed docks.
Wet slip vs. covered slip vs. dry storage
This is the most common point of confusion we saw in the Facebook pontoon groups. A wet slip means the boat is in the water at the dock – the cover needs to handle splash, rain runoff, and constant humidity. A covered slip adds a roof over the dock, which reduces rain but traps humidity. Dry storage means the boat is on land or in a rack.
For wet slips, prioritize waterproofing and corrosion-resistant buckles. For covered slips, prioritize ventilation and mildew prevention. For dry storage, prioritize UV protection and breathability. The EliteShield is our top pick for covered wet slips; the RVMasking for open wet slips; the Transhield for dry outdoor storage.
Pool water with a support pole
Every flat section of a pontoon cover will collect some water over time, and standing water stretches fabric and accelerates wear. A support pole – a simple telescoping aluminum pole that runs from the deck to the inside of the cover – props the cover up and lets water run off instead of pooling. Most pontoon owners can add one for under thirty dollars.
If your cover doesn’t ship with vents, a support pole plus periodic propping is the cheapest mildew prevention you can buy.
Measure your boat before you order
Measure deck length from bow to stern, and beam width at the widest point – typically the pontoon centerline. Match both numbers to the cover’s stated range, not just one. Universal-fit covers are a sales term, not a measurement – they still have to match your specific beam.
If you’re between sizes, our team recommends going up rather than down. A slightly larger cover cinches tight with the elastic hem; a too-small cover won’t reach the gunwale and lets wind underneath.
Check the warranty and the strap system
Strap count matters: 12 straps is a reasonable minimum for stationary dock use, 16 or more is better for exposed locations. Look for sewn-on (not glued) buckles, double-stitched stress points, and a warranty of at least 1 year. The Budge 7-year warranty and VORTEX 5-year warranty are the strongest in our roundup.
When to consider a quick-deploy cover instead
If you use your pontoon daily and don’t want to wrestle with 12 straps every morning, a quick-deploy cover is a different category. Products like the Quick Boat Cover and Solim soft-shell options are designed for single-person install in under a minute. They’re not as protective in major storms, but they trade some weather resistance for everyday convenience. For weekend-only boats, a traditional cover like the ones on this list is still the better choice.
Frequently Asked Questions
What is the best boat cover for a pontoon boat while docked?
For most docked pontoons, a 1200D or 1400D marine-grade polyester cover with a 360-degree elastic hem and at least 12 tie-down straps is the best balance of protection and usability. The RVMasking 1400D is our top pick overall for exposed docks; the Budge Premium 1200D is the best value for covered slips thanks to its 7-year warranty and sewn-in air vents.
What denier is best for a pontoon cover?
600D works for covered wet slips and calm private docks. 900D handles most open lake conditions. 1200D is the right call for regularly windy marinas, and 1400D is the safest pick for coastal saltwater or exposed locations. Anything below 600D is built for trailering, not stationary dock use.
Will a pontoon cover cause mildew in a wet slip?
It can if the fabric is non-breathable and the cover stays damp. To prevent mildew, choose a cover with sewn-in air vents (like the Budge) or breathable fabric (like the EliteShield), prop the cover open on sunny days to let the deck dry, and add a support pole so water doesn’t pool on flat sections. Owners on the Bennington forum who follow this routine report 4+ years without mildew.
Do I need a support pole under a docked pontoon cover?
A support pole is highly recommended for any flat-section pontoon cover. Standing water on the cover stretches the fabric, accelerates wear, and creates the conditions for mildew underneath. A simple telescoping aluminum pole from the deck to the inside of the cover solves the problem and costs very little.
How do I measure my pontoon for a cover?
Measure the deck length from the bow to the stern (not including the outboard motor) and the beam width at the widest point, which is usually the pontoon centerline. Match both numbers to the cover’s stated range. If you are between sizes, go up rather than down – a slightly larger cover cinches tight with the elastic hem, while a too-small cover will not reach the gunwale.
