To keep water from pooling on a boat cover, give the fabric a continuous downhill path to the outside of the boat. Start with correct fit and even tension, then support the low areas with equipment the cover maker allows. Tightening the straps harder will not reliably fix an oversized cover, a slipping pole or a flat pocket between high points.
The goal is a supported roof shape—not fabric stretched like a drum. A cover should shed rain without concentrating force on its seams, windshield, upholstery or attachment points.
The useful first purchase—and when not to buy it
If the cover fits but sags over an open cockpit, a compatible support system is a sensible starting point. The Taylor Made Boat Cover Support System #55741 combines a pole and webbing to support the cover across more than one small point. Check the exact cover, boat length, layout and attachment requirements before choosing it; it is not automatically the right system for a pontoon, T-top or every bowrider.
If the cover is the wrong size or cut, start with our boat-cover measuring and fit checklist. A pile of extra poles cannot turn the wrong cover into a fitted one.

Check the Taylor Made support system at West Marine. This listing specifies boats up to 22 feet and a 28–48-inch telescoping pole. Confirm the cover’s attachment points and support geometry; those dimensions are not a promise of universal fit or snow-load capacity.
Buy with realistic expectations: we have not hands-on tested this kit. West Marine’s live review panel showed 3.9/5 from 27 reviews when checked September 18, 2026. Feedback was mixed: some owners reported insufficient pole height or unstable support, while others found it effective on a compatible layout. Measure the height you actually need, check the return terms, and inspect the buckles and footing during setup. Treat it as one option to compare—not a guaranteed cure for every cover.
Find the reason water is collecting
| What you see | Likely issue to inspect | Useful correction |
|---|---|---|
| Puddle in the middle of an open cockpit | Unsupported span | Compatible pole, bows or webbing support |
| Pole leaning or sliding after rain | Unstable base, poor angle or loose adjustment | Correct base placement and locking method |
| Several loose pockets around the perimeter | Wrong fit or uneven tension | Refit the cover before adding supports |
| Water gathers beside a tall support | A ridge drains into another low pocket | Create an uninterrupted runoff path |
| Water underneath without a visible puddle | Leak, seam problem or condensation | Inspect the fabric, seams and ventilation separately |
Remove standing water without making the damage worse
A gallon of water weighs about 8.3 pounds. A large pocket can be much heavier than it looks. Keep people out from underneath loaded fabric, and do not stand on the cover or force a pole upward into a deep puddle.
From a safe position, remove the water gradually using a suitable siphon or small transfer method that will not damage the fabric. Do not puncture the cover to make a drain. If a seam, frame or attachment is failing, get help rather than trying to hold the load up by hand.
Once unloaded, inspect for stretched fabric, torn stitching and bent or cracked supports. A repeatedly stretched cover may need repair or replacement before the support layout will work properly.
Poles, bows and support straps: what each does
Support poles
A pole creates a high point. Its top must suit the cover’s reinforced pocket, snap, vent or approved contact area; its base needs stable, non-damaging footing. A sharp improvised tip can damage fabric. One very tall pole can still leave low pockets around it.
Support bows
Bows spread support across a wider span. They need compatible sockets or attachment points and enough clearance from glass and upholstery. Do not assume a flexible bow is rated to hold a heavy snow load.
Webbing-based systems
Webbing distributes support along the boat and can help keep the cover’s shape between supports. Taylor Made lists 50 feet of webbing, quick-release buckles, a pole and transom hooks for model 55741. Follow its instructions rather than attaching straps to convenient but unsuitable trim or fittings. See the manufacturer’s component description.
A practical setup sequence
- Check fit first. Center the cover and position reinforced areas correctly. Confirm that accessories and engine configuration match the cover’s intended application.
- Protect contact points. Use approved padding where specified; do not let a pole or cover bear on a sharp edge.
- Place supports. Build a gentle ridge or peaks that lead water outward without ending in a valley.
- Adjust tension evenly. Work around the boat instead of pulling one corner extremely tight. Follow the cover maker’s strap pattern.
- Check runoff. Inspect after ordinary rain or a gentle, controlled hose test. Do not blast fabric with a pressure washer.
- Recheck. Look again after wind, temperature changes and the first few storms; a slipping support may not be obvious when everything is dry.
Different cover styles have different hardware and installation rules. Use the appropriate document in Taylor Made’s cover installation library or the equivalent guide for your cover.
Three limits worth understanding
- Rain support is not snow-load certification. If freezing weather or snow is expected, use a storage arrangement expressly suitable for those conditions and inspect it safely.
- Storage use is not trailering approval. Road wind loads are different. The cover and its support system both need to allow the intended use.
- Dry-looking fabric does not mean a dry boat. Manage ventilation and existing moisture; a cover is not a repair for leaks or wet upholstery.
If the boat is laid up for the season, cover setup is only one task. Use our outboard winterization checklist for engine storage, and follow the boat maker’s drainage instructions. Never treat removal of a drain plug as an afloat practice.
Common questions
Can I just tilt the trailer higher?
Only within safe trailer support and manufacturer guidance. Changing the boat’s angle does not necessarily remove pockets in loose fabric. Never create an unstable trailer to compensate for a poorly supported cover.
Will waterproofing spray stop pooling?
No. A fabric treatment cannot create a runoff slope. Address fit and support first, then follow the fabric maker’s cleaning and treatment directions if water repellency needs attention.
How many poles do I need?
Enough approved support to eliminate unsupported pockets without overstressing the cover. Layout and cover design matter more than a universal one-pole-per-boat-length rule.
Bottom line: buy a support system to solve an identified low spot—not as a substitute for fit. A well-supported cover sheds water, stays clear of damaging contact points and remains easy to inspect.

For a compatible boat and cover, review the Taylor Made system’s current listing and fit details. Solve the fit and drainage problem first; buy support only where it addresses the actual low spot.
