#1 · Best Overall

1. RVMasking 1600D Cover

• dimensions: 13.78 x 12.6 x 6.3 in
• Material: Polyester
• Compatible with Vehicle Type: Boat

Best for: Extra-Heavy 20–22-Foot Weather Cover.

Why it ranks #1: Fits 20–22-foot boats and specifies dual-layer waterproofing above 14,000 Pa, 1600D fabric, and 11 included straps.

A dual-layer waterproof treatment rated above 14,000 Pa is the defining specification of RVMasking’s 1600D cover for 20–22-foot boats. PU coating on both the exterior and interior adds water-focused protection, while the listing states a maximum beam width of 100 inches for fit checking.

The 1600D fabric is presented as a heavier option than 600D, 900D, and 1200D covers, with windproof performance cited alongside protection from scratches, dust, rain, and snow. Its dual-layer PU coating on the outer and inner surfaces carries a stated water resistance above 14,000 Pa, providing a specific benchmark for wet-weather storage. The listed fit is 20–22 feet by up to 100 inches wide, and 11 straps are included to secure the cover.

Skip it if you need an included storage bag; HAHASOLE lists one with its 20–22-foot cover.

RVMasking suits owners of 20–22-foot boats seeking a high stated water-resistance rating and 1600D fabric. Check that the beam stays within 100 inches; the included-components list specifies 11 straps.

#2 · Best Motor Cover

2. Kipiea 1300D Cover

• Material: 1300D High-Density Oxford Fabric, Polyurethane
• Compatible with Vehicle Type: Boat Covers 16-18.5ft

Best for: Boat-and-Motor Storage Set.

Why it ranks #2: Fits 16–18.5-foot boats and includes a separate outboard motor cover, storage bag, and 13 tie-down straps; it is not for highway towing.

An additional outboard motor cover is included with Kipiea’s 1300D boat cover, extending the supplied protection beyond the boat itself. Its double-layer PU waterproof coating and stated 16–18.5-foot fit make it a relevant option for V-hull, fish-and-ski, pro-style, fishing, and bass boat owners.

The 1300D high-density Oxford fabric and double-layer PU coating combine a specified heavy-duty material with added waterproof coating, supporting protection during storage. The separate outboard motor cover means buyers get a cover for the motor as well as the boat, while the storage bag helps keep the set portable between uses. Thirteen tie-down straps are included to secure the cover. This model is explicitly not for highway towing, and the supplied instructions say to remove it before trailering.

Skip it if you need a cover left on during highway towing; Mancro lists a trailerable 17–19-foot cover.

Kipiea is a fit for owners of compatible 16–18.5-foot boats who want a motor cover and storage bag in the set. Its boundary is clear: remove the cover before trailering, and do not use it for highway towing.

Listed on Amazon as: Kipiea 1300D Boat Cover – Heavy Duty Waterproof Boat Covers and Motor Cover, Double PU Waterproof, Fits V-Hull, Fish & Ski, Pro-Style, Fishing, Bass Boats (16'-18.5' Long X 94" Wide)

#3 · Best Sealed Seams

3. YimSting 1200D Cover

• dimensions: 16.93 x 12.2 x 7.48 in
• Material: Polyester
• Compatible with Vehicle Type: BOAT

Best for: V-Hull Sun-and-Rain Protection.

Why it ranks #3: Fits 16–18.5-foot V-hull boats, with all seams covered by waterproof tape and a stated water-pressure resistance above 6,000 Pa.

A three-layer PU backing rated for 6000+ Pa water pressure gives the YimSting cover a concrete waterproofing specification for 16–18.5-foot V-hull boats. Sealing tape covers every seam, while an anti-UV composite addresses sun exposure, pairing water-focused construction with protection against fabric ageing outdoors.

The 10.2-ounce, 1200D marine-grade polyester is combined with a three-layer PU backing, giving buyers both a heavy-duty fabric specification and a stated water-pressure rating. Waterproof tape across all seams targets another potential water-entry point. Its anti-UV composite is specified to help prevent ageing, disintegration, and tearing from sun exposure. The cover is listed for 16–18.5-foot boats, and the setup video can guide installation; the included components list contains the cover itself, not straps.

Skip it if you need included tie-down straps; NEVERLAND lists adjustable buckle straps with its 20–22-foot cover.

This suits V-hull owners with boats from 16 to 18.5 feet who value stated water-pressure resistance and seam sealing. Account for the included-components list, which names the cover itself rather than straps, when planning installation.

#4 · Best Reinforced Corners

4. HAHASOLE 1200D Cover

• dimensions: 16.2 x 13 x 7 in
• Material: 1200D PU
• Compatible with Vehicle Type: boat cover

Best for: Reinforced 20–22-Foot Storage.

Why it ranks #4: For 20–22-foot boats, it combines 1200D PU fabric, waterproof seam strips, double stitching, and reinforcement at front, middle, and rear corners.

Waterproof seam strips over the webbing seams are the HAHASOLE cover’s key detail, helping limit seepage at stitching points on a 20–22-foot boat. Double stitching and added reinforcement at the bow, middle, and rear corners add protection where the cover is most exposed during storage or transport.

The 1200D PU material pairs with bound, double-stitched seams and waterproof strips, addressing both fabric durability and water entry through joins. Reinforcement at the front, middle, and rear corners helps shield those high-stress areas, while the included adjustable straps let you secure the cover around the boat. Its listed fit is 20–22 feet; check your boat’s dimensions against that range before choosing it. A storage bag is included for keeping the cover together between uses.

Skip it if you need a stated maximum beam width; YimSting specifies a 16–18.5-foot V-hull cover instead.

For owners of 20–22-foot boats who want seam-focused water protection and reinforcement at key areas, this HAHASOLE cover merits consideration. Its listed details do not give a beam-width limit, so verify the boat’s measurements before selecting it.

5. Tuszom 1600D V-Hull Cover

• Material: Polyester
• Compatible with Vehicle Type: V-Hull Boat,Tri-Hull Boat,Runabout…

Best for: Reinforced V-Hull Wear Zones.

Why it ranks #5: Its listed 17–19-foot V-hull fit and 12,000 Pa waterproofing are paired with five-layer fabric and reinforced bow and stern areas.

Tuszom uses five-layer 1600D fabric in the high-stress middle section, paired with five-layer 1200D fabric elsewhere, for its 17–19-foot V-hull cover. Double-thickened bow and stern areas target wear and tearing at sharp edges, making its construction especially relevant to boats with exposed contact points.

The fabric layout concentrates five-layer 1600D material in the middle, with five-layer 1200D across other areas; the center material is specified at 650 lbf tension strength. That stepped construction gives buyers a clear account of where heavier fabric is used. Double-thickened bow and stern sections target sharp-edge wear, while the stated 12,000 Pa full-cover waterproofing addresses rain protection. The listing includes V-hull, tri-hull, runabout, fishing-ski, pro-style, and bass boats among compatible types.

Skip it if you need a stated beam-width limit for a 20–22-foot boat; RVMasking lists a 100-inch maximum.

This Tuszom cover suits owners of compatible 17–19-foot hulls who value heavier fabric in the middle and reinforced bow and stern sections. Confirm that your boat’s dimensions fit, since no maximum beam is stated.

Eleven adjustable straps with quick-release buckles give the Mancro cover a practical securing system for its listed 17–19-foot trailerable-boat use. Marine-grade fabric with waterproof and UV-resistant coating adds weather protection, while an elastic cord is specified to help create a snug fit around the boat.

The adjustable 11-strap arrangement and quick-release buckles make the cover easier to put on and take off, while providing multiple points for securing it. An elastic cord works alongside those straps to support a snug fit. Marine-grade fabric with waterproof and UV-resistant coating addresses exposure to rain and sun, and two-thread stitching contributes to seam construction. The listed fit is 17–19 feet; compare that range and the cover’s dimensions with your boat before use.

Skip it if you need a stated beam-width maximum; RVMasking lists a 20–22-foot cover for boats up to 100 inches wide.

Consider Mancro if your boat is 17–19 feet and you want adjustable straps, quick-release buckles, and an elastic fit. The listing does not state a maximum beam width, so check that the cover’s dimensions suit your hull.

Why it ranks #7: For 17–19-foot boats, it lists 1200D Oxford fabric, PU coating rated to withstand 6,000 Pa, and reinforced bow and stern sections.

Kayme’s 1200D Oxford cloth combines a marine-grade waterproof PU coating rated to withstand 6000 Pa with a UV-resistant coating. For owners of 17–19-foot boats, that pairing addresses water entry and sun-related fabric ageing, while thickened bow and stern sections target areas prone to wear.

The 1200D Oxford fabric is specified as more tear-resistant than 900D and 600D Oxford, and the PU coating is rated for 6000 Pa water pressure. Together, those details help buyers assess the fabric and its stated resistance to water. The UV-resistant coating is intended to help prevent ageing, disintegration, and tearing from sunlight. Thickened bow and stern areas add reinforcement at wear points. The listed fit is 17–19 feet, but no maximum beam width is supplied.

Skip it if you need a listed strap set; RVMasking specifies 11 straps for its 20–22-foot cover.

Kayme is suited to owners of 17–19-foot boats storing them where sun exposure and water protection matter. Its fit details do not give a beam-width maximum, so confirm the cover dimensions work with your hull.

A stated capacity for boats up to 102 inches wide distinguishes NEVERLAND’s 20–22-foot cover for owners of broad-beam hulls.

Best for: Compact 12–14-Foot Reinforced Cover.

Why it ranks #10: Its 12–14-foot size, four-layer PU coating, double-needle stitching, and reinforced bow and stern suit smaller boats, but listed fit detail is limited.

Four-layer PU coating and reinforced seams give the LumiCalyx cover a layered waterproofing approach for smaller 12–14-foot boats. Double-needle stitching adds reinforcement at the seams, while extra layers at the bow and stern corners target common wear points where tearing can compromise long-term cover use.

The premium Oxford cloth’s four-layer PU coating is paired with a claim of 100% waterproofing and UV protection, addressing both wet and sunny storage conditions. Double-needle stitching and reinforced seams add tear resistance at joins, while extra reinforcement at the bow and stern corners focuses protection on typical wear areas.
