Additional information
Choose Your Cover Fabric
7 oz. Polyester — Our entry-level marine cover fabric, woven from 100% polyester fiber at a 7 oz. per linear yard weight. This lighter option keeps the cover manageable for solo handling while still delivering reliable protection against sun, rain, and debris. Backed by a 3-year fabric warranty. Ships in Black.
9 oz. Polyester — Step up to our heavy-duty polyester, engineered at 9 oz. per linear yard for boats that face tougher conditions or extended outdoor storage. The denser weave adds an extra layer of defense against abrasion and weather without adding unnecessary bulk. Protected by a 5-year fabric warranty. Ships in Navy or Black.
Sunbrella® — For boaters who want the best, our Sunbrella covers use 100% solution-dyed acrylic — the same fabric trusted by marine professionals worldwide. Naturally resistant to fading, mold, and water damage, Sunbrella holds its color and integrity season after season. Covered by a 6-year fabric warranty. Ships in Black, Smoke, or Marine Blue.
Both polyester options feature solution-dyed construction, where pigment is infused into each fiber during production rather than applied to the surface afterward. This process locks color deep into the material, preventing any dye transfer to your boat’s gel coat or finish. The result is a cover that stays vibrant without bleeding or rubbing off. Our polyester is also designed to breathe — it allows moisture trapped underneath to vent out naturally, reducing the risk of mildew and keeping your boat dry. The fabric holds its form without sagging or stretching over time, stays lightweight enough for one person to handle, and stands up to prolonged UV exposure and harsh marine weather.

Frequently Asked Questions
Yes — this cover is pattern-cut specifically for the Key West 203 center console hull. It fits the approximately 20-foot-3-inch length with 8-foot beam, wrapping over the center console and fully enclosing the outboard engine as one continuous piece.
No — the Key West 203 is a legacy center console model that predates the current 203 FS (Family Sportsman) designation. While the hull dimensions are similar, each model requires its own pattern-cut cover for a proper fit. Make sure to select the correct model when ordering.
The Key West 203 supports a single outboard from 115 up to 200 horsepower. Our cover fully encloses the engine as part of the continuous fabric drape past the transom, regardless of the outboard model mounted.
No — Key West transitioned from the standalone 203 to the 203 FS (Family Sportsman) and 203 DFS (Dual Function Sportsman) designations. The original 203 remains a popular pre-owned boat, and our cover continues to protect every model year produced.
We offer two marine-grade fabrics: our heavy-duty 9oz solution-dyed polyester (the most popular choice for durability and colorfastness) and premium Sunbrella acrylic canvas (lighter weight with exceptional UV resistance and breathability). Both resist mold, mildew, and fading.
Installation takes about 20 minutes with one person. Drape the cover from bow to stern over the center console, then secure using the included elastic hem cord and adjustable tie-down straps that buckle underneath the hull.
No — even though the hull numbers are similar, the 203 FS and the original 203 have different hull profiles. Using the wrong cover will result in a poor fit. Always select the exact model designation when ordering.
A center console mooring cover is a one-piece fitted cover that protects your entire boat while in storage. It shields the console, seating, deck hardware, and electronics from UV damage, rain, bird droppings, pollen, and debris — extending the life of your upholstery, gel coat, and onboard equipment.
Our 9oz solution-dyed polyester is the most popular choice — it is heavier, extremely durable, and offers excellent water resistance at a lower price point. Sunbrella acrylic is lighter, more breathable, and provides superior UV protection, making it ideal for boats stored in intense sun year-round. Both fabrics come with manufacturer warranties.
Select your boat model, cover type, and fabric choice on the product page, then add to cart. Every cover ships with the fitted cover, all necessary tie-down straps and buckles, a storage bag, and a detailed installation guide. Most orders ship within 5 to 7 business days.
Key West 203 Center Console Boat Cover (Legacy Model)
The Key West 203 is a 20-foot-3-inch center console that served as a versatile all-around fishing and family platform before Key West introduced the current 203 FS and 203 DFS designations. With an 8-foot beam and a dry weight around 1,900 pounds, this modified-V hull features approximately 19 degrees of deadrise, a single outboard between 115 and 200 horsepower, and roughly 50 gallons of fuel capacity. The 203’s balanced hull design made it popular among owners who needed a boat comfortable enough for family day trips yet capable enough for serious inshore and nearshore fishing.
Our custom-fitted mooring cover protects the entire 203 as one continuous piece of marine-grade fabric. The cover rises over the center console, slopes smoothly toward the stern, and extends past the transom to fully enclose the outboard engine with a natural, slightly loose drape. A hem cord cinches along the rubrail, and the bottom edge reaches nearly to the keel — leaving only a thin strip of V-bottom hull visible. Pattern-cut to the 203’s 8-foot beam and specific hull contours, this cover delivers water-shedding performance and wind resistance in any storage setup.
Legacy Model — Same Level of Protection
Although Key West has moved to the 203 FS and 203 DFS designations for newer models, the original 203 center console remains a popular pre-owned boat. Our cover protects every model year with your choice of heavy-duty 9oz solution-dyed polyester — the most popular option among boat owners for its exceptional durability and colorfastness — or premium Sunbrella acrylic canvas for superior UV resistance and breathability. Both fabrics are solution-dyed through the entire fiber, ensuring permanent colorfastness through years of sun and salt exposure.
Versatile Storage Protection
Whether your 203 lives on a trailer, boat lift, or dry rack, installation takes about 20 minutes with one person. The cover includes all tie-down straps, buckles, and hardware needed to secure it tightly underneath the hull, keeping it locked in place through trailering, storms, and seasonal storage.
