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
The World Cat 230 SD is a 22-foot 7-inch power catamaran with a Sport Deck layout — it combines the twin-hull catamaran ride with an open deck plan designed for versatility. The dual-hull design gives it an 8-foot 6-inch beam, 11-inch draft, and stability that monohull sport decks can't match. It runs twin engines rated up to 300 HP combined.
Yes. The cover is designed to go over the T-Top frame on the World Cat 230 SD. The pattern includes clearance for the hardtop structure while maintaining a snug, trailerable fit around the rest of the boat's catamaran hull.
The World Cat 230 SD has a wider beam and flatter hull profile than a monohull of the same length because of its dual-hull catamaran design. Our cover pattern is cut specifically for this catamaran shape — the wider beam, the tunnel between the hulls, and the unique bow profile are all accounted for so the cover fits without excess material.
Absolutely. The cover is built for trailering with reinforced stitching at every stress point. The 230 SD's 4,440-pound dry weight on its trailer won't cause any issues — the cover stays snug and secure at highway speeds.
The 230 SD Sport Deck has an open deck layout that prioritizes versatile deck space over the dual console arrangement of the 230 DC or the center console fishing focus of the 230 CC. All three share the same 22-foot 7-inch catamaran hull platform, but the SD's deck plan is designed for a mix of cruising, watersports, and light fishing.
We use solution-dyed marine fabric that resists UV fading, mold, mildew, and salt damage. Solution-dyed means the color is locked into the fiber during manufacturing — not applied afterward — so it holds up significantly longer than surface-dyed alternatives in saltwater environments.
Yes. The cover works whether your 230 SD is on a trailer, a dock lift, or in a slip. The catamaran's shallow 11-inch draft makes it ideal for dock lifts, and the cover fit stays the same regardless of your storage method.
Every cover ships with a free color-matched storage bag, free shipping anywhere in the continental US, and a 3-year fabric warranty covering defects in material and workmanship.
The catamaran tunnel hull gives the 230 SD a smoother ride in chop, better fuel efficiency than comparable monohulls, shallower draft for skinny water access, and a wider beam that creates more usable deck space. It's why World Cat owners specifically chose a catamaran over a monohull sport deck.
Yes. We offer this World Cat 230 SD T-Top cover in multiple color options including black, charcoal, and navy. All colors use the same solution-dyed marine fabric with identical UV resistance and 3-year warranty coverage.
World Cat 230 SD T-Top Boat Cover
The World Cat 230 SD is a 22-foot 7-inch power catamaran with a Sport Deck layout that blends the twin-hull catamaran ride with an open, versatile deck plan. Built in Tarboro, North Carolina, the 230 SD shares the same dual-hull platform as the rest of the 230 Series — 8-foot 6-inch beam, 11-inch draft, and stability that no monohull sport deck at this size can match. Our custom-fit T-Top boat cover wraps the entire 230 SD in solution-dyed marine fabric designed to handle years of UV exposure, salt spray, and coastal weather.
This cover is pattern-cut specifically for the 230 SD’s catamaran hull profile and Sport Deck layout. The wide catamaran beam, the open deck arrangement, and the T-Top hardtop frame are all built into the design. Reinforced stitching at every stress point handles the tension from covering a wide-beam catamaran, and the trailerable fit keeps the cover tight and secure at highway speed. The 230 SD’s 4,440-pound dry weight makes it easy to tow — the cover stays put.
Sport Deck Catamaran — Built for Versatility
World Cat engineered the 230 SD for owners who want catamaran ride quality in a layout that works for cruising, watersports, and light fishing. The tunnel between the twin hulls cushions wave impact, the shallow draft opens up skinny water, and the wider beam creates more usable deck space than any monohull sport deck at 23 feet. Twin engines rated up to 300 HP combined give the 230 SD serious performance on the catamaran platform.
Whether you keep the 230 SD on a trailer, a dock lift, or at a marina slip, this cover protects the gelcoat, electronics, upholstery, and Sport Deck layout from UV damage, bird strikes, pollen, and rain pooling. The catamaran-specific pattern means proper fit across the wider beam — no excess material flapping and no gaps where debris can get in.
