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.

Jupiter 34 T-Top Boat Cover — Flagship-Class Offshore Protection
The Jupiter 34 is Jupiter Marine’s largest center console — a 33’9″ offshore platform with a 10’5″ beam, approximately 9,880 pounds dry, and power options up to 1,050 HP across triple 350s or twin 450s. With 390 gallons of fuel, 50 gallons of water, SeaKeeper RIDE stabilization, and Yamaha Helm Master with joystick as standard, this is a no-compromise bluewater fishing machine. Jupiter’s Posi-Stern hull pad bottom with 24° of transom deadrise delivers the smooth, predictable ride that has defined the brand since Carl Herndon founded the company in 1989. Our custom-fitted T-Top covers protect every dollar of that investment, and Perfect Fit Boat Covers has been the trusted source for premium covers across the industry’s top brands.
