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 30 T-Top Boat Cover — Premium Offshore Protection with SeaKeeper RIDE
The Jupiter 30 is a 29’6″ offshore center console with a 9’4″ beam, approximately 7,590 pounds dry, and power options up to 700 HP across twin or triple outboards. With 262 gallons of fuel, a resin-infused Posi-Stern hull featuring 24° of transom deadrise, and SeaKeeper RIDE stabilization as standard equipment, this is one of the most capable 30-class fishing platforms on the market. Jupiter Marine has been building premium offshore boats in Florida since 1989, and their commitment to performance, innovation, and build quality has earned a loyal following among serious bluewater anglers. Protecting that kind of investment starts with a custom-fitted cover from Jupiter boat covers — designed to match the precision of the boat itself.
Engineered for the Jupiter 30’s Advanced Layout
This cover is pattern-cut to the Jupiter 30’s specific dimensions, with reinforced cutouts that wrap around the T-Top support legs while leaving the hardtop roof fully exposed above. Every surface is protected — the helm with Garmin displays, Yamaha Helm Master joystick, leaning post, 40-gallon sport tournament livewell, rod lockers, and the full cockpit. The cover installs in under five minutes solo using the strap-and-buckle system and is reinforced for highway trailering. With 22 inches of draft (motors up), ramp access is clean and easy. For the next size up in Jupiter’s lineup, see our Jupiter 31 T-Top cover built for their legacy deep-V platform.
Fabric That Stands Up to Offshore Use
Choose 9oz solution-dyed marine fabric for 5–7 years of UV and weather protection, or premium Sunbrella acrylic for 8–10 years. Both are water-repellent, mildew-resistant, and double-stitched at every seam. A hem cord secures the cover at the rubrail, and adjustable tie-down straps lock everything tight. Each cover includes a 2-year manufacturer warranty. For Jupiter’s compact entry-level offshore platform, explore our Jupiter 26 T-Top cover built for the smallest boat in the fleet.
