Seamanship 19 - 21ft Waterproof Boat Cover

The Seamanship Trailerable Jumbo Boat Cover for 19–21ft vessels is built to take on Australian conditions head-on — from scorching summer UV and salt-laden coastal air to unexpected downpours and dusty inland tracks. Constructed from heavy-duty 600D marine-grade polyester with a UV-stabilised, water-resistant coating, this cover is engineered to protect your boat whether it's parked in the driveway, stored at the marina, or being towed down the highway behind your 4WD. The reinforced seams and robust buckle-and-strap system ensure a secure, rattle-free fit even at highway speeds, giving you complete peace of mind on every trip.

Designed specifically for Australian boating enthusiasts who fish, cruise, ski, and explore our rivers, lakes, and coastlines, the TJBC-1921-BK fits a wide range of trailerable runabouts, fishing boats, and ski boats in the 19 to 21 foot range. The jumbo cut accommodates higher bows, windscreens, and console setups that standard covers simply can't handle. Integrated support pole loops help shed pooling water, while the adjustable belly straps and bow and stern tie-down loops lock everything down tight for trailering. Keep your boat looking newer for longer and reduce costly UV and weather damage with this practical, durable all-season solution.
