Custom Fit Boat Covers for Tideline Boats
Tideline builds something different: built-to-order fishing catamarans with a non-stepped twin-hull design that delivers a soft, stable, predictable ride in conditions that pound a typical V-hull. Sold factory-direct from North Carolina, models like the 235, 280 Bluewater, and 365 Offshore blend bay-boat versatility with serious offshore capability. A catamaran's wide beam and twin sponsons make a proper-fitting cover essential. Our custom Tideline boat covers are patterned to your exact model and year for a snug fit a generic cover simply can't match.

Tideline Boat Cover Features and Benefits
Cut to your exact Tideline model and year — including the wide beam and twin-hull shape — so the cover fits clean instead of bridging awkwardly like a universal cover.
Solution-dyed marine fabric stands up to offshore sun, salt, and humidity without fading, protecting your investment season after season.
A water-repellent finish helps rain and spray sheet off instead of pooling, while breathable construction limits trapped moisture and mildew.
Every Tideline cover is custom cut and sewn to order in the USA with reinforced seams, secure tie-downs, and a tailored fit.
About Tideline Boats
Tideline Boats builds built-to-order fishing catamarans, sold factory-direct out of North Carolina. Its signature non-stepped, planing catamaran hull rides on twin sponsons for a soft, stable, and predictable ride across a wide range of speeds and sea states — the kind of platform that stays comfortable when a single V-hull would be pounding. The lineup pairs the versatile 235 with the larger 280 Bluewater and the offshore-focused 365, the last designed by naval architect Robert Ullberg and built with 100% composite, vacuum-infused construction.
Why Protect Your Tideline with a Custom Cover?
An offshore catamaran is a significant investment, and the elements go to work the moment it stops running. UV fades gelcoat and upholstery, salt corrodes hardware and electronics, and standing water breeds mildew. A snug cover shields the console, helm, seating, and rigging on the trailer, at the slip, or in storage — protecting both condition and resale value.
Custom-Fit vs. Generic Covers
A universal cover sits loose, flaps at highway speed, and traps moisture against the gelcoat. Our Tideline covers are patterned to your specific model and year for a tailored fit that sheds water, resists wind, and stays put — a fit a one-size cover can’t deliver on a twin-hull boat.
Built for a Twin-Hull Catamaran
A catamaran’s wide beam, twin sponsons, and tunnel between the hulls give it a footprint nothing like a monohull — so a generic cover bridges, gaps, and flaps. We pattern to your exact Tideline model and configuration, including the T-top or hard-top, so the cover follows the cat’s shape cleanly and holds tight.
Features of Our Tideline Boat Covers
Each cover is crafted from marine-grade, UV-resistant fabric chosen to handle sun, salt, and humidity without fading or cracking. Reinforced stitching, tailored seams, and secure tie-downs keep it snug and quiet on the road, while a water-repellent finish helps rain and spray run off instead of soaking through.

Frequently Asked Questions - Tideline Boat Covers
What cover options do you have for Tideline boats?
We offer custom-fit T-top covers specifically for Tideline models, like the 365, to ensure maximum protection and a tailored fit.
How weather-resistant are your covers?
Our covers are crafted from water-resistant, UV-protected fabric that shields your boat from various weather conditions while preventing mildew and mold growth.
Can I tow my boat with the cover on?
Yes, our covers are designed to remain secure during transport, offering excellent protection against road debris.
How do I care for my boat cover?
To maintain the quality of your cover, use mild soap and water for cleaning, and avoid using harsh chemicals. For tough stains, use a soft brush and always ensure that the cover is dry before storing.
Can I leave the cover on while the boat is moored?
Our covers are designed for boats on trailers, lifts, or dry docks. We recommend removing the cover if the boat will be in the water for extended periods, to avoid potential saturation and damage.
Which Tideline models do you make covers for?
We make custom covers across the Tideline catamaran lineup — the 235, the 280 Bluewater, and the 365 Offshore. Tell us your model, year, and top configuration and we'll match the right pattern for your twin-hull boat.
Do you account for the catamaran's wide beam and twin hulls?
Yes. A cat's beam, sponsons, and tunnel are exactly why a generic cover doesn't work. We pattern to your specific Tideline so the cover follows the hull shape and sits tight rather than bridging across the tunnel.
My Tideline has a T-top or hard-top — does that change the cover?
It does. The top changes the shape the cover has to clear, and each configuration takes a different pattern. Let us know exactly how your Tideline is set up and we'll build the cover to fit it.
Are your Tideline covers made in the USA?
Yes — every Tideline cover is custom-made in the USA from marine-grade, water-repellent fabric built to handle offshore sun and salt.
