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.

Frequently Asked Questions
It's patterned for the classic 13'4" Boston Whaler tri-hull with a center console — either a factory center-steering boat like the 1971–1976 Sport or the Sourpuss, or a classic 13 an owner has fitted with a center console. It's not cut for the later 130 Sport or 130 Super Sport, which are different hulls.
It depends where your steering is. Choose this cover if the console sits on the centerline; choose the 13 Super Sport cover if your boat has the usual side console. The console position changes where the cover has to peak.
It can. Whaler redesigned the 13 hull and liner in 1971 and raised the transom from 15 to 20 inches in 1972, so the oldest boats sit a little differently at the stern. If you're not sure which generation you have, send us your year (the hull ID number on the starboard transom ends in the model year) and a couple of photos before ordering.
Choose 9oz solution-dyed polyester (Navy or Black) for heavy-duty everyday protection, or premium Sunbrella acrylic (Marine Blue, Black, or Smoke) for maximum UV resistance and longevity.
No. The cover is made to protect your boat while it is parked on its trailer, up on a lift or in storage. Take it off before you tow: trailering with the cover on can damage it and voids the warranty.
Materials and workmanship are covered for 1 year, and the fabric carries its own warranty (5 years on 9oz and 6 years on Sunbrella). Every cover is made to order, so please allow 1–3 weeks; shipping is a $30 flat rate within the continental US.
Pricing: 9oz $625.00 · Sunbrella $785.00 — your final total appears below as you build your cover.
⏱️ Current lead time: 1–3 weeks — every cover is custom-made for your boat.

Boston Whaler 13 Center Console Boat Cover — Custom-Fit for the Classic 13-Foot Whaler With a Center Console
The Boston Whaler 13 is the boat that started the company: Fisher-Pierce began selling it under the Boston Whaler name in 1958, and the 13-foot tri-hull stayed in production in one form or another for decades. Whaler’s 1998 catalogue lists the hull at 13’4″ overall with a 5’5″ beam (about 13’3½” by 5’3″ around 1960), weights from about 320 lb for the Standard to 410 lb for the Super Sport Limited, and a 40 hp maximum on wheel-steered models. Most classic 13s were built with a side console or tiller, but Whaler did build center-steering versions: the Sport with center steering and a narrow full-width console (1971–1976) and the Sourpuss (1971–1975), and many owners have since fitted a center console to their 13. This Center Console cover is patterned for the classic 13-foot Boston Whaler hull with a center console, and like all of our Boston Whaler boat covers, it’s cut to this hull rather than a generic 13-foot size chart.
How It Fits the Classic 13
The classic 13’s wide, flat tri-hull with its square bow is nothing like the pointed V-bow that generic 13-foot covers are cut for, so off-the-shelf covers tend to bunch at the bow and hang loose at the transom. This cover is cut to the 13’s footprint: it peaks over the center console and wheel, slopes down over the thwart seats and forward locker to the gunwales, and wraps the outboard at the transom so the whole boat sheds water as one drape. On side-console boats, order our 13 Super Sport cover instead. Installation takes about five minutes: drape it bow to stern, run the hem cord along the rubrail, and cinch the adjustable strap-and-buckle tie-downs. It’s made for storage on a trailer, lift, dry stack, or jet dock — take it off before towing, since trailering with the cover on can damage it and voids the warranty.
Classic 13 vs. Later 13-Foot Whalers
Whaler redesigned the 13 hull and liner in 1971 and raised the transom from 15 to 20 inches in 1972, and the later 130 Sport and 130 Super Sport are different hulls again. This cover is patterned for the classic 13’4″ Whaler; If you’re not sure which generation you have, send us your year (the hull ID number on the starboard transom ends in the model year) and a couple of photos before ordering.
Fabric, Warranty & Shipping
Choose 9oz solution-dyed marine fabric for heavy-duty everyday protection (5–7 year service life) or premium Sunbrella acrylic for 8–10 years of fade resistance. Both are water-repellent, breathable, mildew-resistant, and double-stitched at the seams. Each cover is backed by our warranty (1 year on materials and workmanship, plus 5 years on 9oz and 6 years on Sunbrella) and ships for a $30 flat rate within the US — every cover is made to order, so please allow 1–3 weeks. For side-console 13s, see the Boston Whaler 13 Super Sport cover; for the bigger classic, see the Boston Whaler 15 Center Console cover.
