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.
*The warranty periods above are provided by the fabric manufacturer and cover the material itself. For details on what’s included in the warranty for your completed cover, please see our warranty page.

Frequently Asked Questions
It's patterned for the classic 15'3" Boston Whaler tri-hull with a center console, such as the Sport 15 Center Console Whaler built from 1982 to 1988, or a classic 15 that has been fitted with a center console. It isn't cut for the later 150 models.
It will drape over the boat, but the peak is placed for a centerline console, so a side-console 15 won't fit as neatly. Contact us with photos and we'll confirm the best option before your cover is cut.
Yes. The cover is cut to drape over the classic 15's railing and down to the rubrail, so the rails sit under the fabric rather than poking through it.
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.

Boston Whaler 15 Center Console Boat Cover — Custom-Fit for the Classic 15-Foot Whaler With a Center Console
The classic Boston Whaler 15 is the 15-foot version of Whaler’s foam-filled tri-hull, built from 1976 in Sport, Super Sport, GLS and commercial versions. Whaler’s 1984 catalogue lists the hull at 15’3″ overall with a 5’8″ beam and 8″ of draft, a bare hull weight of 500–550 lb, power from 20 to 70 hp, and room for five people. Most 15s were built with a side console, but from 1982 to 1988 Whaler offered the Sport 15 Center Console, with a molded center console (and a tunnel molded into the floor to it), a mahogany pilot thwart seat with a backrest and a wrap-around rail. This Center Console cover is patterned for the classic Boston Whaler 15 with a center console, and like all of our Boston Whaler boat covers, it’s cut to this hull rather than a generic 15-foot size chart.
How It Fits the Classic 15
The classic 15’s broad, square tri-hull bow is wider forward than a typical 15-foot V-hull, so generic covers bunch at the bow and run short along the sides. This cover is cut to the 15’s footprint: it peaks over the center console, slopes down over the pilot seat and forward deck to the gunwales, clears the wrap-around rail, and wraps the outboard at the transom so the boat sheds water as one drape. 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 15 vs. the 150 Models
Whaler’s later 150 Sport, 150 Super Sport and 150 Montauk are different, beamier hulls (about 15’4″–15’5″ with a 6’6″ beam). This cover is patterned for the classic 15’3″ Whaler with a center console; 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 the smaller classic, see the Boston Whaler 13 Center Console cover; for the bigger classic center console, see the Boston Whaler 17 Montauk cover.
