Hardtops Are the Rage, but Canvas Tops Offer Advantages When it Comes to Cutting Weight and Saving Money

These days, you ain’t cool unless your boat’s got a hardtop. Indeed, among the new boats featured editorially in Sport Fishing during the past 12 months, more than 70 percent boasted hardtops, while around 13 percent sported canvas tops with permanent frames (as opposed to Bimini tops with fold-down frames). The remaining boats? Well, many were flats skiffs and bay boats without tops.


Boatbuilders and marine fabricators ­continually streamline hardtop designs and integrate new features, making these structures much more than places to retreat from the sun. But does that mean you should automatically opt for a hardtop on your fishing boat, be it new or an older craft? Not by a long shot. Canvas-top structures offer advantages of their own.

Cost Comparison

Whether you’re outfitting a center-console, dual‑console, walkaround cuddy, express or convertible, you’ll find a hardtop costs more than a comparable canvas-top structure. Most hardtops are fiberglass, with inner cores and gelcoat finishes on both sides. They often include complexities such as built-in electronics boxes, stereo speakers, LED dome lights and spreader lights. Some even have sunroofs and molded-in running lights.

Creating a top from canvas, on the other hand, is usually less expensive, even when undertaken by an expert canvas shop using top-quality Stamoid or Sunbrella marine fabrics. Still, most boat buyers gravitate to hardtops.

“Ninety-nine percent of our customers order hardtops,” says Ariel Pared of SeaVee Boats (seaveeboats.com), which offers both styles. “Customers like that you can almost seamlessly integrate features such as dome lights and stereo speakers into a hardtop,” Pared reveals.

“Many customers like the Key West-style tops with the narrower width in front to allow for vertical rod storage along the center-console.” For its 320 series — four models with LOAs measuring 32 feet, 5 inches — SeaVee lists a custom canvas T-top option for $7,100. The custom hardtop option lists for $10,800 — 52 percent more than fabric.

Hardtops cost more in the aftermarket as well, whether you are commissioning a customized top or considering a prefabricated universal top from a company such as Atlantic Towers or Fishmaster. To give you an idea, Atlantic sells its canvas WalkAround “Tee” Top — a prefab top for most cabin boats up to 25 feet — for $1,999, while the hardtop version retails for $2,499.


Weight Factor

Both types of tops usually have lightweight welded and anodized or powder-coated aluminum frames. Yet a canvas top saves weight versus a comparably sized top that’s constructed from fiberglass or other material such as a high-density polymer. A square yard of marine canvas weighs about a pound or two, while a square yard of fiberglass laminate tips the scales at 11 pounds or more.

This weight savings becomes a ­critical advantage on boats less than 25 feet in length or models with relatively narrow beams. Canvas tops help keep these boats from becoming top-heavy and rolling excessively. The same applies to convertibles and express models with towers. A canvas top over the second-station minimizes the mass aloft.

Reducing weight also helps improve fuel efficiency to extend fishing range, as well as on-road mileage while ­trailering a boat.

Longevity

Hardtops last longer than canvas tops. Even the best canvas ­eventually succumbs to UV, which leads to rotting and tearing, especially along the stitches and ­grommets. Canvas might endure for a decade or more, but a hardtop usually will last the lifetime of the boat. However, the canvas top itself is relatively inexpensive; you can usually replace the fabric two or three times for the extra cost of a hardtop.

In either case, maintenance helps ensure maximum longevity. Clean the canvas tops and spray them periodically with a water-repellent formula such as 303 Fabric Guard. Keep a coat of wax on fiberglass tops. And meticulously wash aluminum frames to get rid of salt residue and to prevent corrosion.
