Carver 77017F-10 V-Hull Runabout Storage Cover, Haze Gray

If you're closing up a V-hull runabout for the season, the Carver 77017F-10 is the cover built to do it. It's cut to fit boats up to 17 feet 6 inches on the center line with a beam up to 90 inches, so it drapes over the cockpit, wraps the sides, and cinches down without leaving your gunwales exposed. Carver calls this a storage cover, and that's exactly what it's best at. Long stretches parked in the yard, tucked in a barn, or sitting on the trailer between trips.

The fabric is Poly-Flex II, a marine-grade woven polyester that Carver treats to shed water and stand up to the sun. Rain beads and runs off instead of soaking through. The weave breathes a little, so the air underneath isn't completely sealed off, which matters more than most folks think. A cover that traps every bit of moisture is how you end up with a musty cockpit come spring. This one's also finished to resist mildew and UV, the two things that quietly wreck a boat cover over a few seasons out in the weather.

Fit comes down to two numbers. Center line length and beam. Measure your boat bow to stern along the center line, then measure the widest point of the beam. As long as you're at or under 17 feet 6 inches and 90 inches, this cover has you covered. It's a styled fit for V-hull runabouts, so it follows the shape of the hull better than a flat tarp thrown over the top. That closer fit is what keeps it from flapping and chafing in the wind.

You get a motor cover in the box too, which is a nice touch. The outboard powerhead is one of the first things to take a beating from sun and rain when the boat sits, so having it wrapped up along with the hull saves you a second purchase. Carver also includes heavy-duty tie-down straps to snug the whole thing down. Run them under the hull and cinch them so the cover stays put in a blow.

One thing worth setting straight. This is a semi-custom cover sized by length and beam, not a boat-specific pattern cut for one exact make and model. That's what makes it flexible enough to fit a range of 17-foot runabouts, and it's why measuring your own boat matters. Get the center line and beam right and it sits clean. Guess at them and you'll either fight a cover that's too tight or chase one that's too loose. Two minutes with a tape measure saves you the headache.

A word on how to use it. This is a storage and mooring cover first. For long-term parking and light hauling around the ramp or the yard, the included straps do the job. If you're planning to tow this boat down the highway at speed on a regular basis, we'd add a few extra straps or a set of ratchet straps and pad any spots where the webbing crosses a sharp edge or slick gelcoat. Highway wind is a different animal than a boat sitting in the driveway. A little extra tie-down insurance goes a long way.

Care is simple. Let the boat dry before you cover it, prop the center up with a support pole or a similar prop so rain and snow shed instead of pooling, and pull the cover off now and then to let things air out after a wet stretch. Do that and Poly-Flex II will give you seasons of service. Haze gray is an easy color to live with. It hides dirt, doesn't show every water spot, and looks right on just about any hull.

Carver's been building covers and bimini tops for over 30 years, and they back their gear. If you've got a V-hull runabout in the 17-foot range that needs a proper cover for the off-season, the 77017F-10 is a straightforward, honest choice. Measure twice, order once, and your boat's protected.
