Rinker’s 310 is one of the best-selling cruisers in its range for good reason. For starters, it’s got more volume than most, with space for eight passengers — and their food, gear and supplies — on a weekend outing. Keep the party topside and you’re treated to a versatile aft lounge, which can morph from a traditional seat to a recliner or sun pad, a lengthy portside lounge that easily converts to a dinette or filler-equipped lounge, and a helm seat that can pivot and allow one more to join in on the socializing. On our rainy test day, the optional hardtop and standard camper canvas kept all of us dry. That top’s clear Lexan panels displayed a clarity not found in traditional isinglass. When the party’s over, divvy up to five passengers below between the forward V-berth, aft cabin and convertible salon settee. Brazilwood cabinetry, multiple generously sized portholes and an overhead skylight keep this cabin bright and airy. You’ll discover a low-maintenance fiberglass liner in the well-equipped head, and a fiddled, Corian countertop in the galley that looks great and keeps stuff from rolling off. You may not even need air conditioning. If the weather’s right, slide the screened companionway door closed and let the breeze blow in while keeping the bothersome bugs at bay.
