2021 Formula 310 Bowrider

The 310 Bowrider is a dayboat full of versatility and style.

December 4, 2020

Formula updated its largest bowrider model with a new optional hardtop that really enhances this wide-beam dayboat’s versatility and style. We tested the sterndrive version of the 310 Bowrider—it’s also offered with outboard power—on a brilliant day that highlighted the hardtop option. A $34,580 upgrade, the fiberglass hardtop covers the main cockpit area and incorporates a skylight, four speakers and lights. For additional coverage over the aft lounge area, consider the optional power SureShade retractable sunshade ($10,690).

Most owners will use this boat for lounging and entertaining, and the 310 Bowrider is set in that regard. The boat is equipped with two cockpit tables, and a wet bar to port with a covered sink and space below for a 30-quart cooler or a pull-out Isotherm refrigerator ($2,340). There’s also built-in cooler below one of the bow seat cushions. The head compartment to port has 4 feet, 6 inches of headroom and, if desired, can be equipped with a shower.

Bow lounges have backrests against the consoles, and the center cushions lift out to create forward-facing seats. The aft cockpit features a settee to starboard, and a sun pad with pivoting backrest over the engine hatch. The rear portion of the sun pad lifts to reveal a dunnage box accessible from the 30-inch-deep swim platform. The helm features a double-wide seat with a backrest that can be pivoted to face aft for socializing. A Raymarine Axiom Pro 9 S chart plotter dominates the dash, with space for a smaller engine-specific multifunction display to its right. The helm is equipped with a wireless charging pad and one of the many USB ports sprinkled around the boat.

Twin 430 hp Ilmor 6.2 MV8 Ocean Performance Series engines mated the to Ilmor One-Drive system powered our boat. This was our first experience with the Ilmor One-Touch Pro joystick system ($30,395), and it proved itself when docking in gusting crosswinds. The progressive throttle control ramps up thrust in a linear fashion, and the hydraulic-shifting drives are smooth and quiet. The 22-degree hull slices through chop and banks confidently in turns like, well, like a Formula.
