Twin engines, one job: make 9.5 metres feel settled at any speed.
The standard twin 6.2 litre MerCruiser engines on Bravo Three sterndrives carry the SLX 310 to a 45 knot top speed and a 25 knot cruise, with a twin 8.2 litre High Output option available for owners who want more in reserve. A deep V hull with six lifting strakes keeps her tracking cleanly through chop, and Sea Ray’s Quiet Ride system, a combination of sound insulation and vibration damping, brings interior noise down from 86 decibels to a measured 79. On a boat built for full days afloat rather than short blasts, that difference is felt in every conversation held at cruising speed.
She carries her size without carrying extra weight in the eye.
A deep V hull with 21 degrees of deadrise at the transom gives the SLX 310 her stance, Sea Ray’s design team drawing a profile that reads sleek rather than bulky despite the added length over the SLX 280. The electric folding watersports tower is standard, dropping flush for bridges and low marinas, and an optional carbon and Kevlar reinforced hardtop needs no extra support posts, which keeps sightlines from the helm genuinely open. At the stern, a swim platform deep enough to sit on while fitting a wakeboard, paired with a hinged sun lounge and its own storage, closes out a profile built around time spent at the back of the boat as much as the front.
The cockpit wraps all the way round, and nobody has to raise their voice to be heard across it.
A wraparound lounge with a swivel seat and a stowable table anchors the social deck, backed by a wet bar with a stainless sink, and an electric grill and refrigerator are available for owners who want to keep the galley above decks and the socialising in one place. Forward, the bow carries lounges with angled backrests and fold down armrests, reached through a walk through windscreen, with storage lockers keeping gear out of sight. A private head compartment, complete with running water and a 20 gallon holding tank, means guests are not left waiting for the nearest harbour, a genuine point of difference against open bowriders of similar length.
The helm has more in common with a modern wheelhouse than a bowrider dashboard.
Twin digital touchscreens, a 12 inch main display paired with a 7 inch secondary, replace the analogue gauges found on most boats this size, consolidating navigation, engine data, stereo, lighting and the watersports tower into one interface. An optional joystick docking system takes the guesswork out of close quarters manoeuvring, useful given her beam, and the standard Bravo Three sterndrives are built for the kind of repeated, everyday use a family day boat actually sees rather than occasional showing off. It is engineering aimed squarely at making the boat easier to own, not just faster to drive.
Two hundred nautical miles is a genuine day’s cruising, not a brochure number.
A 492 litre fuel tank, nearly 45 percent more than the SLX 280 carries, gives the SLX 310 her 200 nautical mile range at a 25 knot cruise, enough to cross open water between anchorages and still have margin for the return leg. That range matters more on a boat this size than raw top speed, since most owners spend the bulk of a day at cruise rather than at 45 knots. Paired with her deeper cockpit and private head, it is the range that lets the SLX 310 genuinely compete with boats a size class above her on long summer days rather than short afternoon runs.
