The 2026 Deep Impact 399 Sport is a 40-foot center console powered by quad Mercury Racing 450R engines. Built on a proven twin-step deep vee hull, it combines offshore capability with a stable, dry ride. The boat features a 430-gallon fuel capacity and accommodates both serious fishing and extended cruising with a full cabin including air conditioning, a day bed, head, and galley sink.
The helm centers on dual 17-inch Garmin GPS displays paired with a Mercury 7-inch VesselView display, Garmin 315 VHF radio, and 1kW transducer with Garmin sounder module. Navigation and safety systems include a windlass, freshwater washdown, trim tabs, and comprehensive lighting throughout—ShadowCaster lights, spreader lights, multicolored under-gunwale and hardtop lighting, and LED underwater lights.
Onboard amenities span comfort and utility. The console cabin includes dual row helm seating with dropdown bolsters, a forward deluxe lounge, forward bow seating with backrests, and a transom seat. A summer kitchen features a sink and slide-out Yeti cooler. Four insulated 160-gallon fish boxes, recessed anchor locker, six bow storage lockers, and additional compartments throughout provide storage. Entertainment includes an Extreme JL Audio sound system, LED cup holders at the helm, and a recessed shower in the hardtop. A dive door with ladder and dual sunroofs complete the design. Fresh water capacity is 58 gallons.
