Day Yacht Overview: MJM 4’s Style, Comfort & Zones
The MJM 4 is a thoughtfully engineered 46’8″ day yacht that blends a Downeast-inspired pilothouse with modern outboard performance, offering a distinctive indoor/outdoor experience and an attention-grabbing profile finished in acrylic urethane topsides. At 12′ beam and a dry weight around 17,730 lb, she pairs a modified deep‑V hull (built vacuum‑infused with epoxy composite and closed‑cell foam core) and a 19:1 length‑to‑beam feel with practical features such as power opening forward windshields, panoramic windows and an integrated pilothouse that protects the helm while allowing seamless access to cockpit and bow. Whether tied to a marina dock in Jupiter, Florida or anchored for a day cruise, the boat reads as refined, stable and highly configurable for social life on the water.
Innovative Layout: Four Social Zones and Galley-Up
Designed around social use, the MJM 4 delivers four distinct zones — foredeck sunpad and seating, a protected pilothouse lounge that converts to berths, a generous aft cockpit with multiple table positions and an elevated galley-up serving bar — so hosts can circulate easily while guests relax or dine. The galley-up layout includes Corian counters, a two‑burner induction cooktop, microwave/convection oven, a two‑drawer 5.5 cu ft stainless refrigerator and a dedicated Indel freezer, all within reach of the aft entertaining area and the electrically operated serving bar with optional 120V electric grill; large windows, skylights and high‑gloss cherry cabinetry keep the interior bright, with convertible settees and a fixed island berth (78″ x 60″) below for overnighting.
Performance & Propulsion: Twin 600HP Verado Outboards
This example is equipped with the optional twin 2024 Mercury Verado V12 600 HP outboards (175 hours), delivering brisk performance and joystick docking capability; the published performance reference is around 50 mph top speed under appropriate conditions. Fuel capacity is 475 gallons for long runs, while shallow draft (approx. 2’1″ minimum) and a 3′ max draft make shoal cruising feasible. The hull’s dual lifting strakes, chine flats and 18.5–19° transom deadrise were conceived to balance a soft entry with responsive handling, and the propulsion system is supported by freshwater flushing, robust alternators and accessible service hatches.
Advanced Electronics: Garmin, Starlink and Joystick
Navigation and connectivity are comprehensive: twin Garmin 8622 22″ multifunction displays, Garmin Fantom radar (dome), Garmin VHF 215 with AIS receiver and AIS 800 transceiver provide integrated situational awareness, while joystick docking with GPS station‑hold (SkyHook) simplifies tight maneuvers; a high‑performance Starlink system with flat dish and onboard router keeps passengers connected offshore. Optional extras like Gyro stabilization and underwater LED lights enhance seakeeping and ambiance, and a bonded electrical system with Victron inverter/charger, Glendinning shorepower retractor and Victron batteries ensure reliable power management.
Comfort & Systems: HVAC, Galley, Heads and Plumbing
Comfort systems are sized for warm‑weather cruising and overnight stays: an optional 36,000 BTU two‑zone marine HVAC, a 13‑gallon Isotherm water heater (shore or genset), Seagull IV drinking water filtration and generous fresh water capacity support extended days aboard; the head features a Tecma toilet with a 39‑gallon holding tank and a separate shower stall with Corian surfaces and cherry storage. Practical plumbing and deck systems include a hot/cold shower on the swim platform, high‑pressure washdown, Marelon seacocks, 2000 GPH bilge pumps with alarm, and an ElectroSea CLEARLINE anti‑fouling option for raw water lines to reduce maintenance.
