2018 MJM Yachts 34z
34z is ideal for a couple downsizing from larger power or sail: Still large enough a yacht to seat 3 couples in protected comfort and for safe passage in offshore waves, yet light and narrow enough for unassisted docking and single-handed operation. This is truly a powerboat that will keep people boating together through shared adventures on almost a daily basis.
The Express model offers an alternate styling with the opportunity to provide additional solid-glass protection for rougher water, higher speed operation while still have the flexibility to open up the sides, back and windshields for optimum control of ventilation. Apart from the design of these pilothouse side windows, the Downeast and Express models are alike.
Thanks to a beam of less than 12 feet, height with radar under 13.5 feet loaded on a trailer, and 10,600 lbs. ½ load displacement: 34z is large enough for comfortable offshore passage-making and cruising -- yet readily transportable by road (with permits) between a winter residence south and a summer vacation cottage north.
Twice the Fun on Half the Fuel
Cruising 25 knots (29 mph) at 2800 rpm with a 440 hp diesel, 34z burns only 12-14 gallons per hour while similar-size powerboats would be burning 20-30 gph. In an era of rising fuel prices, that is remarkable. Average fuel use over the course of several weeks is usually in the 4-5 gallons per hour range. $100 for the day instead of $200 on other 34-36 footers can be the difference between enjoying it and letting it sit in the slip.
A prop mounted close to a large rudder provides superior control when you need it most. BOATING Magazine (June ‘03) advised "...prop-powered boats track better (than jets) in most conditions, especially at slower speeds and particularly when running downsea.... If your cruising ground throws a lot of rough water at you, choose the props”. With bow and stern thruster, the 34z has comparable close-quarter maneuvering agility to the new IPS, AXIUS and ZEUS computer systems.
Reduced Owner Maintenance
Diesel mechanics say the 34z has the best engine access they’ve ever seen on any powerboat! The entire pilothouse deck rises 45 degrees on electric lifters. Side panels permit full access to either side of the engine. You can then step down from the cockpit to into either locker for checks or service. Wing fuel tanks are used to improve stability. Full-sized 26” mountain bikes may be stored hidden away in these lockers. Mesh bags organize hoses, shorepower cords, life jackets, etc. Deck drains capture rain and dew which then flow into the gray water system out through the transom rather than over the side through a gap in the toerail … streaking the topsides. The only exposed teak on deck is on the optional Adirondack stern seat which is protected by a snap-on vinyl cover when not in use.
