Old Sport is a classic MJM 29 in very good condition with many upgrades including a new, 2026 Volvo Duo-Prop outdrive with a 2-year warranty. A 12-volt air-conditioning system was added in 2024, allowing for cold AC while underway or on the hook with NO need for a generator. Her low hour, D4 Volvo diesel engine is quiet, responsive and built to last. The MJM 29z is the only 29 footer in the world that can deliver such a fuel efficient but dry and comfortable ride. The cabin boasts 6-foot headroom - quite generous for a 29 footer.

Other upgrades include:

Garmin electronics package including GPS, Chart plotter, radar, autopilot and depth finder.

Bow thruster

Standard Horizon VHF

The 29z is a powerboat designed to be comfortable for bay cruising, fun and easy to drive, exceptionally seaworthy and dry, fast, and fuel-efficient. The reason we go boating is to get outdoors and enjoy the open air. The 29z accomplishes this by having Strata glass pilothouse side windows that zip up and are strapped in place. Additionally, as with all MJM Yachts, the front windshields hinge up parallel with the water for optimum ventilation and visibility. Notice that MJM's spotlights are mounted on the bow rail eliminating any reflection off the deck.

    "The MJM Yachts 29z (LOA 32.4’) is built without compromise and is the only boat in its class specifically designed to maximize fuel efficiency, with a leading edge, high-tech epoxy wet pre-preg Kevlar/E-glass/Corecell composite laminate, vacuum-bagged and oven-post-cured. This is a building method perfected over 25 years by Boston BoatWorks in building custom racing yachts, including America’s Cup contenders where cost was no object… winning was everything. It’s more costly, but of significantly higher quality. 29z is stronger and lighter than other boats built with conventional fiberglass or SCRIMP construction, primarily because epoxy has 3x the flexural strength of polyester or vinylester resins. Furthermore, 29z is certified by the International Standards Bureau in Brussels, Belgium as a CE Mark Category B Offshore Power Yacht."                                                                                                                                                  MJM 29z Brochure
