MJM Yachts was founded in 2002 by Bob Johnstone, who 25 years earlier had co-founded J Boats, Inc., the leading brand of performance sailboats worldwide with over 12,000 sailing yachts on the water. Bob's focus on seaworthiness, performance and ease-of-handling carry over into MJM Yachts. The MJM 29z, MJM 34z, MJM 40z and the new MJM 36z (for 2011) burn approximately half the fuel of comparable boats their size while cruising at 25+ knots.

This “Made in the USA” innovation allows the 100+ owners of MJM Yachts to significantly lower their operating costs, while having a boat that’s more fun to drive on a daily, spur-of-the-moment basis. "Twice the fun, half the fuel!" has been MJM’s mantra from the beginning.
