✓ Category A Seaworthiness – There are about 1200 miles of potentially rough open water… 824 miles on the Great Lakes and 389 miles between Mobile and Clearwater… plus the Chesapeake, the Sounds in Florida and Carolinas, and Jersey Coast. I’ve seen a 4-day 30+ knot Westerly with mountainous, steep seas in the North Channel and a surprise 70-knot “white squall” on Lake Michigan. The MJM 40z is only one of two known vessels suitable for doing the Loop, between 30 and 50 feet that are ISO Certified Category A ‘Ocean”. The other is the new MJM 50z.
✓ IPS & DPS Managing of Locks –Volvo Penta IPS joystick docking and DPS (Dynamic Positioning System) allows you to go down the center of the lock. Stop. Use IPS to go to the wall. Then engage the DPS to hover next to the wall. You don’t have to be in a rush to grab lines. The DPS will keep the boat from slewing with the bathtub effect.. The flush deck from wheel to stern cleat makes it easy to grab a stern line without having to go up and down stairs or levels. See why the 40z maybe the easiest 40 footer to handle in tight situations: Solo Docking a 40z
✓ 10 Foot Air Height – With radar and a Glomex HD TV antenna, a 40z can do the Erie Canal route and has to wait for only 2 bridges of the 21 between Ft. Lauderdale and Palm Beach.
✓ Speed – There can be large distances between good marinas and anchorages. With 34 knot cruising speed, you can pick a weather window on the best day of the week to cover as many as 275 miles in daylight… rather than have to run overnight at 8 knots, be holed up for a week waiting in a less desirable anchorage, or risk having to be underway in all sorts of weather.
✓ Fuel Efficiency and Cost - Fuel efficiency is a function of horsepower applied to overcome resistance/drag. It takes more fuel to push a heavy boat. It is a myth spread by trawler builders that they are more fuel efficient. The only way to improve fuel efficiency is to build them lighter & stronger… of epoxy composites…like an MJM. At 8 knots, an MJM 40z gets 3.8 nmpg with a range of 1197 miles with 90% of its 350 gallon tank.. A Grand Banks 41 trawler at 8.8 knots gets 1.1 nmpg with a range of only 501 miles. You do the math on fuel cost for the 5,000 plus miles involved.
