MJM 40z & Nordhavn 40...Unique as 40's being IMCI Certified Category A Ocean

The International Marine Certification Institute (IMCI) certifies over 5,000 recreational vessels after survey of structural strength and offshore stability computations.  The highest level of certification is Category A Ocean, the next is Category B Offshore and then Category C for Coastal.

The MJM 40z is Category A. The 29z, 34z and 36z are Category B.

Only 5 well-known brands had vessels certified as Category A.  The vessels were the MJM 40z;  Nordhavn 40 and 47; Fleming 55, 65, 75; Tiara Sovran 58;  and, Marquis 420-720.   You can see the great contrast in design and displacement.  This following comparison makes the point that an exceptionally strong, light boat can be just as seaworthy as one of the heaviest boats... and more seaworthy than most of the so called "heavy" boats.

The Nordhaven 40 weighs 50,000 lbs. and cruises at 7 knots burning 2.6 gph at 1600 RPM with a range of 2200 miles from its 900 gallon fuel tank.

The MJM 40z weighs 21,000 lbs. and if cruising at 7.2 knots burns 2.05 gph at 1000 RPM with a range of 1100 miles from a 350 gallon fuel tank.  A 40z gives you the option to cruise at 34 knots burning 28 gph at 3400 RPM with a range of 383 miles

Designs from Hinckley, Sabre, Vicem, SeaRay, Hatteras, Viking, Ocean, Riviera, Hunt, Grand Banks, East Bay, Palm Beach, San Juan, Bertram, Back Cove, Azimut and Post were either Certified Category B or not listed as being certified at all.  None were Certified Category A.

55 Minutes - Stonington to Newport on the Newest 40z

It was the perfect powerboating Sunday!  Not a wind ripple on the water as we departed at 0917 from the Dog Watch Cafe at Dodson's Boat Yard in Stonington CT, which had been "Z" town over the weekend with three 40z's, ZING, WAVE DANCER &  SKIPPY;  three 36z's, BLUE DUCK, FIELD & STREAM & JOLLY ROGER and the 29z WANDERER.

As we cleared Watch Hill Light, Block Island Sound was before us as calm as I can remember.  We dialed up the speed to 34 knots, put ZING on autopilot and had a nice Sunday morning conversation.

Here's proof of the 34.3 knot speed, location and fuel efficiency of 1.2 NMPG achieved with the twin Yanmar 8LV's with 370 sterndrives on 40z #34... less than a week out of the yard at Boston BoatWorks.  Good job, team!

We'd just rounded Pt. Judith.  Here's a close up of the Raymarine e165. You can see the COG and Heading vectors putting us between Castle Hill and Beavertail.  Time is 1002 hours.  We were off Ft. Adams in the harbor by 1012... just as the seabreeze started to build out of Narragansett Bay.  By 1200 hours it was blowing 20+ knots out of the Southwest.   Sure pays to have the speed to take advantage of weather windows like that!  That 33 mile trip would have taken 4x as long in a trawler and catching some rough seas as well. 

Dogs Prefer MJM Yachts

A New York Times story on May 17 describes how wolves first became doglike by lingering around humans over the span of thousands of years.  It states, "Dog brains have become exquisitely tuned to our own".  Here is photographic evidence that the process may be occurring in less than a decade.  Dogs have discovered MJM Yachts and seem to be taking over.

"This is so easy, even a human could drive it."

MJM Yachts 40z... "Coolest" boat in July 5th Movie 'The Way, Way Back'.

"Mom, why do I have to wear that? "   Surely, a line for this Mother's Day in the preview of the forthcoming (July 5) movie, The Way, Way Back.   While reviewers may ultimately not give the movie more than one star * :  The inclusion of Brian Tedeschi's  40z PEYTON ROSE (renamed  BARELY A WAKE for the movie) in a prominent role makes it a five star ***** must see movie for the owners of such "cool" boats.  

Here's the write up and a link to the Preview. The Oscar winning screenwriters also produced the film Descendants.

“The Way, Way Back” is the funny and poignant coming of age story of 14-year-old Duncan’s (Liam James) summer vacation with his mother, Pam (Toni Collette), her overbearing boyfriend, Trent (Steve Carell), and his daughter, Steph (Zoe Levin). Having a rough time fitting in, the introverted Duncan finds an unexpected friend in gregarious Owen (Sam Rockwell), manager of the Water Wizz water park. Through his funny, clandestine friendship with Owen, Duncan slowly opens up to and begins to finally find his place in the world – all during a summer he will never forget.
