Dear 40z Owner:                         
 
Congratulations on becoming Captain and Owner of the world’s best built and most fuel efficient yacht of its size.  
The enclosed copy of the 40z Owner’s Manual should further contribute to your enjoyment and proficiency afloat.   
 
This manual was created jointly with Zurn Yacht Design, Boston BoatWorks and MJM Yachts.  Our experience 
with the first 102 boats (34z’s and 29z’s included) has been incorporated to make this manual as useful and relevant 
as possible. Keep in mind that there maybe some variances such as location of the breakers on the panel. And, from 
time-to-time we will change specifications to keep pace with changes made to improve the boat.   
 
When addressing a problem with a specific piece of equipment, this 40z Owner’s Manual is to be regarded only as a 
preliminary source of information. The equipment manufacturer’s own manual with trouble-shooting procedures, 
etc. is the primary source and authority. 
 
A National Marine Manufacturer’s Association (NMMA) publication 

Sportfish, Cruisers, Yachts 

accompanies, and 

forms part of, this 40z Owner Manual. This booklet has many universal handling and operating tips worth 
reviewing.  
 
This Owner’s Manual is designed to be a living document, not only for builder updates but for your own use and 
record. Each boat is provided with a copy of the current Manual organized in a STAPLES “Mini-Ring” type binder 
that allows you to add pages as needed. 
 
One of the great advantages of purchasing a series-built or semi-custom design is that owners have the benefit of 
learning from one another.  So, with your continued input and comments we can keep adding useful information and 
helpful hints to this manual. 
 
Part of the ISO CE Mark Certification Program is confirmation by the owner that the manual has been received.  
Please sign the extra page No. 3 included in the Manual as a receipt and return it in the stamped envelope provided. 
 
Best wishes for fair winds and sunny skies.   On behalf of the builder and designer, we are most appreciative, and I 
am particularly honored, that you have chosen the 40z.
