Generalized “How To” books are great pre-study learning
resources, but can be left ashore, once you’ve absorbed the general information. Specific information becomes much more useful, once offshore
In addition to the ubiquitous Owner/User Manuals
that come with equipment
, I like to have Shop Repair Manuals
Catalogues for all complicated/technical gear
I also carried a home made “Make Gord Smart” binder, c/w formulaes, conversions, and other technical details. This book also contained lists of “consumables” (specific to my boat), like filtre cross-reference numbers, belt sizes, etc. I also found it very useful to have a list of suppliers, c/w all contact information including the names of knowledgeable & helpful employees.
