I look at www.trawlerforum.com usually every day. Great resource. And there is a thread there pointing to this blog. I did a post a few days ago regarding some plumbing, and a member replied "You are getting plumbing and water schematics? Nice!"
Which took me back to my first hour aboard a Hampton Endurance. We were looking over the boat. I asked Scott Hauck some technical question and he replied "let's look at the owner's manual." Suffice to say I was blown away. A printed, and bound document, with every system, every specification, and information about every single piece of equipment. ("And we give it to you in a PDF too, of course.")
I have the PDF manual for a previous hull. I'll share a few pages of it here. I know this will be a much used resource on board.
In addition, the manual for every component is provided in several plastic boxes, all organized by manufacturer. With plenty of room for me to add as we add new equipment.
