An owners manual written by the boat manufacturer is one thing but have you written a 160 page owners manual yourself specifically for your boat? Don't get me wrong, I think it is an amazing piece of work and I'd love to have one for my boat but it seems a bit excessive. I have a three ring binder full of manuals on my boat. It has the sketchy C&C wiring diagram for the boat in it and the engine manual as well as some winch and equipment manuals. Maybe I should higher this guy to make a custom manual for my boat
