Mates, Its a good guide. I would recommend purchasing the book and carrying it with you, the PDF is good for overview. It gives a great general overview.
The book is around 30.00
If you want all the nuts and bolts you need to take a gander at the CFR 46 AKA
Code of Federal Regulations. Rules and Regulations for Small passenger carrying vessels under 100 tons.
As with any government code book. Very dry reading but it breaks it all down.
Hoping to have my USCG licence in the next 4 weeks.
