I bought this thinking, from both the title and the cover, that this was an encyclopedia on knots and how to make them. It's not. It's an overview of yachts and what you should have on them, and when and where knots are used. Now, I did get some interesting ideas while looking at the few illustrations, and learning the names of the knots, but overall this was not what I wanted in a book.
This is not a book for people who don't know yachts. By the time we got to baggy-wrinkle, I thought someone was pulling my leg. But no, it's a real thing that reduces sail chafe. Yeah, I don't know what I just said either.
I guess I should've guessed after the first chapter went into length describing different types of ropes, but I kept pushing through. By the halfway point I was skimming.
