Just wanted to take a second and share this link to the BoatTech articles on BoatUS. There are a lot of handy articles on topics like picking docklines, proper bilge pump installation and VHF basics to point out a few. Many but not all of the articles are written by Don Casey.
If you don’t have Don’s other books (see the Amazon link) you should have them. They are a great series, very straight forward and easy to read.
