This site drove me crazy. It has a very long list of words associated with ships and sailing, with only tantalizing clues as to meaning. I plan to spend a lot of time browsing there, but there is nothing clickable nor any clue as to where the "Dictionary" that is apparently being written can be accessed.

Gut I promise you, you will find it lovely browsing, if also frustrating.
