Reddit reviews Shanties & Songs of the Sea

My favorite.

This one is also good if it's the one I'm thinking of.

You can find lots of other albums that are more stylized/modern, but I prefer traditional if I can find them. There are also lots of good books on amazon about sea songs. Check out the one by Stan Hugill. It's pretty authentic (dude is one of the last true chantiers who actually used this stuff as work songs on ships) and about as close to comprehensive as one book'll get you.
