Richard H. Dana, "The Seamans Friend," containing a treatise on practical seamanship with plates, a Dictionary of Sea Terms, Customs and Uses, etc.", first published in the 1840's, is invaluable. A reprint is available. The Dictionary portion was on line, but now access is forbidden (temporary?)
Darcy Lever, 1808 and many reprints, "The Young Officer's Sheet Anchor," (A key to rigging and seamanship). Useful for the early 19th c.

At the same Harvard website is a dictionary of sea terms, 1863-1870, which also is 'forbidden.' Temporary?

Admiral W. H. Smyth, 1867 and later printings, "The Sailors Word-Book"
This one has some 15000 entries on 750 pp., very useful for reference on the days of sail, but is more on 'Navy' than commercial sail.
