What does gunter mean?
Gunter is a noun with two nautical senses. In specialist navigation usage, it denotes a logarithmic scale, usually realized as a marked rule whose sliding, graduated sections allow mathematical relationships to be read directly from the instrument. The older vessel sense refers to a shallow, flat-bottomed sailing barge, especially the type historically used on the Thames to transport bulk cargo. The two senses belong to different worlds: one is an aid to calculation and charting, while the other is a working boat. Both are now much less common in everyday speech than general terms such as scale or barge, and the vessel sense in particular sounds distinctly historical. Gunter remains useful to readers of maritime history, older nautical writing, and specialist technical prose, where its specific terminology distinguishes it from a generic scale or cargo boat. Its name also preserves a link with early modern English scientific and seafaring culture.
nounA gunter is a logarithmic scale used in navigation, especially one formed as a sliding rule. Historically, it also denoted a shallow, flat-bottomed sailing barge used to transport cargo on the Thames.
- A logarithmic scale, traditionally formed as a sliding rule, used for calculations in navigation.
- A shallow, flat-bottomed sailing barge, especially one historically used to carry cargo on the Thames.
"He slid the cursor along the gunter to estimate the distance between the two ports."
"The navigator adjusted the cursor on the gunter before plotting the ship’s course."
"A Thames gunter carried barrels of grain across the river."
The regular plural is possible but uncommon, as the word is usually encountered in the singular or in historical descriptions of vessels.
"Two gunters were moored beside the wharf."
A gunter is a navigator’s logarithmic shortcut, turning mathematical relationships into measurements straight from a marked rule.

Etymology of gunter
The word dates from the early 17th century and is generally linked to Gunter, the surname of the English mathematician Edmund Gunter, after whom a logarithmic navigation scale was also named. The related maritime uses developed in mathematical and shipping contexts, with the name applying both to the scale and to a shallow, flat-bottomed cargo barge used on the Thames. The vessel and instrument senses are therefore connected through the same historical namesake rather than through any literal relationship between a boat and a measuring device.
How gunter is actually used
The logarithmic-scale sense is specialist and now sounds archaic outside historical or nautical writing. The vessel sense is chiefly historical and strongly associated with river traffic on the Thames.
