Sixth-rate

This is one of six ratings (1st, 2nd, 3rd, 4th, 5th, 6th) in the rating system of the Royal Navy.

Sixth-rate was the designation used by the Royal Navy for a small frigate, mounting between 22 and 28 nine-pounder guns on a single deck. Sixth-rate ships crewed about 150 and measured between 450 and 550 tons.

Sixth-rate was the lowest designation for a ship of the line. Smaller ships were called sloops; a larger sailing frigate would be fifth-rate.
