The expedition, including naturalists, botanists, a mineralogist, taxidermists, a philologist, &c., was carried by the sloops-of-war "Vincennes" and "Peacock," the brig "Porpoise," the storeship "Relief" and two tenders.
Sloops, fire - ships, bomb-vessels and royal yachts were said to be not rated.
Between 1738 and 1750 Manin and Sterlegoff made their way in small sloops from the mouth of the Yenesei as far north as 75° 15' N.
The land forces were supported by a river fleet consisting (in 1479) of 360 vessels, mostly sloops and corvettes, manned by 2600 sailors, generally Croats, and carrying 10,000 soldiers.
Sloops of an excellent type were built for work on the high seas, of which the celebrated "Kearsarge" was one.
