A Garan merchant vessel was a type of starship utilized by Garan traders in the late 24th century.
Onquanii had such a vessel in 2376, which had subspace audio (and likely visual) communications, a cloaking device, and featured advanced transporter functions. Its armament was capable of disabling the weapons and shields of Federation Template:ShipClass starships. (VOY: "Warhead")
The designation of this vessel as being of Garan origin is inferred by Onquanii's captaincy of one, who himself is assumed to be Garan based on his makeup.
