Takret starship
From Memory Alpha, the free Star Trek reference.
The Takret starship was a type of warp capable vessel used by the Takret in the 22nd century. It was probably capable of at least warp 7.
The starship that docked and boarded Enterprise in 2152 had three impulse engines on its back, and two nacelles coming out of its front. A roll bar also protruded from its top, as well as what appears to be two bussard collectors.
It was much smaller then Enterprise, and the Enterprise crew far outnumbered them. They probably only held about 15 people. (ENT: "The Catwalk")
