But the Chiss had fought the Ssi-ruuvi fighters before and, even after years of technical improvements, they were capable of doing so again now. V'sett fighters, Jag soon discovered, were vulnerable to multiple attacks. Converging in pairs from different angles was difficult to coordinate without the benifit of effective comunications, but all the pilots read the situation similarly and they managed to struggle through. With a few multiple attacks under their belts, it got steadily easier, and in no time at all they were taking out V'sett fighters in sufficent quantities to make the Ssi-ruuk think twice. Soon the dense and volatile orbits surrounding Bakura were a mass of energy, dangerous for pilots on both sides to navigate through.
Seeing one of his squadron's X-wings trying to shake off the V'sett fighter riding his tail, Jag set off in pursuit. He got a lock on the fighter as it dog-tailed after the X-wing, and he fired when he thought he had a reasonable aim, but the fighter suddenly banked left after the X-wing and the shot went wide. Jag cursed under his breath as he brought the clawcraft back onto the fighters tail. Before he could line up another shot, two more fighters came at him from his port side, weapons blazing angrily at him. He sucked air through clenched teeth sharply and nosedived away from the incoming fire. Seconds later, when he had chance to look again for the X-wing, he saw it fall apart in a blaze of fire beneath the V'sett's blasters.
The two fighters he had just eluded were quickly back on his tail. With the rest of the squadron engaged in the battle elsewhere, he knew that help wouldn't be coming anytime soon. He was going to have to make his own luck...

The V'sset is, in fact, far more comparible to a Skipray Blastboat than any sort of fighter, simply because of Ssi-Ruuvi physique. If I recall correctly, they're five meters tall, on average - so it stands to reason that a "standard" fighter must be somewhat larger than a human-piloted fighter with similar abilities.

Catching sight of the nearer of Bakura's two moons, Jag pulled his clawcraft up and away, aiming with full throttle toward it. He didnt need to look back to know the fighters were following; the space ahead of him was puffing with bright explosions from their misfired shots.
He brought the clawcraft in steeply to the northernmost part of the moon, hoping to find some sort of cover that might help him evade his peruers. The closer he drew, the less likely this seemed. He brought his ship around from its almost perpendicular descent, speeding off across the surface of the moon. The ground was smooth and rolling, and looked to Jag to be made of an immense lava flow that had long since cooled. But it offered him no place to hide - and right now, that was all that mattered.
He jinked and swerved continously in a bid to avoid both fire and tractor beams, but he knew he wouldnt be able to keep it up indefinantly. He cursed himself again; this little maneuver of his had put him in a worse situation than he'd been in before!
Without warning, the surface of the moon dipped sharply ahead of him, and the smooth ground he'd been following became a motionless waterfall that poured into a huge canyon easily fifty kilometers wide and at least a couple deep. Crags appeared out of the shadows, along with large rocky outcrops that jutted from the walls of the canyon like crimson fists. The V'sett fighters followed efortlessly, no longer trying to shoot him out of the sky. They were obviously intent on capturing him now. They must have realized that eventually they would get him; they just had to be patient.

actually the average Ssi-Ruuvi is only 1.9-2.2 meters tall

just a note, im skipping a few paragraphs that mention Jag negotiating in a tunnel and the V'sett having no trouble keeping up.

He emerged from the spin battered and barely in control. The two V'setts on his tail negotiated the hail of debries and kept coming. He jerked his clawcraft from side to side in a desperate attempt to avoid their grasping tractor beams, but his collision with the rocks had allowed them to gain on him. It would only be a matter of seconds now before--
A white blur streaked up past his viewport. His sensors barely had time to register the Y-wingas it flew within meters of him, torpedo ports firing. The enemy Ssi-ruuvi pilots didnt have time to deactivate their tractor beams before they sucked in the proton torpedoes. One instantly exploded; the second took a hit that sent it spining wildly back to the surface of the moon, where it flowered in a brief and silent explosion.

In complete contrast, the two giant Sh'ner-class planetary assult carriers hung shining and impregnable above the battlefeild. Their impenetrable sheilds had repelled everything thrown at them, Clusters of captured ships of all shapes hung nearby, waiting to be processed. Denied the basic dignity of dying in battle, hundreds of pilots trapped in durasteel coffins had only entechment to look forward to.
A triangular formation of seven V'sett fighters accelerated over the horizon of the small moon, coming up hard on Jag and the Y-wing. Jag urged his clawcraft to gofaster, but it had given him everything it could. Seven fully armed ships against his damaged craft and the old Y-wing was a foregone conclusion.

The jamming ebbed long enough for him to check in on his squadron.
"Twin Suns, report!" He juked to avoid a crippling energy blast.
"Three here."
"Four."
"Six."
"Eight." There was a slight puase. "Jag, they've got me."
"And me," Six said.
"Looks like I'll have company, then," Three said. "They've got me too."
Jag cursed. Apart from himself, that just left one pilot free - and he wasnt sure how long he would last!
He watched with dismay as the Y-wing tried to dodge the incoming vessels, only to be jerked back in the clutches of seven combined tractor beams. The pilot went without a sound. Either her comm was down or she was sparing him her despair.
Jag vowed then and there that he would not share a similar fate. he would sooner blow his engines than allow his soul to be sucked out and squeezed into a battle droid. But how could he do that when there was a chance he and his pilots could escape? While there was life, there was hope.
Jag was so frustrated he wanted to scream to get it out of his system. he almost didnt feel the tractor beams as they wrapped around his struggling clawcraft and started to drag it back into captivity.

So, it has tractor beams.

This is definetly sounding like a Skipray or larger ship... are their any mentions of size in the books?

considering a carrier vessel carries as many of these as an average carrier would fighters I doubt they are on the range of skiprays.

no size is listed

Heavily decked out fighter from the sounds of it. My two cents is that it may be a few meters larger than the standard fighter but still smaller than a skipray.

Ok, using the above Mentions...
