I found it very useful, the first time I attempted to invade britain I was turned back by a pirate fleet. Said pirate fleets tended to pop up every few turns and attempt to blockade my harbours, hence the need for a fleet to chase them off. I also found it useful in blockading any roman cities I was about to siege weakening roman infrastructure prior to a attack.

The fleet was about 6-8 ships and proved quite useful, but i suppose it could vary in usfullness game to game depending on how often pirates show up.
