Need some clarification

[Bear]

ok, here's the situation. I want to make a freelancer ID and IFF zoner gunboat. Now in my RP I want it to be home but also a work station for a small time escort service (escorting ships for you sick minded out there). Now the question. Can gunboats attack transports/freighters? I've heard of a rule that says that capital class ships can't attack transports/freighters and also in-game a message that pops up says that you can't intentionally ram a capital class ship gunboat or larger. Does this mean that Gunboats are classed as caps and can't attack freighters? The reason why I'm asking about freighters specifically is because A). I'm wanting to escort miners and most pirates that I've come across during my mining sessions are transports, and B). I know for sure that they can attack everything else (but you'd have to be an epic pilot to take on a battleship or cruiser solo, or just really slow minded).

Thanks for the posts in advance.
Bear.
