That is actually a great design Doom, good work. It looks very rouge-ish in Freelancer as those screens tell me. Much better than the current rogue gunboat, which would probably fit better as a Bounty Hunter gunboat.
Also, 6 guns is a good amount for a medium gunboat, such as that looks. I am just concerned about the coverage, with half the firepower on the top. Only two of the six guns could cover the bottom left and right of the gunboat. Maybe a little bit of a rethink on the gun mounts would be good, such as only one on the top, but two on the left side and right side, with one on the bottom. This is the only potential flaw I can see with your design. Good job Doom!
