I've given the lantern quite some consideration, and the current one is the one that has worked best. I used the type with the transparent cheese slopes in my previos ship the Pallas, but never really liked it as it looked too boxy. As far as the other design is concerned, the one with the inverted cone, it looks very realistic but it also looks too big on this ship- I think it is more in keeping with a galleon design ( even though the Diomedes has six middle sections!). If anything it gave the ship a comical look. I have also considered using just a larger radar plate for the top to give the lantern a more conical look, but again it doesn't really look right.
