I was looking at the Achievements on steam and saw The achievement Dogfight to win a multiplayer battle in the $200 fleet Limit Category. So I felt that making a ship that was under $200 that works, would be an interesting idea. So I'll show you what I came up with.
Gut Glück. :D
I am still in need of the multiplayer achievments. If you want to try your ships in multiplayer I'd like to help you with that :)
Do both of these ships only have a rifle?

gotta cut the corners somewhere
The second one also has a grenade, but I don't think a ship that small would be durable enough to make decent use of it. Grenadiers and other close-range ships tend to go down really quickly if they aren't properly armored.
