yeah i myself was thinking of a ship with 3 light guns pointed on either side and how it could be different from any of the current ships that rely on broadsiding like the galleon or junker, while still being fun to use and fight against. Note My idea of how a ship set up like that should work IS VERY DIFFERENT FROM YOURS.
First i understand with how you could make there be no blindsides by using 6 light guns but i think that is a bad idea as it makes the ship very frustrating to fight and counter. Plus it the light guns themselves would not overlap 360 divided by 6 is 60 degrees per light gun to cover which is the largest radius for the light guns to have so you cant fire them together. I think it would be best to have the 3 light guns be bearing 90 and 270 on the ship respectively to give it ( if you don't understand bearing 0/360 is the front of the ship 90 is to the right 180 is behind 270 is to the left, just like a compass only referencing the sides of the ship instead of north south east and west, ex bearing 75 would be pointing right and slightly forward)
I do not like the idea a a feeble and fragile broadsider ship either as it would get shredded by sniper ships before it could get close, so making the ship durable like a galleon would be better, in my opinion.
To further distinguish it from its broadside counterparts which are both slow making this ship fast and heavy gives it its own unique playstyle of a ship that can truck along at a very good pace and hit like a truck when it rams something, but does not have guns on the front to soften the target before ramming (I'm not talking very fast like squid fast here but faster than galleon or junker and perhaps with amazing acceleration for its weight to emphasize this aspect).
since light weapons are harder to disable than heavy and already have better arks of fire it would be hard to get out of this ships broadside when you are in it, and since it is a ramming ship the front could potentially be dangerous as well. Two ways to mitigate these issues and stop the ship from being over powered would be to move the main engine form the back and to give the ship atrocious turning. Moving the main engine underneath the front of the ship with a little ramp down for the crew to repair it makes it visible when the ship is trucking right at you so some well placed shots could destroy it and their ability to ram and kill you while also making the ship more unique by having it protected if you got behind the ship so it can still run away at a good pace if it cant get the turning engines working to bring it guns to bear. As for giving it atrocious turning well as previously mentioned light guns are harder to keep disabled due to quick rebuild times and having 3 on each side makes it damn near impossible to stop all of them from shooting so giving the ship itself very bad ability to turn helps ships stay in its small blind spots and get the kill against it.
TLDNR: HOW I IMAGINE A SHIP LIKE THIS SHOULD WORK
Features:
guns are bearing 80, 90, 100 and ,260, 270, 280 giving it blindsides in the front and back and hopefully reducing the merc issue.
Main engine is below and on front part of the ship making it protected if a ship gets behind it, but can be destroyed by ships infront of it ie. the ones its trying to ram.
large narrow target making it harder to hit when coming at you but easy to snipe if its trying to broadside
Advantages:
+durable
+fast and heavy so great for ramming
+great acceleration
+very destructive broadsides
Disadvantages
-very poor turning
-blind sides infront and behind
-balloon, turning engines, main engine, and hull are far apart from each other on such a long ship.
-very poor vertical performance giving other ships another way to get out of its broadside arcs.
How i think it should look:
giving it an Asian influence like the goldfish and having the metal ramming part on the front of the balloon look like metal dragon head would be cool.
