IJN

So I have a theme for my IJN fleet.  Everything but the smallest ships
and carriers are battleriders.	They are all high thrust (6) and their
primary weapons are 1 arc p-torps.  Should be exciting to play.

We are running a campaign, one of our campaign rules is if tugs are
used the attacker must place them on the table.  So does anyone have
suggestions for IJN tugs?  I can attach the large engine modules to
whatever hull I use, but I need a base hull.  I'd sculpt it but my
sculpting skills are inadequate.

TIA
