Merchants hitting sub while submerged?

Naval guns accuracy can and will be addressed with a separate mod, no need to disturb TDW on it.

As for ranges at which enemy ship start firing their guns at us, anyone can decrease it by altering 'AI Cannons' or 'AI AA guns' 'Max fire range' in Sim.cfg. Unfortunately these parameters are global: they would be applied to ship to ship engagements as well, no matter their sizes or the effective range of their guns.
I am sure that IRAI's flexibility is what we need for dealing with this issue
