when you dobble-click on a ship unit, you get a list, and all the info and statistic about that unit.
above there are or should be also details:
for example: Vaisseau de 64 (Heavy Warship)
688/688 Men - 0/0 Horses - 0/0 Canons
strange: a heavy warship withou canons....
it is only one example,... all other ships, even "don't carry cannons"
but there offensive and devensive fire is on full strange.
checks this please.
