How does Naval force limit work?

[Halaberiel]

I'm playing as Portugal and my limit is currently 1426 in 1741 and I'm not sure why. My limit just keeps going up and up, I've never had anywhere close to this amount as any other nation. I played as Creek before and had the entirely of north America colonised and didn't even have half this amount. Is it related to the amount of coastal provinces my colonial nations have? Can anyone link the exact formula of how it is calculated?

Your colonial nations give a fair amount of their force limits to their overlord and any trade company provinces give .5 naval limits per. Otherwise they're calculated primarily by the base tax of coastal provinces.

When they write multiplier here do they actually mean multiplier?

If so I have 18 merchants so my force limit is multiplied by 90. I guess they mean +90 not x90.
