Aloha,
I cannot speak for World of Tanks but there is NO SKILL BASED MM for World of Warships and more than likely there never will be. Because there are so many mechanics that people may judge as "having skill" that it would be impossible to work out and make functional in random battles.
It's probably a better idea to make judgement and inference off data that exists or actual posted policy.

Ships does not have any skill based matchmaking mechanics.
Matchmaking is based on the following factors for ships:
+/- 2 tier spread
3 minute based hard caps for ship types
How often a player has been uptier'd in the last 20 games
5 minute cap for full games
Newbie safe cap (first 70 games)
Hard caps on ship types per games (Tier X CVs for example)
Fem,
No.
