I recently purchased a Royal Manilla Galleon that had a max speed of 8.9 knots, despite no speed increasing upgrades in advance. I figured that this was an excellent attribute for such a ship, bought it and wanted to uppgrade it. But when I did so, (adding the higher masts and cotton sails) she somehow actually became slower! I reloaded the game, tried it again .... same thing. I understand that there has an element of volatility been introduced to how effective which upgrade ends up being on any given ship. Which I actually do quite like. But it definetely shouldn't become slower ....... or should it? Could it be that the stats of the Manilla Galleon (and possibly some other ships) produce implaussible results when getting speed related upgrades? Or am I missing something? Edit: Alright, the problem now also occured with a Light Fluyt of War. All of this hapened in the "shipwright's office" on the French settlement of St. Martin.
