Thanks a lot for your fast response and answers Jeffrey.
I was investigating the slow ship issue, and discovered the buccaneers reef Forum, found the solution. It seems that MK worked in the Dinamic navigation not the Tactical ones, and I selected Tactical navigation, so it was a problem of the stock game, If you use dinamic it's all well.
Also, I was reading the forum a little, and realised that the developers, maybe you included, were burned out of different situations etc.
I want to thank you and MK for all of your awesome work, sincerely I have no words describing how you are able to make me feel playing this fantastic game. Please, send my kind regards and thanks to MK aswell.
