I can be surprised of whatever I feel like, sir. Whats the matter with you today? Take it easy. If I feel I have doubts of sea and carrier operation, then I can ask here, hopefully without any clown telling me what I should or should not know. GB was kindly explaining what I didn't understand, if you don't have anything useful to write, then please stay out of my way. I'm fairly new at the forums but these guys are the ones that get new customers away.
