Wouter, you really have some serious issues to deal with!
I have done two complete seasons in NED, I have never once seen you on a race course (although I am told you were at the REM race this year). So I must assume your tactical pointers are taken from events that I haven't been to. They must be the big serious events to warrant such pressure situations.... Let me know some details of these events so I can book them into the team calendar for next year. Hopefully we can represent the F18 class in a better way than you have experienced so far.
I do a lot of F18 racing and have never once had experiences such as you describe, so possibly it could be to do with the way you are interacting with those around you... Much the same as you seem to get on peoples nerves here

Happy sailing.
