Cool picture! I bet any skippers in the area choked on their coffee when they saw this... :P
I also try to make my boat 'fly' out of the water sometimes, but I find it much harder in SH3 compared to SH2. In SH2 I would first go deep, order ahead flank, blow ballast, and manually set dive planes up. I did some spectular surface-breakers there!
How did you manage this in SH3, and what was your speed when you surfaced?
