Learning to shoot a new boat

While the Emirates Team New Zealand sailors have been learning the ropes for sailing the AC72 class catamaran, I have been learning the techniques and angles for shooting the boat.
Keeping up is a big part of the challenge. With the yacht doing close to 40 knots at times shooting from the chase boat racing alongside takes quite an effort to keep the boat in frame and to hold on.
I'm still trying to find all the good angles but at the moment it is sometimes more prudent to stay out of the way.
