My thoughts are:- the style of trapezing technique has to match your ability / mobility around the boat. The ultimate technique is to reduce the number of movments required to the minium, but that is of no use if there are other issues that have to be dialed in.
Few examples:-
If the boat is already at the perfect sailing angle , as you go out on the wire unless you sheet in the added leverage will drop the boat back into the water, the solution is to sheet in as you go out, if that were possible.
When tacking if coming in off the wire you end up sitting down you will then have to get back up on your kness to cross the boat adding a extra movement. Coming in on your knees removes that extra movement.
These are great words and coaching suggestions, but to be honest you need to do what you are happy with first enjoy it and then build from there.
If there is enough interest and the club would allow it may be wecould arrange a a coaching session pre the sport nationals at Instow, half a day or something? any takers?
