Much as with any other conventionally rigged yacht, the balance between the main and fore sails needs to be correct. When fully sheeted in, the main should not be on the centreline, but a few degrees off. The fore sail should be a little further out. This will ensure that the steering induced by the sails are balanced, allowing the rudder to do its work.
There will come a time as wind speed builds up when you just have too much sail, and everything else is overpowered. When this happens, I take the chicken way out, let the sails out, and gybe round with fingers crossed, then do my best to get the boat back to where I am, or to where retreival is easy.
Rigging the sails for correct shape to give optimum performance requires a sizeable book, and plenty of practice.
Happy sailing!
