Spinnaker Trimming: Everything You Need to Know | Live Q+A

How do you get the best performance from your spinnaker? In this week's Catamaran Sailing Q+A, we take a deep dive into spinnaker setup, luff tension, sheeting angle, sailing angles and trimming technique to help you keep the kite flying efficiently and get maximum performance downwind. We also look at why you should never dump the mainsheet when sailing with a spinnaker in strong or gusty conditions, how to avoid breaking your mast, sailing downwind in 25+ knots and heavy seas, jib telltale problems, and how to rig a self-tacking jib without a spinnaker pole.
