«“He unravels the mystery of boat tuning and will help you to improve your boatspeed.” (Yachts & Yachting) “This is an excellent book. Some authors might have great sailing knowledge but cannot put it across. Not Pinnell, he can communicate too… He deploys all his knowledge in an organised manner, putting all his points across clearly and succinctly.” (Yachting Life) “With hundreds of photos and diagrams to illustrate every point, the book clearly explains what each control does and how to set it up optimally for different conditions.” (Sailing Magazine)»
