VIPER General Settings

  VIPER Tuning Guide

 

The tables below show some general settings currently adopted. These are guidelines that will help you gain control over your boat more quickly. Be encouraged to try new settings, as this will help you learn how all the controls affect the boat. Remember, if in doubt, look around, do what top sailors do and ask why they do this. There is no magic, instead, just experience and understanding the elements and your boat.
