Sails Overview

Asymmetrical spinnakers


Spinnaker Coding Explained: Most spinnakers fall into five mold shapes to suit different wind speeds and wind angles. In the 1-5 numbering system, the even numbers designate running shapes and the odd numbers are reaching sails.  Lower numbers designate lighter wind sails and higher numbers are for higher wind speeds.  Code Zeros were invented after the original numbering system and they are very flat spinnakers for light air close reaching; they are a must on boats with non-overlapping genoas.
