Classic Lightning Common Measures and Fitting Placement Information
To Assist owners of older Lightning's restore and refit their boats. The purpose of this form is NOT to capture compliance with Lightning Class Specifications, or to mandate how one rigs their own boat. The purpose is to create a simple tool to compare boats and inform boat owners of how others have rigged their boats. One should be able to complete this process in about an hour.
