Concepts covered:dynamic rig controls, wireless load sensors, sail depth, sail twist, mast compression

In this video, Charlie Cumbley from North Sails and Cyclops Marine explains how dynamic rig and sail controls, such as jib sheet, mainsheet, and backstay, affect sail shape and boat speed. Using wireless load sensors, sailors can monitor live data to optimize their performance by adjusting sail depth, draft, and twist according to varying wind conditions.
