LIGHT AIR TIP
Light-Air Sailing by Rupert Holmes (June 2018) was a very informative article. The section on sail shape and trim is especially good. I think one minor but important point was left out. Never just hand-hold a sheet, no matter how light the wind. Always use at least one turn around a cleat or winch drum. The explanation is well grounded in the science of kinetic energy and momentum transfer between the air and sails, and the way air attaches to and flows around the sails. Good job from a SAIL magazine subscriber since 1983.
