Sails for offshore cruising are usually at least partially radially cut to better withstand abuse. In radial designs the seams carry very little load and are less prone to ripping even if let flogging. That said, never allow your sails flog in the wind for an extended period of time – every sail ends up ripping when let flogging. It’s also worth noticing that nothing ages the sail faster than flogging.
