once set (either with or without an additional line to adjust the angle of the vessel), crew goes below and waits, checking for chafing from time to time. No activity of crew is needed beyond that. What I'm curious about is if that is also true of the Jordon Series Drogue. The drogues I have been exposed to slow the boat but still require a crewman at the helm. For a fatigued crew or for singlehanders, this would play a critical roll in what decision to make.
