211. If help has not arrived in 10-12 hours after you abandon a remotely-located MODU in a survival craft, which of the following would be the best course of action?

After 10-12 hours without rescue following MODU abandonment, the best course of action is to shut down the engines and deploy the sea anchor. This maximizes the probability of detection by search and rescue units, conserves fuel, and stabilizes the craft, all while remaining near the last known position which is the basis for search planning.
