This really happened:You are returning, under power, from a cruise/race with 15 miles to go to the next port. You knew you had limited fuel, yet plenty to get to the next port. A mayday comes across the VHF from a crew in a life raft 10 miles offshore. Conditions are calm with no rough weather in sight. The Coast Guard, recognizing you could get to the scene before them, requests that you divert course to pick the life raft crew up, but you do not have enough fuel to divert to get the life raft and make it to port. What do you do?
