Night Vision
Dan,The prudent thing is to never plan an overnight voyage without sufficient crew to maintain a 24 hour watch. There's lots of traffic out there, especially near the coast and shipping lanes, but even a single ship or boat seems to be attracted to another like a magnet! Floating oil drums, other debris and even whales are hazards that are very difficult to see at night. Changing weather conditions can put you at risk if everyone's asleep. I would not attempt an overnight sail without a pair of eyes, two pairs are better, on deck at all times. If not enough crew to have two on watch, they should take short watches as you can fall asleep at the helm! Even the best plans may go awry. I once set off on a 24 hour trip to the Dry Tortugas out of Fort Myers with a crew of 6 and a carefully planned 2 hour overlapping watch schedule. After a couple hours in 6-8' seas and 20-25 knot winds, 4 of the crew were so seasick they were out of action. Bear in mind they were all experienced freshwater sailors who had taken occasional saltwater trips but were unacclimated to sea conditions. That left two of us to run the 44' boat . It was a long night!Of course, there have been many solo sailors crossing oceans and they must sleep but usually try to sleep in short shifts so that they can periodically check on things. Some heave to, making sure proper lights and radar reflectors are deployed. You can position a flashlight to shine on the sails which makes you more visible. No one should ever be on deck at night in any condition unless properly clipped on with safety harness, PFD, personal strobe light and monitoring the VHF. Night sailing is not to be taken lightly!Dick VanceH-25.5 "Honey Bear"
