Night sailing or a canvas sailboat oil painting. Obviously this is not real night time sailing. We hung this large oil painting of a sailboat on the wall and lit it up with a cool rope and globe chandelier. But it got me thinking about night sailing and how boats navigate in the evening. More importantly, how does one sail a boat on the high seas at night. The eyes are very complex and apparently there are three phases of how they adapt to darkness. The pupil dilates to allow as much light in as possible. This could take a few seconds or in some people a full minute. Second, there are chemical changes in the eye that can take up to ten minutes for the cone cells to adapt to the absence of light. Lastly, there are rod cells which contain rhodopsin which is activated to assist with black and white vision. It could take several hours for the eyes to fully adapt. But overall, it takes about ten minutes to get most of our night vision working and a few hours to achieve maximum night vision.

If you’re still interested in sailing at night the following safety tips have been prepared by the American Safety Association. Dress accordingly as the temperature generally drops at night. Carry a decent searchlight for obvious reasons. Stand watch as night sailing means the boat is moving and accidents can happen. Don’t push for speed but operate at a reasonably safe speed. Make sure waypoints are clear and safe. Know the light patterns which are specific to night sailing. And most important, wear a life preserver, preferably with a battery powered light. A lot to know and remember. I think I might just sit back and pretend I’m sailing at night as I look up at this beautiful admire painting.
