Re: What do you use for headlights
Boating at night without auxiliary light can be a safe enjoyable experience if you have normal vision and practice. Each night that you are still above ground is a good night to practice night navigation.
"Slow" speed, that is under ten knots, is a must. At that speed you are covering over 16 feet every second. It is almost impossible to adequately examine the water for obstructions faster than that.
I am an inland boater so there are stump fields, sawyers, rock outcrops, shoals floating debris, drunk boating operators (sometimes in their boats

) even an occasional animal to run into. None except the occasional rock outcrop are on any chart. GPS is useless for these, yet they can sink you just the same. Slow speed will allow you to spot them in enough time to take the appropriate action.
Learn to point your eyes 10 to 12 degrees away from the spot that you want to see at night. The blind spot in your eyes will prevent you from seeing anything you look directly at at night. Keep your eyes moving and pay attention to things caught in your peripheral vision. To practice this just turn out the lights in your house and walk around trying to find a book or other article.
Smoking and alcohol consumption is very detrimental to night vision. Avoid them if you are going to navigate at night. Douse all lights including instrument lights except the oil pressure and temperature lights and radar. They should have the minimum amount of red glow to read them by. This is where analog dial pointers are far superior. Your visual attention should only be occupied by what is in front of you. Let your ears tell you about the engine speed and other conditions.
You can learn to tell where there are obstructions under the water by watching the wave patterns on the surface. Note their action during the daylight as you are learning.
As we get older it is harder to see at night, but training yourself will work well and you won't need a light in good weather.
Learn the feel of your boat on the water. As you approach shallow water the engine will slow as the hull friction goes up, the helm will get more sluggish and your bow will drift slightly towards deeper water. The old time tow boat operators claimed this phenomenon was caused by a boat trying to save itself from a poor pilot.
And yes, I do use a sextant, a lead line and a chip log in addition to my electronics!
