Re: Lighting ...
In addition to using the required nav lights, flying a good radar reflector is a good idea. The larger vessels will be able to pick you up on their radar easier but may not be able to change their course. Keep in mind, according to the regs, these larger commercial powered vessels have the ROW over the sailboat under sail. For safety, it's always smart to maintain the required lookout and alter your sailing course as required to avoid colision. Keep in mind that gradual course corrections are not as easy to view on radar as a hard course change. A good rule for sailing safely is to hold your course if you are the stand on vessel but be ready to give way at any time because the other vessel may not be paying attention or not know or care about the nav rules.
Be aware and enjoy the evening sails.
