On to my next anal subject. Replacing my side of cabin name boards that hold my nav lights and noticed something. My old Perko lights are in a 90 degree casing. They are supposed to be seen from dead ahead to 22.5 degrees abaft beam. OK, how does that work? The PO of my boat had the name boards set up so they angled a bit towards the stern. Meaning the spacer at the forward end of the board was thicker than the one towards the stern. But....if that is done doesn't it mean that there would be a blank space in-between the lights from dead ahead? How do set up 90 degree lights so they are seen appropriately? I do notice that the lens is not 90 degrees but is curved a bit at each end where it falls into the casing. Does that take care of the issue? Just set them up for and aft with the center line of the boat and the lens does the work?
