Very interesting discussion. I am leaning toward putting a bicolor light above the jib halyard block on the front of the mast, and a combination steaming/stern light set on top of the mast. The steaming light for motoring would face forward and the stern light, of course, aft. Both lights would be turned on for anchoring. The rules say the steaming light must be one meter above the red/green sidelights. It seems to me this bicolor installation would be possible on a fractional rigged boat, but obviously not on a mastheaded rigged boat. I quote from the "Annapolis Book" Boats smaller than 66 feet may carry sidelights on either side of the bow, in the shrouds, or in a single lantern at or near the top of the mast. I am using the single lantern near the top of the mast definition. However, I an not a Coast Guard officer. Perko has a dual lamp steaming/stern light but I do not know if this is legal to use as an anchor light. Model 1196. Boat US say it may be used as steaming or all-around light, so I assume this means anchor use too. Is that legal? Are there any other dual lamp fixtures out there? Maybe something that was actually designed to mount on top of a mast rather than a cabin? My reasoning for doing this is you have to have a light on top of the mast for anchoring, and I would rather have the wiring run only to the mast than to the bow and stern as well. I figure a bicolor lamp above the jib could be seen better than at the pulpit. Plus, there are lots of things that can tangle with or smash a light on the pulpit. I am also thinking of using a combination masthead/deck light and converting the masthead light to a bicolor side light. Aqua Signal has a Series 25 combination light (model 25404-7). I assume the red/green globe of the bicolor light would interchange with the white globe of this combination light. I figure the deck light would illuminate the jib nicely, if I am about to be run down. Anybody visiting a marine store that can verify this theory? (Do you need another excuse to go?) Can anyone point out potential problems for me? John Edwards mentioned the red over green all-around light on top of the mast. Annapolis says the red should be one meter above the green. Lights at the bow, stern and red over green on top of the mast would give the maximum visibility, but I am at a loss as to how to mount that top red lamp. Any ideas? Steve R. M-15 #119 Lexington, KY
