We need some advice on how to set up our radar reflector. We notice many sailors hang their reflectors directly in front of their mainsail mast connected to the bow by two lines underneath the reflector, each going to stantions on either side of the bow. We can't figure out how this set up doesn't interfere with the vairous lines (sheets) connected to the jib. We have a self-tacking jib and this set us would get our lines tangled. Any suggestions?
What you are seeing in other boat's fore triangle is most likely an "anchor ball" (made out of flat pieces of black metal or plastic). This is something you are required under the colregs to display when you are at anchor. It is very unlikely that anyone would put their reflector here.
your radar reflector should be permanently attached, as you always want other vessels to see yours. A favored spot is attached to the forward edge of your mast (main and/or mizzen). If on the main mast, your head sail will brush against it when you tack, so you may wish to choose one in a container like a Blipper (looks like a fender). Otherwise you can affix it below your spreader, perhaps wiring it to one of your shrouds.
