Re: Visibility of course marks
I've noticed that a lot of the smaller channel markers/lateral buoys are now made of plastic too....
Inflatable marks are best by far, for racing, but too expensive to leave in place and cumbersome to work with on a regular basis. We used to use 'man overboard pole' style marks with flags, cheap to make from PVC or bamboo, a foam float and some ballast. No big loss if a barge, log boom or freighter drove over it and took it away.
