I thought anchor light is white and 360

Recently in Italy i saw a beautiful classic megayacht. At anchor it showed two red each mast. Next to them was a big sailingyacht showing one red and only last night on Malta a motorboat shoring one green either side at anchor.

I think that there is something that if masts are over 100 foot height, a red light must be shown at the top of the mast to warn low flying aircraft.

There was an oldish looking wooden yacht on Weymouth Quay the other day with a strobe light on top. Must be very distracting to others unless they can switch it over
