I have been boating lately with a new boater and explaining the red/green buoys and he keeps asking... why are they so small in height. I really didnt have an answer other than to say they could be that way in case they are hit by a boat accidently to only cause minimal damage or maybe to aid in not toppling over in some winds and waves (given they are connected to heavy chains etc.). I have no problem seeing them because I generally know where they are and also follow on the gps. However, I do sometimes wonder why they are not two or three times higher than they are, for those not as familar with the waterways and to help others "see" them more easily. maybe it is because it would become an eyesore on our beautiful waters. Any ideas? Should I invent a bigger buoy with the addition of maybe a couple more blinking lights (maybe a few just below the top light)?
