Is there an electronic strategy with alarms to avoid collision with
floating objects while sailing ?

A full description would be appreciated.

Thank you.

I'm afraid the human eye ball is about the only thing that can keep you from
running into floating debris..

The stuff is so low in the water that it can't be picked up by radar. A
debris object would have to be nearly as large as your boat to set off any
radar collision alarm..

Keep a good watch and have a stout boat.. Failing that, have a collision mat
in the emergency locker (along with a plan on how to use it).

This hasn't been my experience. In calm inner waters, such as the inland
passage along the west coast of Canada, radar when set to short range can
commonly pick up a log or the top of a deadhead if it breaks the water's
surface, and it will routinely pick up a seagull standing on top of it. In
fact, I've even seen it pick up the riffles from a tidal rip.

Interesting.
Model? Antenna height?

Thanks

Maybe on a dead calm sea.

The waters cited are not prone to large swells, but I have been in a water
taxi late at night and seen the radar pick out logs and other debris on the
water. It was overcast, poor visibility and moderately high wind at the
time.

Unfortunately, did not note manufacturer of unit.

If.....radar was THAT sensitive then why was I, sailing a 43 footer, nearly
run over by a tanker in the English Channel between Flushing and Lowestoft?
The weather was stormy, rainy and it happened in the middle of the night
during a downpour!
And....vessels are not on auto pilot in that location.
Radar is a tool, but it does not replace common sense ;-)
