Just read about these ''saildrones'' in AFLOAT magazine and was wandering:
What happens if a cruiser or a vendee globe racer hit a saildrone and sink?
The CSIRO website says that [they]''are equipped with both automatic identification systems (AIS) and ship avoidance systems to alert and avoid other ocean users''. Knowing the number of ships that are still not equipped with ais and that I doubt a constant radar surveillance system is equipped on these things, are they a real danger for small vessels?
I don't find any mention of this on the saildrone website

I recon they would be hard to spot on a good day impossible in foul weather or at night , they might not even show up on a radar displays.
they have ais. what about when the battery or technology fails ect no ais.
there's no one to keep a proper lookout. so i not shore how that complies with regulations

id imagine a Collison with a multihull or fast light weight racing yacht would do some serious damage maybe not to bad with a slower cruising yacht

I'm not sure how many there are but according to the article they will be used mostly in Bass Straight North of the shipping lanes. They will be monitored 24 hours a day using a system similar to what Commonwealth commercial fishing boats have to carry I suspect. It is probably no different to ocean weather buoys as far as hitting one.

C'mon, the things would be lucky to weigh a hundred kilo's, you'd sail through them and not even know. I reckon there's much worse things floating out there to hit...

Yep. Tree trunks etc. Most likely be a glancing blow anyway. They are really interesting!

"Professor Noad estimates more than 30,000 humpbacks alone will migrate northwards up the coast this year, roughly matching peak historical numbers"
Personally I'm happy to take the risk of the Saildrones floating out there considering the benefit they bring.
I don't believe they have as much potential for causing damage to a small vessel than a whale, (and whales selfishly have resisted adopting AIS), as well as the chance due to th enumbers involved.
I can personally attest that running into a whale weighing 10-30 tons is much more scary/risky than I believe hitting a saildrone weighing 100's of kgs would be. I don't think they'd do much damage to be honest, all things considered.

Yep the risk outweighs the benefit to me too. Say you sailed out into the ocean blind folded, with the intention of hitting one, I dont think you ever would.
