Anti whaling activists using UAV to track whaling fleet

Just found this in the news:

The Sea Shepherd ship, Steve Irwin, deployed a drone to successfully locate and photograph the Japanese factory ship Nisshin Maru on December 24th.

Would be interesting to get more information about the system they use... (Range endurance etc.)

Especially the recovery on the small helicopter deck could be challenging.

Merry Christmas to all !!

Pretty sure if the platform is not water tight that the net on the deck is involved in the recovery.

Would be keen to know a bit more about the platform, how stable it is in winds, maybe folks could use in sea rescue ...

Brian: the net in the picture is to prevent helicopters that land on it slipping off the helipad.
I would guess they rigged a vertical net of some sort to catch the drone. I'm also curious as to how they launch the plane. No way I would want to try hand launching this thing. The picture looks arranged as part of a publicity stunt.

Looks like the same type that have been suspended to catch small uavs on navy ships in the past, but eitherway a net of some sort must be in the process.

Judging by the launcher's hair it seems they are in fact launching with the wind so a hand launch could be possible, especially if the ship slows down.

With the way nautical winds occur it is very likely that they are hand launching into the wind no problem, they could even land without the net with the ship moving into the wind, groundspeed matching ship's speed isn't too difficult with a good wind and it can hover right down (seemingly)

Its an AttoPilot platform last year they successfully turned around the whaling fleet just by saying they were going to launch. (Whoops just realised they are only talking about this years experience....)

Chris Mc Nair is a member he will tell you all about it. The crew untook training with him and Dean.

There are other things but they are under embargo. 

Perhaps you could ask Chris about the 24 hour platform.

I believe I am right in saying that the drop it off the side method is sometimes employed. Again Chris is the man,

Don't forget they are having an offer on airframes and APs at the minute $9999 for a complete system. 

Proven throughout the world!

Even the wet bits.

Heres how a high surface wind speed landing might look. Even managed a couple myself

Exactly Gary, that landing just on a boat, very easy.     I'm not sure how many of you have ever been out on a large vessel, a cruise ship perhaps, but you can often see seagulls just floating midair flying into the wind, maintaining relative position to ground things but still "flying", doable and not overly difficult with AP assistance (manual would be a bitch though)
