They both have stopped transmitting, but Go Quest is still on-line on vesselfinder with a last update at 22:43 UTC. They seem to be at about 70% of the way there.

I don't understand what you mean by "funk= line offside".

funk = to transmit via radio
line offside = to many miles at the coast
(sorry my english is not perfekt)

I guess that akku simply means that they are too far away from the receiver. I think he is probably right, and that also explains why Go Quest went out last, as it probably has a taller antenna mast.

I wonder if the Rocket feet have magnets in them so they stick to the ASDS steel deck when it lands.

Yeah, four huge, powerful magnets on a rocket.  What could possibly go wrong?

It might be fun to watch the crane trying to pull it off the deck when it's back in port, though.  Ever pull a powerful magnet off something and have it suddenly come flying up once you've applied just enough force because as it leaves the metal surface suddenly the magnetic attraction force falls off very quickly?

Go Quest still updating: http://www.vesselfinder.com/?mmsi=367564890

Anybody know or would care to guess how far Go Quest and ElsBeth will stand off from ASDS during the landing? Would imagine they will be ready to move very quickly, either way.

Will ASDS be manned?

Does Go Quest carry Zodiacs or other such boats?

Only if you volunteer. Be sure to wear your Nomex suit and hide in one of the containers during landing.  ;)

For sure. Just have a rabbit hole that goes below deck level.

I expect SpX will either nail this (if a gentle sea state) or will be a long way off target due to failure of some guidance system on the F9 or stability / position holding system on the ASDS. So being in the container with the water cannon on the roof and pumping a protective spray at full pressure should be doable.

Will only be a single M1D, running at min thrust, but sure still a beast.

Apparently current data from vesselfinder, showing Go Quest and Elsbeth III approximately 2 km apart.

And are we sure about 160' figure? Marmac 300 has 18' height how long is falcon 9 first stage + I/E when on its legs? I think it should be ~47m any good source?
SpaceFlight 101 has 42m for the first stage.  When standing on its legs, it should be about 2m taller.  Plus you have to count the height of the interstage.  Judging by proportions, it appears to be 4-5 meters in length.  That's 49 meters, which is about 160 feet.

Add to that the height of the landing deck above the water, and it's mighty close.  They may need to do it at low tide, or at least avoid high tide.

If anybody has better numbers, feel free to correct my guesstimate.

Using HPU height as basis in meekgee's image  I think ASDS deck was about 11.6ft high. and using Helodriver's awesome pics at Vandenberg and JimNtexas pics(July 6 2014) I think 158 ft(minus cap) is its height on legs. So plenty of margin to clear bridge and power cables.
