Some guy called "Ashby", anyway I never heard of him, must be some amateur or something.

I know, that wan't my point.

Maybe that other sail helps when moored?

Thats to keep it head-to-wind when on the mooring.
I have used it on a yacht, where it attaches to the backstay instead.

Looks like an anchor riding sail (which keeps the boat pointed into the wind) to me. Apparently they carry more sail at anchor than the Hobie has altogether, lol.

It's the "parking sail" - one of two that are on each side of the boat when it's at its mooring. Keeps the boat pointed into the wind.

The huge wing sail doesn't do that already? Seems to me any little puff comes along, especially 150' up, and those little parking sails will be about useless keeping that thing straight!

Now, if the big stick were not there at all, sure, Lobster boats have been using these for years, but how effective are they next to a 200' tall wingsail?

I think they will be alright.
Five guys sleep aboard at night, including a guy that can sail the thing.

Do they have one of these?

A Chinese junk parked behind the boat. Must be building it China like all other builders now.

I think it's for **** shade for the guys left on the boat all day when it's not actually sailing.

Well, no the wing wouldn't. A boat at anchor will naturally yaw back and forth to the wind. If it has any source of lift (above or below the water), then it will tend to sail upwind on its tether. The anchor riding sail(s) is(are) there to impart a big weather helm. They cause the boat to pivot head-to-wind before it sails too far. Two such sails (tacked outboard at the sterns) would turn the boat quite aggressively.

Ahhh, I see. But why don't they just put out a stern anchor since people will be on board anyway?

they're little sails to help the boat and wing weathervane into the wind better.

Tony, this just cracked me up, Laughing my butt off!!! Thanks
The question is, does he have the keys to the engine????

1) Because the wind may shift.
2) A stern anchor won't keep the boat from yawing, it will just stop the boat (with a jerk) when it reaches the end of the line.

What you really want, is something that keeps the boat pointed into the wind, so that it doesn't want to sail away in the first place - which is just what an anchor riding sail does.

I've helped run several regattas using a friend's Beneteau 44 as a signal boat. It's keel generates enough lift that, when at anchor, it will sail off to one side, stall, drift back, catch, and sail off to the other side all day long (which is not what you want happening to one end of the starting line). A small sail hoist up the backstay keeps the boat pointed into the wind and it stays put very nicely.

Yeah but, were you under bare poles or did you also have your 200' high wing sail? Maybe the reason they keep 5 crew on board all night is to "sail" it at anchor, so it doesn't try to go away if it gets sideways in a windshift?

How do you know the guys on board are jerks?

The guys are playing cards all night and playing on the internet - they're on security watch and to have capability to deal with some unforeseen scenario should something happen. They're not actively doing anything during the night...the boat weather vanes directly into the wind nicely.

The "guy who knows how to sail it" and is sleeping on board is "Blunted", the same C Class sailor who posted here about a year ago a bunch of pictures of Cogito, its wing and other C Class challengers, with and without lifting foils.
The "small" twin sails are anchor riding sails indeed.

Are they racing for pink slips?
