Your panels would not survive a good rinsing either, that has to be a consideration for this type of event.

Absolutely correct. Panels were put out in that configuration under tame conditions. It's pretty trivial to take them down and stow them quickly if necessary.

Yep but for ocean passages in the high mid latitudes they would have to be permanently mounted and finding a functional place for solar is an issue on boats of this size. But for cruising in not so tricky stuff your solution is good. I have used similar. Panels can be stowed under a mattress when not in use.

Simon has been stuck in a lull for the last couple days. Kirsten and Abhilash are closing the gap. The next several days could get very interesting.

He must be tempted to fire up the donk. I am hoping to to row out to wish them well during their stopover... daylight, weather, and work permitting!

Yes it will be interesting ... it looks to me like Kirsten will have more upwind work to the gate than Simon though

Looks like Kirsten could close to within 90 NM by Tasmania.. with 35 hours in the bag that potential puts her in the lead in time if not on the water.

She is now directly astern of Simon but either way yes she looks very likely to be less than 35 hours behind at the gate

Digging through Google Maps / Earth I came across this view. If it were realtime you would see Simon out front very soon. Damn...I need to get myself to Tasmania sometime soon.

Lion Rock is a favourite surf spot of mine.... Looks like Simon will moor any time now, if he's there when I finish work (a couple of hours) I may pop down for a look.

I reckon i missed him by about 15 minutes.

So talk me through this running sail. The high cut clew furling jib/genoa I understand. What is this running sail, not kite material or sizing and not a jibtop either ?

Buggar ! Earlier Simon slowed to 0.8knts and has now turned back towards Hobart at similar speed. Not much of a Christmas Day for him
Good evening,
It is a two ply sail.
Both the luffs are stitched to a single boltrope which fits into the roller furler foil.
The two clews are separate.
When heading upwind or reaching, the two plys lie together and the sail looks and sets like any headsail.
When you run you seperate the two plys and pole out the windward ply. The leeward ply fills on its own same as if it was the leeward or leach area of a spinnaker. Or you can set the leeward ply on a second pole if you want to. I don't think Kirsten does that though.
You can reduce the sail area while running by just furling the two plys together on the furler. The headsails areas stay balanced.
When you go onto a reach again, you just let the weather side sail flop over onto the leeward one.
Some maneuvering with sheets are required.
North Sails in Cape Town suggested the sail for her.
Regards.

Roll inducing machine. Better used well off dead down wind to avoid the death roll.

Agreed. This all day for comfortable and easy vmg on displacement hulls. Self steering loves it too.Roll inducing machine. Better used well off dead down wind to avoid the death roll.

Looks like Simon was catching some sleep and the light wind changed direction on him.

or using a Solent rig, the second article):

Two Headsails Are Better Than One
Being able to fly twin genoas when you're sailing off the wind far outweighs the aggravation, when sailing closehauled, of having to furl to tack. From "Hands-On Sailor" from our August 2010 issue

MODERN TWIN-HEADSAIL RIGS: Simbo Sailing and the Dutchmar Zoom Boom - Wave Train
The concept of the twin-headsail rig, where two jibs are set flying side by side, was first propagated back in the 1950s by bluewater sailors who wanted an easy-to-manage rig for sailing deep downwind angles on tradewind passages. The idea has been revived of late, first by an acquaintance of...

The vid on the GGR site with Don McIntyre sending Kristen off has some description of how it works, as she’s on board setting sail, and he’s on the pursuit boat describing how’s she setting things up as she’s working on deck. Some description too, I think, on the vid of her arrival in Hobart. BTW, Mark Slats effectively used twin headsails in the last/first GGR.
