They've got extra equipment and extra water from Cayenne (courtesy of Michael M), plus Will Paxton.
Tiburon busted their rudder.
They'll be fine. The real question is whether they're faster with alternative steering than California Condor was a few years back
Here is Jim Antrim's account of that 2010 Pac Cup: http://www.pressure-...010-Pacific-Cup
Four days into the race, past the half way point, they went from doing 20 knots(!) in 22 knots of breeze (average speed: steady 14+) and expecting a first to finish... to breaking _BOTH_ rudders and taking another 8+ days to finish using a Jordan series drogue to steer.
We set to work over the next few days, experimenting with different sail combinations, trying to increase speed by reducing the length of drogue, and jury rigging one of the rudders. The drogue length we settled on was shorter than ideal, less than ¼ of the full length, which meant that we had to steer constantly and our course was unstable. “Steering” consisted of playing one leg of the drogue bridle while standing at a winch, ease for a starboard turn, crank like mad for a port turn. The boat swung back and forth drunkenly but our speed was up to around 4 knots and on average we were aimed at Oahu. After a couple days of hard work we had a rudder ready to mount, with gudgeons jury rigged from old cracked and broken pieces and spectra lashing. Would it survive a day or a week? Should we mount it now or save it for the final approach to Hawaii? We decided to go for it. Several frustrating and exhausting attempts to mount the rudder ensued over the next few days. As David said at one point, “It takes three men and a forklift to mount this thing in the boatyard.” Not an easy thing in a seaway to mount a precisely aligned blade and get two pins aligned and inserted. Each time we refined our technique, and waited impatiently for the next lull in the wind and seaway.
