Rob steers as MAPFRE reaches with FR0, J2, and J3 but no main. Ñeti, below, talks about the conditions. Blair, below, talks aobut how they've had the main down below since leaving the Horn. Repair is curing and doing a little more hand-stitching. Time to put it up and hopefully it holds together. But it's quite a big repair, so we'll wait and see. Shot of main below. Crew wrestles the sail up. Neti: has been 36 hours since we did the track. Which is good. Shots of Rob at the back of the boom. Hoisting the main. Spreader cam view. Main hoisted. Main flying. Sophie to Neti: Shake my hand. (They shake.) Sophie: Congratulations. Neti: Looks quite good. The track is also good. Looks like the glue is working perfectly. Now we have to be conservative at the beginning. Hopefully we can keep the mainsail in one piece. Don't have much glue. But hopefully it works.Xabi, below, talks about how they were preparing for a gybe, putting in a second reef so it would be safer, and the mast track came unglued, like it did for AkzoNobel in Leg 3. Pretty disappointed, but reacted well. Got the main on the lock on the second reef and ratcheted the track. Now are sailing with the FR0 and double-reefed main. Plan is to keep sailing hard, because these are good conditions to stay with the fleet. After the Horn can maybe do something with glue to repair. Trying very hard to stay in the race. He then repeats the explanation in Spanish.Crash cam footage from stern camera. AkzoNobel is preparing for a gybe in high winds from starboard to port. They gybe happens, but goes too quickly (?), the main slams over, and there's a loud bang that sounds very ungood. We switch to handheld camera on the stern as crew is shifting the stack to port. They send someone aloft, where we can see the main has some major luff-car issues (?). Shot of the helmsman (Nicho?) on the port wheel with a nasty-looking squall beyond him. Awesome shot of him surfing the boat as a wave breaks on their port quarter; shot pans forward to show the crew working around the mast. We see them lowering the main, which has been detached from the mast with lines on the cars to help control its descent. Below, Nicho explains what happened. Had to gybe in 35-40 knots. "Had a bad one. Thought we had a good wave to go down, and as we went down the boat slowed up, stopped; I should have pulled out. We probably would have broached..." But what did happen is they slammed the main into the runner, breaking the battens and pulling the track off the mast. Getting the main down was tricky, with a 50-knot squall happening at the same time. Now just have a jib up, doing 16 knots in 45 knots of wind. Plan is to get the track screwed/glued back on, repair the battens, over the next day or two. But it's going to take time to get to 100%. And they have to be careful.
