Abby, below, is getting diving gear (a mask?) out of a locker and handing it up on deck. She explains to Richard that they're going to do a quick back-down because they think they have something on the keel. Abby: "Kyle's ready to jump over the side." On deck they furl, then turn into the wind. Kyle in shorts and a swim mask, puts a GoPro camera on his head. Maciel stands by with a coil of line tied to Kyle's arm. We see his view as he dives in and checks the appendages, then see a view of it again from the deck. He surfaces. Kyle: "Clear! I'll check aft!" He swims to the stern, then we see him being helped from the water. (When did he pass the GoPro back?) Kyle explains that there was nothing on the keel when he got down there, but that they were already going backwards so whatever it was may have fallen off on its own.
