I was fortunate enough to have a look around HMS Liverpool, a big navy ship with a helicopter deck at the back. I remember there was a grid of holes in the central area of the helicopter deck so I asked one of the crew what the holes were for. I was told that the helicopters were fitted with a downward-pointing spike thingy which would grab the holes as the helicopter landed so that the helicopter was held down and couldn't get bounced off if the sea was rough.

Would SpaceX's Falcon benefit from using such a system to anchor it onto the floating landing pad?
