I liked this description of the sea in front of the boat looking like a crowd viewed from behind with their hair ‘arranged’ by the wind. You can imagine scurf and foam looking like grey-haired bobbing heads.
‘Some of the swells were just breaking under their own weight. Behind me, the little grinning teeth of the breaking seas were scattered across the whole visible width of the Minch. Downwind I couldn’t see them. If I looked ahead of me, it was like a crowd from behind, a sea of wind-coiffed heads.’
