Now I might be imagining this, though freestylers have told me they notice sliding tricks go on forever in shallow water, but how much easier is it to gybe in the shallows? Is the ground effect significant? We occasionally get a gust over flat deep water in the lee of a local reef. Thinking about it I reckon you have to watch your trim a bit more carefully to come out with a respectable amount of speed in that deeper water. But there are a lot of variables. What do you think? Is it more than just the flatness of the water?
