Why do people listen to me? I don't know if they do, but by my process of osmosis to sledgehammer, I try and get my points across. But if I'm going to suggest something, I back it up with metrics, which might include visual evidence, photos. In 2015, with Quantum Racing, we started the year with mainsails that were quite deep on cambers, quite twisted, with low traveller position, and struggled for speed upwind. We looked at photos of boats like Azurra, which started the season with a flatter mainsail and a little bit straighter leech profile. They sailed just a little bit higher all the time. We studied Azurra's mainsail relative to ours and started looking at the data. Through the week, we made improvements. You've got to start that process. So, I suppose that part of my job is to occasionally tell the emperor he's wearing no clothes.
