The Sailwave logo went through a few iterations. The first was a similar sail/wave icon but the sail was convex. Currently I cannot find any examples of it. The font used for the text was Joker. I showed it to my friend Mark Pressdee who suggested it needed to be “more serious” and I switched to Napa SF. I can remember being a bit disappointed at Mark’s reaction at the time because I thought Joker was cool, but part of knew knew he was right and thank goodness for that because Joker is another Comic Sans these days 🙂 Later I redrew the sail in a concave way; a scan of which is below. This has been used in all Sailwave logos since. It’s never been professionally drawn.
