The 2K (Keelboat) Team Racing association, after a couple of years of successful growth of the sport, were ready to move away from a (great, but limited) community-sourced site to something with a bit more design thinking behind it. It was important that whatever we produced be easy to manage for association stakeholders.
2K Team Racing came to me with a really solid logo design, and I wanted to put together a background graphic that was interesting, built on the strengths of the logo, and tied in with the site's content. The four zig-zag lines could be seen as waves, or the courses of four boats tacking up-wind.
We experimented with quite a number of more complex options but it always came back to the simplicity of these four stripes.
