Sheerness Tidal Curve

I have a very small, straightforward illustration that I need redrawn as a clean, background-free vector. The artwork is flat in style—no gradients, shading, or extra effects—so this should be a quick task for anyone comfortable in Illustrator, Inkscape, or similar vector tools...
