Gear: 3Di - the shape of speed?

New 3Di Headsail to complement the 3Di main. We've actually been hanging pretty well upwind so it'll be interesting to see what this does for us. Certainly going to be nice to have a fast sail without a leech hook.

Overall the sail looks a bit deeper (inches) than my current #1, both at the foot and the upper leech. The airfoil looks smooth and in theory we'll need less halyard tension to keep the draft forwards.

Sadly its going to be a couple of weeks before we get wind, or so it seems right now :( Can't wait to try it out.
