Vang on sprit?

I had the same problem on both the Nymph and the Surf that I built.
Pulling harder on the sheet or on the snotter are not the way to go.
The problem is that the fitting on the front of the mast where the snotter
runs through and down to cleat is not high enough. Try moving it up the
mast 6" to a foot. This will angle the sprit upward more and give you the
effect that you want.
The down side is that maybe then you will find that your sprit is a little
too short....
