I too noticed such an improvement in sailing qualities with my Gori folder in terms of acceleration in a puff that I had to revise at what apparent wind speeds I would change my sails (I have hank ons).

Basically, I got the better part of a knot for "free" and while I haven't noticed much change in "top speeds" for a given sail area, set and similar apparent wind speed, I get there quicker and the whole motion of the boat is "sprightlier" if that makes sense.

I can't necessarily attribute this to the folder, but my hull speed is, in theory, 6.9 knots on a 26 foot LWL. My GPS in current-free water once recorded 7.3kn on a close reach on a day with 25 knots, a No. 3 and a single reef set. Last Sept. 28th, with 25-28 knots, a No. 3 and a full main set, we hit 8.9 knots SOG on a beam to broad reach. I've never surfed for so long in this boat, and while I can't credit having a folding prop, my gut says that taking that resistance out of the equation allowed us to get surfing sooner.
