I think the difference is I didn't use THEIR rigging - I had a 12ft aluminum mast, so I got a Laser Radial sail and cut a foot off the foot. Iirc I also moved the centerboard forward from where they had it. On my first sail in 10 knots +, a powerboat came over and asked if I had an engine in it!Thanks for the thoughts Druid. Interesting you sail the D4/5 sails well, I have heard it is kind of lackluster when it comes to sailing.
As for davits, I never used them. I just the use jib or spinnaker halyard to haul the boat up onto the foredeck.
