Hey Chuck, Measuring draft can be tricky as the ground may slope to one side so a trick you can use is to place a long level under the keel and extend that out to the waterline, measure down to that. You can extend the level with a straight board or a ladder, and lay the level on it, to get the reference out to the waterline beam. A laser level or string level could also serve. Measure down from the scum line. I expect you have a fin keel, not a wing. They did offer a high performance fin keel of 8' 2" draft. The deeper draft keel allows the builder to reduce the weight, so the boat moves easier in lighter air. Chuck Scheaffer, Resolute 1989 C&C 34R, Annapolis
