Your speed sounds correct. Remember the waterline grows longer as the boat heels so you have to plug that into your formula.

Subject: Stus-List Hull speed
I had my "new" C&C 34+ out for a first sail this week on a blustery day. I am not sure what it was blowing (my wind instrument is awaiting delivery of a pod) but I would guess in the 15 knot area. We had up main and 100% genoa and were doing 7.5 knots steady peaking near 8 knots on a close reach. This is alot faster than my 34 would do under these conditions (note smile on face of skipper), so I put the hull through a hull speed calculator based on the 29.75 foot LWL listed in the specs. It was calculated at 7 knots. The GPS and speedo agreed that I was going faster than this, so now I am curious as to what hull speed actually would be expected. Thanks- Dave
