Michael Typically sport boats have their planning capabilities accounted for in their PHRF numbers. This is one reason why limiting a course to strictly W/L is not always desirable as it takes away a major component of some boats speed by removing any reaching legs… that is a discussion for another time though.
A Viking 22 is not a sport boat but is light and will probably surf quite well in a wind. By contrast they would be pounded mercilessly going to wind in those same conditions. Our first ever race on our former J27 was a 52 mile port to port distance race with winds well over 20 knots TWS coming over port quarter (likely much more). We were regularly exceeding 12 knots over the water on the ST60 Speed instrument as we surfed down waves. We would then drop off to 7 knots as we stopped surfing each time. We hit a high of 13.9 knots that day. (which we never ever saw again while racing in 7 years). During the same race the boat ahead of us was a Peterson 37. They never came close to 13 knots but they also never dropped below 9. The boat immediately behind was a C&C 34 – same thing as the Peterson. I suspect your 30 would also not slow down as much after the surf finishes as the lighter 22 but would have a pretty nice average boat speed during the day. I should note that after we dropped the spin and went with just a main for a while we continued to exceed 12 and drop down to 7s. We averaged 8 knots over our course that race. It was a wild and wet day. At the bar after the finish a friend in a Tanzer 22 was there less than an hour after we finished and he flew only white sails. Usually he is several hours behind. The only other time we hit high speeds on speedo was just after we abandoned a race due to excessive waves and wind and were reaching back to port under reefed main and 100% headsail. While I was attending to cooler duties we surfed down a wave and briefly hit 15.0 knots. Despite that it took our usual time to get back. As a proud papa of the boat I selected Max Speed both times and took photos at the dock. On the day we hit 15 after abandoning a C&C30-1 won the race.

Not including surfing or being pushed by waves I rarely get over calculated hull speed on my 30-1. Sometimes do it reaching on flat water with the 195% spinnaker. In one case I did get to about 7 kts, which leaves an impressive ditch directly behind the boat. At the same time a Viking 22 slowly passed me. Afterwards the skipper claimed he was doing about 7.2, occasionally 7.4. I have wondered from a PHRF handicapping perspective if a number needs to be factored in that covers the "ease" at which a boat can exceed hull speed. The sustained highest speeds I get to are with a deeply cut 90% jib around 22 kts true. It sheets in front of the spreaders and inside the shrouds. As long as I am not pounding into waves I can do 6.5.

I have never seen that on my (sometimes well sailed) 30! Gary
