Some more information about that ongoing collection of information about hull performance and hull shape, from the "Middle of the sea race".
On this race participated several class 40 racing boats, that are performance upgraded Pogo 12,50: Same hull, but more righting moment (bulb at 3m), more sail, lighter and with water ballast.
There was not on this race any 40ft racer to compare (like the Ker 40) but I have noticed that, except on mostly downwind races like a transat, a ker 40 (or a similar less beamy modern racing boat) would be faster.
On the races that have a lo of upwind sailing with bad weather even fast-cruiser racers, like the First 40, can be faster than the class40 racers. Not on this one, but they have not stayed far:
The fastest class 40 was an Aquilaria that had made the race in 4 days 2 hours and 58m, the second was a Pogo 2 that had take more 5 minutes. The best 40ft cruiser racer was a J 122 that had taken more 3h and 35m. The second J 122 made it in 4 days 5h and 50m.
An Azuree 40, a fast 40ft cruiser designed having as model the 40class boats have done the race in 4D 21h and 20m, more 17 hours than the first J122. An older First 40.7, that is slower than the First 40 (there was none racing), made it in 4D 12h and 12m.
The Fastest was the 30m Maxi Esimit Europa 2 (the ex Alfa Romeu with an ugly painting

) with 2 Days 13 h and 25m.
