Just to give you an example and comparing an Alberg 30 with an Elan 31 sailing with 8K wind, the Elan is about 2 times faster.

More precisely, considering true wind:

at 40 the Alberg is making 3.1K; the Elan is making 5.2K.

at 60 the Alberg is makig 3.2K; the Elan is making 6.5K.

at 90 the Alberg is makig 3.0K; the Elan is making 6.7k.

at 130 the Alberg is makig 2.7K; the Elan is making 6.5k.

The Elan is a good cruising boat with a great interior and a very good stability. If we compare the Alberg 30 with an offshore cruiser more race oriented like the A31, those differences would be bigger.

I don't know where these polars came from or who was at the wheel or what sail configuration was used but I can tell you my A35 (very similar to the A30 in design) goes a hell of a lot faster than 3 knots with 8 knots of wind on a beam reach. With 160 genny and full main, I am doing closer to 6 knots, still relatively slow when compared to modern hull designs but not THAT slow.

Alberg 35: With a philosophical flourish Cato throws himself upon his sword; I quietly take to the ship.
