Portsmouth uses wind speed ratings or DPN. DPN is 80% of the B4 rating... eg 12 to 18.

SCHRS and Texel use righting moment in the formula so it is considered. Texel did calculate two ratings... hull flying and displacement however most of the Dutch clubs did not use the two ratings because the variance of the sailors was greater then the rating difference at the club level... (basically it wasn't worth it)
