Hi,
<br>I had a question regarding the USSA Multhull Modification Factors. In particular, the correction for sailing "light" (either with a light total crew weight, or solo on a two-person boat, which I beleive gets the same adjustment), seems excessive. For 70% or lighter than the class minimum, you get slapped with a .970 reduction. This is more than if an "at weight" crew added a spinnaker! (which is .972). This equates to nearly 2 minutes per hour sailed (or approximately 18 sec/mile in the PHRF time-on-distance world). Even if sailing solo, which would be a significant weight reduction, on a normal course there is much to do on the boat by yourself, so you may have faster boatspeed, but reduced capacity for boat handling. I still don't think you would beat the same boat with normal crew weight and spinnaker. Maybe the spinnaker rating is the flawed one?
<br>Any thoughts in this regard are appreciated.
