In Response To: Re: This and that (John Pinney Dagnabit 6.7 ky lake)

the simple answer to why is that it makes things a lot more fair. The performance lost by not using a spinnaker is different for all boats. A good PHRF committee will try to come up with a fair allowance for non-spin rating (I asume JAM stands for Jib and Main). It should be noted that as a rule, base PHRF ratings are for spinnakers and 150% genoas, as that is how most boats were designed to be sailed when racing. Scanning the phrf-nb rating list (over 500 boats) I see credits as high as 23 sec/mile and as low as 8. In general fractional rigs will get more of a credit because they suffer more without the chute.
