PHRF Rating Questions

[jdubes]

I'm trying to answer a few questions on this PHRF rating sheet for my boat.

Can anyone help answering these questions.

1. Keel Ballast Weight?
2. I=Foretriangle Height?
3. J=Foretriangle Base?
4. P=Main Luff E=Main Foot?
5. ISP=Spinnaker Halyard Height?

Thanks Jason

PHRF is intended for keelboats. Smaller boats like the Day Sailer use the Portsmorth handicap. You can find a PHRF conversion in the Portsmouth Yardstick on the US Sailing Web Site.

If you really need those numbers:
1. Keel Ballast Weight? The Day Sailer doesn't have keel ballast. The centerboard weight is max 25lbs.
2. I=Foretriangle Height? - measure from the partners to the forestay hounds.
3. J=Foretriangle Base? - measure from the stem fitting on the bow to the partners.
4. P=Main Luff (see class handbook on this site) distance from band #1 gooseneck to band #2 on the mast.
E=Main Foot? - see class handbook. (gooseneck to black band on the boom.)
5. ISP=Spinnaker Halyard Height?- measure from partner to spinnaker halyard block.

Your PHRF should be around 262. It will vary a little depending on where you are.

The US Sailing table to convert Portsmouth D-PN to PHRF is here:

The Day Sailer's DPN is 98.5 = 261 PHRF.

Hope that helps.
