Portsmouth Handicap

My local fleet uses the Portsmouth Handicapping system. The 75 they're applying to my times seems very punitive; I'm finishing (short) 20 - 25 minute races some 4 or 5 minutes ahead of the second boat, and 10 minutes before the last of the fleet crosses, and getting corrected down to 8th place out of 10 or 12. Seems unreasonable, especially since we've been sailing her well. Is anyone familiar with this method? Is the 75 handicap correct? Any thoughts would be appreciated.

75 compares to a 118-119 PHRF. I sail 116 at my club.

75.0= 120PHRF on the D-PN /PHRF conversion chart.The base D-PN for the J80 ODR is 74.1, about 114 PHRF. Does your club use wind modifiers? the J80ODR numbers look like this:
0-1 D-PN 75.0 ( 120PHRF)
2-3 74.4 ( 116PHRF)
4-6 74.1 ( 114PHRF)
5-9 68.5 ( 81PHRF)
The first numbers(0-1 etc. are Beaufort Wind Range) The first three wind range look about right, but the 5-9 seems way out of line. Sometimes the Portsmith can be really off on some boats. An Etchell, for example rates 76.4 in the Beaufort 5-9, about a 128 PHRF, which is way too high for that boat in heavy air. If your club is not using the wind range modifiers, don't hip them up!

At a Beaufort range at or above 5, the J/80 will be planing all the way downwind. Much above 6, the boat will be flying if you can keep the mast out of the water!

I hope you are using PHRF sails in this racing. I rate 126 bouy and 114 random leg, 108 Offwind, it doesnt matter what the wind is. My PHRF Spinn is 900 sq ft +, and use 155% haedsails up to 13 knts. true wind, with the roller furling.
