So the assumptions NECESSARY for portsmouth to work..

There is a FLEET of Nacra F17s..
So... is there a fleet... was there a fleet and how big of a fleet of F17s was there ever?


This Fleet of F17s races against a fleet of Yardstick boats... (Hobie 16s, Nacra 5.8's Prindle 19s and now F18s..) So... lets be generous and say... that a fleet is 3 to 5 boats.... Show us race results for 20 races of nacra F17s... racing a fleet of one of these yardsticks. (That is 1/5th the number used to determine a PN rating by portsmouth.... for a wind range.... eg B2 / B3.

Otherwise... you are making an educated guess. In that case, the Portsmouth/PHRF board should meet yearly and guestimate a new rating table that the board believes is "fair".

The pitfall in saying... you will evaluate the handicap system by comparing the results at the end of the year is that you wind up goring somebody's ox with the choice ...based on their season results.

It would be wiser to agree on some criteria before hand and then measure the season against your essential factors.

Another thing you might consider is take the times on your one design classes and then use Sailwave to calculate the rating each boat in the one design fleet sailed to. It will give you some valuable perspective in evaluating ratings tables.

It really sucks when you realize that you just turned in a 4 th place performance on your nacra F17 that equals what a well sailed Hobie 16 would have done. (Bottom line... its the sailor... not the rating that matters)

Perspective on the numbers matters.

Good luck
