On the Hudson River, we use ToT at the club level and ToD for interclub regattas.
The rationale for ToT at the club level is roughly: 1. The RC doesn't need to know the exact length of the course. While we race around fixed marks, the RC boat will move to give us the best approximate W/L course. This eliminates need to know the exact length of the course. 2. While we have 20+ boats split over 2 fleets (spin/non spin) the PHRF range is 57 - 261. ToT is said to give the slower boats a better chance. Not sure why we still use ToD at the interclub level. We use the default A/B values. Advantages for PHRF vs other systems is that it is cheap and easy to administer. While overall numbers for PHRF racing may be down, there is yet to really be another handicapping system that has taken hold and can work easily with local admin. A couple years ago there was a big push for IRC by making it cheaper and easier to apply for an un-endorsed cert, but IRC seems all but dead. I got an email from US Sailing the other day pushing ORC pushing ORC club. But it is fighting the installed base of local YRAs in the US that issue thousands of PHRF certificates each year. A PHRF application is really pretty easy to fill out for even a novice sailor vs the measurement requirements for other systems. Also the money and administration for an ORC certificate is going to US Sailing vs. your local YRA who more directly support racing in your area. Full disclosure I am a member of our local YRA board.
