Our Rating System
Ratings have been a part of TMCC racing for over 20 years. What started out as some rough numbers, became a ratings formula in the late 70's, and has been fine tuned ever since. Most of our racing is done in fairly protected waters with light to medium variable wind conditions over short and medium distances.
TMCC has always favoured time on time corrections, but we have also converted our ratings to accomodate the PHRF time on distance numbers that started to show up at regattas a few years ago. PHRF has a tendancy to be localized, and therefore should always be considered in conjunction with local conditions. The elusive perfect rating system for multihulls is a work in progress. We know our numbers to be accurate within our fleet, and they are based on more race data than is available anywhere else in the world.
The Farrier boats have not been well represented in Canadian races due primarily to the fact that there have been more affordable boats available. There are more comprehensive Farrier ratings available elsewhere, but our numbers have bracketed them relative to other types of boats. There will always be disagreements, but we're open to any suggestions and/or data. Enjoy!

A few notes about the data. It has been our experience that absolute ratings numbers, while the ultimate goal of most ratings systems, is an ongoing task given the wider performance range of multihulls. We have had the luxury of having a fair bit of consistency within the local fleet, and years worth of performance improvements. Our approach for new boats has been more relative than absolute. We feel confident that we can 'bracket' the performance of any boat fairly accurately, armed with our experience and the ratings information given here.
That is to say, for example, if a F24 showed up for our next race, with a square top main, we could place him faster than a stock F24, and a stock Dragonfly 25, but not as fast as our fastest Dragonfly 25 with a square top main and screecher, or a Gougeon 32.
This still leaves us with the old skipper vs boat rating question, but as the data accumulates you can get a feel for that as well. You will notice that we have two numbers for many boats, a stock rating and a modified rating. This is a 'window' that gives the slowest and fastest boat of that model we have encountered. Assume the modified boat is fully tricked. Also, note that the TMCC ratings are the ones we use as they are the only ones we fine tune regularly, the other information is there as a reference, and is not updated as regularly.
We're currently working to combine most of the North American rating information into one site. Check here regularly to see how the project is coming along. Hope you find this approach useful at your events, and by all means send us any data you may have. We'll be happy to add it to this site!
