[quote=samc99us]DK,
I have no doubt that your system has some advantages, especially when trying to rate pretty dissimilar boats like your Corsair F-242 and Blade F-16. To that end I think I need to spend more time looking at the how you are crunching numbers, which is all spelled out on your community website. However, after a 5 minute quick glance I was a little overwhelmed. This is from a guy who crunches numbers for a living, and computes SCHRS numbers for our local fleet as well as measures boats. To be fair its already been a long day, but its not a system that is easy to use for different beach cat fleets in different countries. It also doesn't [i]appear[/i] to have the thousands of race results SCHRS does to statistically back their rating numbers, and you are reliant on a local PHRF committee to generate numbers. I suspect that you are lucky and have a fair and reasonable PHRF committee, but I have seen that go quite the opposite and really erroneous ratings get generated.
I should also state that I don't think SCHRS is perfect. I have found a couple of flaws in the published ratings, much of which has to do with discrepancies between boats on different continents. I.e Inter 20's in Europe were sold with a smaller sail plan than the U.S I-20, and we are talking about a 12+ year old boat so its not always easy to trace the history. I also will say that it may not rate boats that are drastically different than an F18 fairly, but I think it tries to do so and in general produces reasonable numbers for beach catamarans.[/quote]
