First ... Proposal submitted... Draft report submitted... waiting for feedback from two readers.
Good, trust it will get good reviews.
They get the formula wrong.
The concepts for rating formulas are similar (
link Rated Length, Rated Sail Area, Rated Weight). SCHRS is somewhat published, but not in Excel (?).
The area qualifiers are open to cats 22 feet and under.
Big cats might be a non-issue if defined by 22 ft LOA; weigh the crews & boats. Early Nacra F20.Carbon results were mush under SCHRS. Later, the F20's started correcting towards the front. The debate item might be big cats as defined by F18s vs. Prosail.40's and D-Class cats.
fat boys don't get fairly rated on Texel or SCHRS.
The sailors have to think it is fair: Weigh the Crews, it makes a difference. Normative arguments are about light air, can't have a light enough crew, heavy air gives an advantage to those with high Declared Crew Weights.
PHRF for beach cats could work..
Uhh, suggest use standard TCF's from Texel or SCHRS. PHRF TOD numbers get converted by local Race Organizers with Many Variants of conversion factors, from Monohull Assumptions, to a TCF that is non-aligned with SCHRS or Texel.
There will be conditions that favor one boat over another, suggest:
Heavy air, long boats with little Sail Area will generally do well, all things being equal.
Light air, never enough sail area on short boats will do well.
There are balanced courses for the races under discussion, non-balanced courses (long-distance) may cause an issue.
Curved boards will be a debate item to rate, suggest: a possible benefit in a breeze, a possible liability in lightish winds. The early Nacra F20.Carbon races in Europe were not pretty; corrected times improved with time in the boat (sound like a one-design?) from my limited view of the data.
