hi philippe, oliver from Mallorca- would you know the rigged weight of a micro 18? regards --- On Sun, 9/28/08, Philippe DE TROY <philippe@detroy.org> wrote: From: Philippe DE TROY <philippe@detroy.org> Subject: Re: [MicroClass] Re: Yardstick number for micros To: MicroClass@yahoogroups.com Date: Sunday, September 28, 2008, 10:27 PM Back on this old topic...   A German competitor entered the 30th Micr'Eau d'Heure and declares his boat as a "Gem with a Cruiser's rig".  He sent his national measurer a setof measurement, but after some exchanges, it appeared that the boat was not a Gem, but probably a Jones Micro 18 (this is the boat described on http://www.microcla ss.org/forum/ viewtopic. php?p=3398)   I'm searching the Stour sailing Club Galleries, and on http://www.stoursai lingclub. co.uk/Images/ Gallery/Regatta% 20Day%202% 20035.jpg, the 4 boats from the left are familiar to me, and identified as Gems.  The fifth one, on the right side, should be a Jones... (someone confirms?)   Then, apparently, the rig is shorter indeed, but for Cruiser, the Mainsail Hoist "P" is limited to 6,85 m (or 22ft 5in) and mast length 7,70 m (or 25ft 3 in) Data for the Gem are P=7,25 (23ft 11in), mast length unknown, but limited by Micro Class Rules to 8,20 m (26ft 10in)   This gives, on paper, a slight advantage to the Gem.   According to the French Handicap National (HN) TCF system, the only element of comparison I found in addition of the Gem (PY 1069-HN 0.6973) is the First 18 (PY 1111 / HN 0.6466)... The PY of the Swift in the Byron software table seems right, related to the First as they are believed to be similar in performance, but the Gem could be too high (equivalent of HN, compared to the First, should be 1029! But there are other boat types in the range of PY 1051-1111, common to both tables, and most of them (Centurion 32, GK 24, J 22, Sun 2000, Shipman 28, Ecume de Mer, Trapper 300, Jouet 760, Dufour 2800, Trapper 500, ...) ALL having a TCF in France between 0,73 and 0,75...  This is the TCF of a Micro Proto (Hot Boat, L'Arte), NOT for the Jones or any production Micro...     A first conclusion ofthe comparison of the tables is than Byron software over-estimates the performance of a Micro by approximately 3 to 5 minutes per hour (except for protos, but HN is based on modern boats with carbon rig) Anyway we don't have more information about the Jones Micro 18, but personally,based on 1069 forthe Gem, I should not give less than 1096, probably 1115, but also change the Swift to 1143 and the First 18 to 1152...   Phil   ----- Original Message ----- From: Peter Halliwell To: MicroClass@yahoogro ups.com Sent: Thursday, September 06, 2007 12:01 PM Subject: RE: [MicroClass] Re: Yardstick number for micros Thanks everyone...thats good enough for me.
