Hi Colin & Fluffy
Also there are some good articles and info on the U K
fORMULA 20 part of the site ,-a good one by Dave Walker from the Bala sailing club .
http://www.catamaran.co.uk/IF20/articles.htm We may have slightly different set ups on the I-20
generally grommets are already placed in the tramp for the mast rotation control leads at the mast base area of the tramp ,-a small block is attached to the front crossbeam for spin halyard in front of the spin cleat ,-and spin blocks lead from mid hull location near stays to forward beam blocks then back in a continueous sheet . Most all use snuffers ,-except in distance races like the Tybee or Worrell type ,-then spin pole with a tramp bag ,--
I,d like a mid pole snuffer and numerous other modification for ocean distance races ,-but we don,t have the Formula 20 class going quite yet here ,
working patiently on it also ,
-N A version rules outline to date -
for any N A F-20 potential catsailors interested -
