Hi Mike
Think that is a temporary state ,--just as the latest hottest class is now ,--Javs ,--that continues to change and evolve ,--
Formula would be no different ,-catsailors could keep the same boat and update and modify it periodically rather than having to buy a new """one design"" to stay competitive .--
When I raced H-18s in huge fleets back in the 80s you had to have a new boat and sails every 2 years or did not stay competitive ---I owned 5 different H-18S ---WHEW !!!
FORMULA WOULD BE A VAST IMPROVEMENT --
Basic philosophy of the individual comes into play ,--
are catamarans about sailing at high speed and developing better sailing craft through racing and the development of better gear rigging sails and hardware set-ups along with sailing skills ---
or do you want all improvement -development to stop with your boat and supposed one design ---with its ever changing sails -updates and new mfg rule based boats and gear only --???--
O D can work but look to A Class and Tornados which allow development ,--and A s which allow any builder ,--they are by far the most interesting and advanced cats ,--but no chutes ,-
From there it is a matter of degree of change one wishes to accept ,--all continue to change ,--
If you want no change ,--well race the old floating bathtub type dingies at 5 top speed ,--its fun but ,--
For me cat ailing is the challenge and quest of developing skills and a boat to compete ,---each year I try in the Worrell to compete with the best ,--it is the ultimate test of seamanship and a great adventure ,--
to each their own ,--but do not hold others down sighting limited veiwpoints of a particular o d as a model for all .
there is so much more .-
have fun too
Carl
