Its not what sailors would LIKE.... Its about whats available in your area and how you are going to manage this circumstance. Individually and as a club putting on events.

Case in point... the I20 fleet. From what I can tell they have had ONE 10 boat regatta this year (Florida last week).
What 10 boat I20 triangle regatta have you sailed in Michigan this year? Whats your plan... sell your I20 to a rec sailor and buy an F18? Perfectly reasonably mind you... Its just not my choice.

The Michigan solution looks like they collect times and print out the overall results plus the 5 boat I20 results. You pick which one matters to you. Atleast it maximizes the fun in going racing.

My proposal is to publish in your NOR that you must have 10 boats on the water or you will be combined into a suitable portsmouth fleet and scored as a one design/formula.
Basically this means purchasing three extra trophies per portsmouth fleet created. Collecting times and running sailwave.

Hope to see you at Catfight
