Hey Carl,
"Expanded Formula 20 would eventually have an HT category
for a future class of lighter weight larger beam 20s
like the Marstom 20 --Ventilo -10 beam --CFR ht types --Tornado --etc forming its basic specs and rules outline."

This year there were two M20s in the Miami to Key Largo Race, two M20s in the Hogsbreath Race and two M20s in the Mug Race. One of these boats was sailed by Mr. Marstrom himself and the other by an excellent sailing team from Miami. I think you would find it interesting to check out the race results on a boat for boat basis and on a corrected time basis.
