I'll add whatever events I learn of, but hopefully others will do the same. The official Div 11 site has zero events on the calendar and dead links for some of the fleets. Looks like there has been little work on it in years.
The "Calendar" tab on the Div 11 page is always blank (at least I've never seen anything on it). It should probably be removed from the page. The regatta schedule is posted in the "Regatta Info" tab (although it still needs to be updated from 2013 to 2014 schedule). Really the only "events" in the division are regattas.
Most of the communication within Division 11 has been through the Yahoo Group lately.
This year's regatta schedule is:
Gunpowder, May 3/4
Sandy Hook, May 31/1
Shore Acres, June 7/8
Rock Hall, June 21/22
Hobie 14 NAC (Sandy Hook), July 10-12
Barnegat Breezer, July 19/20
Spray Beach, August 23/24
Rehoboth (RBSA), Sept 6/7
H16 NAC (Lewes, DE), Sept 22-26
