Sailing Classes in Chesapeake on a Cat

[gwmort]

I am looking for a sailing school in the Chesapeake Bay that teaches ASA certification courses on cruising sized catamarans, any ideas?

I took a basic sailing class in college about 19 years ago, and owned a Hobie 18 for several years, but don't have any experience on larger vessels (or ones with motors) or any formal certifications. I'd like to pick up some certifications to go bare boating, but don't really want to go through all the basic stuff again on the little boats I am already familiar with, so would like to get them on a bigger boat which is the experience I need most anyway.

I've seen some week long charter live aboard courses that would work, but time is still a critical issue for me and would prefer something I could do over a series of weekends. I also can't really afford to do many classes at the same time.

All guidance and shared wisdom is appreciated.
