I'm doing a cruise May 18-21 out of Rock Hall, with st. Michael's as one destination. I'm reading "Cruising the Chesapeake: a gunkholer's guide" and getting a profusion of ideas. Is it worthwhile to go through Kent narrows to get there (shorter distance), or too tricky due to shoaling? Maybe I could go one way (it will be fun to sail under the Bay Bridge) and come back the other? Also, I've heard the marinas in St Michael's are expensive, any nearby marinas/anchorages that you advise?
