Cruising the Chesapeake: A Gunkholer's Guide 4th Edition My favorite Chesapeake Bay guidebook. While it mentions marinas, it concentrates on anchorages—the kind of places I prefer to spend my time. And in addition to listing shore facilities, it rates each location for Beauty/Interest and Protection. This is the guide you need to really cruise the Chesapeake Bay—a smorgasbord of small creeks and coves. (Note: commissions earned from this link help defray the costs of this website)
