Chesapeake Bay Maritime Museum

Driving membership growth with research-backed strategy.

The Chesapeake Bay Maritime Museum (CBMM) is more than a museum — it’s a vibrant, immersive campus that captures the soul of the Chesapeake Bay. Located in the historic town of St. Michaels, Maryland, CBMM spans 18 waterfront acres and brings maritime history to life through exhibitions, hands-on programs, festivals, and an active shipyard. As both cultural steward and community connector, CBMM is dedicated to preserving the Bay’s heritage while welcoming new generations into its ongoing story.

The Problem

A stagnant membership base despite a compelling story

Despite its compelling offerings and strong brand equity, the Chesapeake Bay Maritime Museum’s membership had plateaued, hovering around 5,000 annual members. Ambitious growth goals — doubling membership and visitorship within five years — called for a bold strategic reset. The museum’s storytelling strength, led by a small but passionate internal team, wasn’t translating into member growth or digital engagement. Limited resources, inconsistent messaging, and a reliance on email marketing were holding back CBMM’s full potential.

The Strategy

From perks to purpose: make membership a movement

Through our audience research and competitive analysis, we recognized a gap in how CBMM was presenting their membership program versus what their prospective members wanted from them. Thus, we repositioned CBMM’s membership not as a transaction, but as a personal investment in the Chesapeake’s legacy. The new brand platform, “Become a Part of the Chesapeake Story,” framed membership as immersive, emotional, and meaningful — inviting supporters to step into an unfolding narrative of community, preservation, and discovery.

We tackled the problem from all angles: reimagining the membership experience, improving marketing channels, and empowering internal staff to implement smart, scalable tactics. The strategy was grounded in Big Sea’s Ripple of Purpose framework — designed to align storytelling with strategic conversion goals.
