Yacht-capable marinas are a distinct category. They require 12+ feet of dockside depth, 100A or three-phase shore power, beams over 30 feet between pilings, and concierge dock service. There are fewer than 60 true megayacht marinas in the United States. Here's how to think about them.
What qualifies as a true yacht marina
Dockside depth of 12+ feet MLLW. Slip width of 30+ feet (most pleasure-craft marinas top out at 22). 100A single-phase or 50A three-phase shore power, with some marinas now offering 200A. Concierge dockmaster, fuel delivery to the slip, in-slip pump-out, secure perimeter, and provisioning support.
The top U.S. yacht marina regions
South Florida: Pier Sixty-Six, Bahia Mar, Sunset Harbour, Miami Beach Marina — the densest cluster in the U.S.
Newport, RI: Newport Yachting Center, Bannister's Wharf — limited summer-only inventory.
San Diego: Sun Harbor, Marina Cortez — year-round, deep, protected.
Seattle and the Pacific Northwest: limited but excellent (Bell Harbor, Elliott Bay).
Charleston, Savannah, Annapolis: midsize yacht infrastructure with regional charm.
Cost expectations
Annual yacht slips at top-tier marinas run $150–$400/foot/month. Transient runs $8–$15/foot/night with 100A power separately metered. Add a season-of-stay surcharge in Newport July–August.
Reservation and waitlist dynamics
Annual slips at the top 20 yacht marinas are functionally waitlisted indefinitely; turnover happens through broker relationships. Transient bookings open 6–12 months out for prime weeks.
Services beyond the slip
Yacht marinas typically partner with crew agencies, provisioners, detailers, and on-call mechanics. The dockmaster is effectively a concierge.
