Local knowledge

Old Harbor is the postcard side of Block Island — the ferry landing, the Victorian hotels along the bluff, and the shops and restaurants all a step off the dock. It's a marina stop, not an anchorage.

Tie up inside the breakwater and you're in the middle of town, which is the whole appeal. Reserve ahead in season and take a slip; there is essentially no room to anchor. In any easterly the entrance works and the basin gets rolly — most cruisers looking for a settled night round the island to the Great Salt Pond instead.

Come here for a night ashore with zero dinghy work, then move to New Harbor when the wind goes onshore.

Hazards & cautions. The basin sits behind a breakwater but a strong easterly sends surge through the entrance — uncomfortable to untenable in an onshore blow. This is a dock-and-go harbor, not an anchorage; anchoring room is minimal.
