We spent a very enjoyable night at Cedar Island - just a stop-over on our way up Long Island Sound. The entrance channel is a little scary at first because there are no buoys shown on the chart, but in fact it's well marked and we had no problem coming in or out.
I called the marina on the VHF on our way in and they came right up with detailed directions to our slip. Sean was waiting for us at the dock to help with lines & shore-tie as well as information about the marina and the local area.
This is a nice marina with floating docks that are in good condition, a friendly & helpful staff, in a well protected harbor. We'd definitely stop there again.
