Your best bet is going to be to call the Chincoteague Coast Guard (area HQ from Delaware to Chesapeake) at 757-336-2874.
You should have pleanty of water
at OC, but it is some rough in on-shore conditions, as there is a bar that can break at low tide in any swell much over 8 feet. I prefer to anchor
in OC, as the marinas
near the entrance are subject to surge.
There are no other harbors between the Delaware and Chesapeake you want to try. Chincoteague will work
, but there are no marinas for your draft
other than the town dock
. It is a variable entrance and 6-foot draft
can be a problem inside at low tide, if you get just a bit off-track.
