Yes, we took our old C-30 in there at ebb. There are soooooooo many rocks in there that are uncharted it is simply amazing. We now anchor in Long Cove or near the entrance and take the dinghy in. We once saw a boat that had "been in numerous times" wind up perched atop a rock they never knew was there. In the middle of the night the tide dropped and there they were precariously balancing on this rock.

We have probably been in about 20 times now via dinghy and only twice seen keel boats inside. Once the keel boat was on a rock....

The entrance is STREWN with Volkswagen to RV sized erratic boulders and the Cruising Guide is anything but accurate as to including ALL of them. If you follow the path you will note that your boats under-body is mere feet from HUGE barnacle encrusted erratics. The current also does not ebb in concert with any of the tide tables so best to physically wait it out. Entering at dead ebb is really preferred.

We won't ever take the big boat in again having done it now in the dinghy, at many differing tides, and seen all the erratics close up. Once was enough. We now just go in via dinghy and lobster bake or swim off one of the many beautiful islands.

This image, not mine BTW, really sums up the entrance.
