Sister Creek info needed

[F51]

We would like to get to Boot Key Harbor at Marathon. We are too tall (68') for the overhead cable at the old bridge (65'). In looking at Sister Creek, the chart shows 5' MLW at the entrance. There is approximately a 2' tidal range, so we should be able to get our 6' draft through there at high tide. But this is all "book learning." I would like to get actual experiences from those who have made it. I spoke with the marina and they said 6' drafts have made it thru at high tide.

We have been in and out of Sisters Creek several times in the last few months. The depth at low water at the entrance MARKERS, not the creek, are 5'6: MLW. Plenty of depth in the creek just stay in the middle. You can do it at high tide. Chuck
