I copied Captain Sam’s question below from the Net’s “Ask Your Neighbor” page. I thought he might get a quicker answer if I put his text here as well.

Subject: Entering Boot Dey Harbor with 6′ draft Cruising News:
I have been told that Boot Key Harbor can be entered through Sister Creek at high tide with 6′ draft. (mast is too high for main channel passage under 65′ power cable clearance) Has anyone had that experience with 6′ draft?

Perusing your website saw the question about Sister’s Creek with a 6′ draft. I draw 5’8 and would not dare try to navigate Sister’s Creek even at high tide. You COULD but I wouldn’t recommend it unless with the benefit of an unusually super lunar tide.
Sam didn’t say what his mast height is, but this may be of help: What a number of sailors do to remedy the problem of the often drooping communications line (not a power line) is to have someone
up the mast who can push it up out of the way as your vessel passes beneath it. It’s worked for dozens of taller masts over the years. We have very large
schooners that come in here for the Boy Scout trips… tall masts.
I’d also suggest he call the bridgetender, particularly “Lee of s/v Mariah,” who is forever gracious and quite knowledgeable. He would know the mast heights that have used the method I mention successfully.
