T&T: Marathon Depths

[Russell Davignon]

Any of you folks been into Boot Key lately. I previously asked about marinas in Marathon but now my focus is slightly different.  I have 6' 6" draft 44' steel hull and a reservation at Sombrero Marina.  Dock guy says I can make it with the tides but the more I look at maps,  the more I wonder as there are no depths printed for that far into the bay.  Anybody with current practical navigation expereince lately??? Thanks Russ Davingon
