If you can find a ramp...Cedar Key, or Inglis, you will have quit a ride to get to deep safe water.....like 6-8 miles out.
while i was in Cedar Key last may, there they had a historic low tide. It was not that bad. I did not hit bottom unless i was exploring too close to islands. It was not hard to stay near the channels, and again ... there was very little power boat traffic.. it was very beautiful and i would even recommend it as a nice place to see old florida and sail in some unique areas.
There was a TON of parking and ramps available (both at the marina and along the entire waterfront near our hotels "the far awway inn"
Small boats gathering on an island
super low tide, wasn't that bad to handle.
