We are at a marina with floating docks - thanks to people who recommended Brunswick Landing to us. We've been experiencing tide differences of more than 8 feet. It would be really hard to keep up with these tides on fixed docks twice a day! (There is plenty of water in the slips even at low tide.) We took pictures at high and low tide looking toward the land and toward the water so you could see the difference. That ramp going up to the covered pier gets pretty steep at low tide.
