That giant "Sucking" sound

Hi Everyone
Tom and I are at "Salty Sam's Marina in Ft Meyer's Beach where we'll remain for at least one month. Our trip down here from Tarpon Springs was quite an adventure.
Marsha and Geoff Livingstone, old friends from Barrington now living in Stuart, joined us for 4 days of boating fun. They expected to make the 200 mile trip to Ft Meyers with us, but instead they had a fun filled, rollicking 13 mile sail over 4 days aboard "Cloud Nine". We were stuck in Dunedin Fla for two days because of extremely low tides...because of shallow water we couldn't get out of the marina. So, we went from the Greek town of Tarpon Springs, to the Scottish town of Dunedin...saw the Christmas parade and lots of bagpipe bands..a little Europe in South Florida. When we finally tiptoed out of the marina two days later, at high tide, praying we wouldn't go aground, we all cheered. We happily motored 3 miles down the waterway to Clearwater with Pam at the helm.
As we passed the Clearwater bridge I looked up in complete confusion and noticed two green channel markers in front of me...with a sickening feeling I heard "shhhhhhhhh-rump- squish, squish, squish"...then the boat settled down hard aground just outside the busy channel. I had misread the channel markers and run us aground!!!!
Tom tried to motor us off the bottom to no avail. We just sat there like a boat in a bottle with nowhere to go.
We called "Seatow" the boat company we have a towing insurance policy with, and they told us that because of the severly low tides they would not attempt a rescue until after midnight when the high tide would be higher...It was now 3 pm and a gigantic boat parade in Clearwater was scheduled to begin at 5:30 and we were right in the way of the parade! Tom and Geoff decided to put our anchor in the dinghy and carry it east so the boat wouldn't drift further into the channel. We then sat down to wait until midnight ....all of a sudden...up in the sky...is it a bird,? is it a plane?...no it's super-boat....or at least it was Katie Sue one of our looper boats. They had heard our distress calls and they came to our rescue...proposing that they would get their boat up to full speed and keep running it in front of us creating a big wake that MAY be enough to get us off the hard....So Katie Sue went roaring by us...once...no luck...twice...no movement...three times we felt "Cloud Nine roll a little...on the next pass Tom turned the boat and gunned the engine as the wake wave crested and "Cloud Nine" rolled off the bottom into the deeper channel...talk about cheering and complete relief and most importantly gratitude. A great big "thank you" to John and Betty Lacy for their help.
We followed them into the closest marina to settle down, have a victory drink and watch the boat parade. As for Marsha and Geoff, we laughed at the distance travelled, but they assured us that they appreciate the material we gave them for great stories with which to entertain their friends and family...
