Yesterday afternoon, Ed and I had hoped to walk our dogs, Bo and Baron, to the St Lucie Inlet, but were cut off by an incoming tide and a Sailfish Point’s seawall. Having grown up in Martin County, it is amazing to see such changes “right before my 50-year-old eyes…”
Of course when I was a kid there was no Sailfish Point development, no seawall, no apparent sea level rise, just the beach sun-flowered sand dunes and Bathtub Beach changing daily to the winds of time with the remnants of James Rand’s “Seminole Shores” development crumbling…
Today Sailfish Point is here. Its 625 homes are some of the most exclusive in the county. Built in the 1980’s it was developed by Mobile Oil Corporation. The area brings tremendous tax revenue to everyone and to every school in Martin County…if it washed into the sea there would be issues for all.

It must be noted that the St Lucie Inlet itself is responsible for some of this erosion…the inlet was opened permanently in 1892 by pioneers led by Captain Henry Sewall of Sewall’s Point. Naturally the inlet would open and close with tides and time. Opening the inlet permanently now defines our county, and we would not give it up; but as all things in life: there are both positives and negatives to every action.
Today the waters of the ocean are encroaching….and time seems to be speeding up.
Building on barrier islands is not particularly long-term in that barrier islands are meant by nature to turn over on themselves like a conveyor belt. On the other hand, I have been to the Breakers Hotel in Palm Beach and their seawall is right up to the historic hotel and has been for years….We stave off the ocean as long as we can. Much of Florida east coast is built on barrier islands…
What does the Bible say? “The wise man built his house upon a rock…”
Anyway….today I wanted to share Ed and my walk as it is symbolic of our times.
Other than the surreal seawall and encroaching sea….there were many sea turtle nests, marked by the Fish and Wildlife Commission. Many turtles had laid their eggs right up against the seawall! Many of them! I counted at least 50 just in our short walk. Good for the turtles but it seems many nest are doomed to wash away… For thousands of years these turtles have returned to the beaches of their birth to lay eggs. Now many of them literally come up “against a wall.”
I must mention that the people of Sailfish Point are also “up against a wall,” as they have to worry about their homes falling into the sea….Here one sees a sea wall repair taking place. I don’t think the sea wall is that old in the first place.
The most intense erosion seems to be the north area of Sailfish Point, closest to Bathtub Beach….and it is summer. This should be the time the ocean, sands and tides are most forgiving. Winter waves are much more brutal, unless there is a hurricane of course….
The other interesting anomaly Ed, Bo, and Baron and I experienced was the hundreds of sea hare mollusks that had washed up on shore. Ed Killer of TC Palm just wrote a great piece on these interesting, harmless creatures that scientists believe are washing ashore due to cold water upswells and algae shifts in the ocean–their swimming affected, they slow down and are carried to shore by the waves fated to dry out in the sun.
As Ed and I walked back I picked up as many as I could and threw them back into the ocean knowing that really I was only “buying them some time.” Chances are they will wash right back up on the shore. In the end, nature always wins. In time, we like the sea hares, will find this out , but until then it’s a great walk on the beach, isn’t it?

THIS ADDITION CAME IN FROM MY BROTHER TODD: AMAZING!
Interesting blog post!
In the meantime I thought I would respond to your post with a rough video of Sailfish Point while eating my lunch…..
It is a movie of the following:
1. 1935 NOAA Chart – note the jetty already in place
2. 1940 Aerial
3. 1952 Aerial
4. 1968 Aerial – quick. I should have skipped it.
5. 1970 Aerial – note the old “Empire of the Ants” pier and the strange water slick to the south.
6. 1981 Aerial – showing the construction of Sailfish Point.
Look at these two screenshots of the beach just a few months apart late last year—-Todd Thurlow
