I didn't get any reports from the Vero or Sebastian areas yet, but did get this report from Jupiter.

Joe D. sent the photo and the following.

Joe  said, Erosion is minimal for now, wind needs to change direction to have an impact! Wave height good though!

Thanks much Joe!


The readers of this blog are amazing.  They are extremely accomplished and knowledgeable.  I post many of their contributions, but not all of them.  Sometimes they tell me that they don't want their emails posted or that I should keep some comments private.  Even when I can't post something, I'm still glad to get the information and it adds to my knowledge base.   I'm proud to have such knowledgeable readers.  Whether I post their names or comments directly or not, you still benefit from their contributions.


Not long ago I talked about spikes and in another I talked about wood.  Here is an exceptionally good study of a 16th century Biscayan ship.

There are a variety of reasons or any serious detectorist to become familiar with old ship construction materials and techniques.

Here is a brief excerpt from the 16th century Biscayan ship study.

The second characteristic of 16th-century Biscayan shipwrecks is the use of a combination of oaken treenails and iron nails to fasten the hull planks and frames. The treenails are about 25 mm in diameter and the iron nails are about 10-12 mm square in section. At each joint of a frame timber and a plank, two iron nails and two treenails are typically found. The use of both iron and wooden nails distinguishes Biscayan shipwrecks from more northerly wrecks, such as the Mary Rose, which have only treenails and from more southerly wrecks, especially from the Mediterranean, which have only iron nails. João Baptista Lavanha, a Portuguese naval administrator who died in 1620, left a manuscript on shipbuilding which states that in countries whose ships sailed in cold waters, wooden nails were used, while in countries whose ships sailed in warm seas, iron nails were used. He explained that in warm waters, wooden nails were destroyed by taredo worms and each treenail became a leak5. In Biscay, both oak and iron were plentiful and readily used as nails by shipbuilders. Analysis of the Red Bay ship has shown that the iron nails were used...

And here is the link for the rest of the study.


I was listening to the radio and heard what is a very common statement concerning how Southerners respond to cold weather.  They say that your blood thins.  That is not exactly what happens.

Back in the 70s I was conducting research in biofeedback and discovered that the normal response to cold is for the blood to redistribute from the extremities (fingers and toes, for example) to the body core to preserve heat.  I found out that people who lived in South Florida seven or more years, lost that cold adaptation response to a large degree.  So it isn't that the blood "thins." People eventually lose the cold adaptation response.  My fingers really felt the pain of that Monday.


Here are the surf predictions for the Fort Pierce area.  We'll get a decrease and then an increase around Friday if the predictions are correct.  Something good might happen.  We'll have to wait and see.

Happy hunting,
