Thats a really good post. I am quite familiar with cement, concrete etc as I have been employed in the construction materials quality control business. This, is not an issue about ferro cement. It is stated that Anne is:
"...likened the hull to a sealed steel and fiberglass bottle."
However, according to the construction series there is NO fiberglass involved. Anne is:
Welded-rebar frame, chicken wire mesh, and a mixture of POLYESTER RESIN and something called Ferralite. No more, no less, no fiberglass, no ferrocement.
Here is the exact quote from 1000days site:
"We mix a white powdered product called ferra-lite with polyester resin, and push it through the mesh and steel until every gap is filled"
Ferrocement is a mixture of cement, sand, and water... When you add crushed rock you get concrete. My boat is concrete actually.. well the keel is, 5000lbs of concrete and iron.
In the blog Capt. Stowe states the boat is leaking... not so much like a sealed bottle. They did make a report as of today. I just hope they make it safely 1000 days out or not.
I also noticed I spelled Tantra wrong.. I apologize.
