This is the Mac. web site. It is very interesting to read. This is not a boat I would consider. Here is some stuff in there.
"If you are operating where the chance of outside rescue is slim, where conditions are rough, or where the water is cold and uninviting, fill the ballast tank. You will go slower, but you will be a lot safer. A full ballast tank gives greater safety."
Are they saying it is not too safe with
tanks empty? Here is another blurb in there.
"If you have to sail the boat without ballast, do not cleat down any sail control line. You must hand hold them and release them quickly if the boat tips excessively. Always make sure that the line is untangled and free to run out to its end without jamming."
