I read it a few years ago. Just looked again... Apparently there was a fire in the hold in a coal bin.

You mustn't believe everything you read/see on the Internet.

Anyhow how does a fire on the Titanic relate to hull stiffness!!

It is correct, that flexing is not positive. The comments by several people about metal boats flexing were made as an answer to the statement that these boats do not tolerate flexing. They do.

All boats flex to a certain degree. Flexing is a negative because boats have to be relatively stiff due to rigg loads. But it is impossible to eliminate flexing altogether. Boats would be much too heavy. As long as your rigging is tight through the waves the boat does not flex excessively. Boats built in the 60s have very little flex, as experience was gained with the materials, boats got lighter and have more flex. We are talking small amounts of flex here, though.

The problems with reinforcing boats is not to create hard spots. Everything has to taper in the right way into the adjoining structure. With some thought into it, reinforcing a hull is possible, but it needs knowledge..
