Well, of course, but that's not the point, is it? The point is that
properly designed, implemented and installed, wood floor joists are
strong enough. And that's all they have to be. As to the flexing issues,
my house has built-up "truss" joists of wood, and my floors don't flex
to the point you'd notice it. Further, large areas of the main and
second floors of my house are covered in ceramic and marble tile,
installed the usual way, and we have no cracks in the mortar or tile. If
there were substantial flexing of the wood subfloor (held up by wood
trusses), we'd have some mortar cracks.




An all composite, no wood boat is a lot better than one with wood in it.

Again, I suggest you take that up with Grady-White and other
manufacturers of small pleasure boats who continue to use wood in the
construction of their boats. GW can build boats any way it chooses,
without worrying too much about price points, since it already is at the
top of the price chart. It chooses wood.


Just because a lot of boats have been made with wood does not make it good.
It just means it is cheap and easy.

It's easier to build a small boat's structure of composites or foam. The
stuff can come out of a mold and be glued into the boat. No special
skills required.
