I do not know what the state of naval engineering is these days. As I
stated, my knowledge of naval engineering is tangential at best. I imagine
that fiber composites would have some real advantages in this case, like
the case you stated above, but there are numerous issues regarding the use
of such materials that I know nothing about. There may be some
environmental, damage propagation, and repair/maintenance issues that may
make it impractical to use fiber composites.
