used in some of the canting keel racers. Possibly also America's Cup
boats. Being racers, they are looking for the thinnest possible strut.
Metal ballast dropped into a fiberglass keel was one of the earliest
ideas when contruction went to fiberglass. I don't know why it's not
the usual practice now. Most of those boats had longer keels of lower
aspect ratio than today's boats. Fiberglass is pretty flexible, and
perhaps high aspect ratio struts bend too much. The calculations are
I wonder if it would be possible to buy the strength member off the
shelf, and add the fairing to make it hydrodynamic. For example, a
4x3" steel box beam with wooden nose and tail.
