Just thought I would bring this thread back to the top for possibly more debate, now that there seems to be some pictorial evidence that a Jav 2 hull will sink when holed. See attached photo that I borrowed from a post on the Old Forum. It is the Jav 2, sailed by Matt Struble and W.F. Oliver, that was T-boned at the Alter Cup.

Of course, it may be some sort of optical illusion. But there were verbal reports, as well, that the holed hull did indeed sink below the surface.
