Ever do any mechanic work? Have you ever used a brass
hammer to say align a crankshaft that is pinned and
pressed together? The brass hammer head deforms
while the crankshaft counterweight does not. Very
small movement of the counterweights can be attained
instead of the large, uncontrolled movement that would
knock the crankshaft out of alignment on the opposite
side of the spectrum.

This control and the fact the brass hammer is used because
it is soft and does not damage the structure of the crankshaft
as a steel hammer would is analogous to the forces applied
on the hull of a boat if its keel hits an unmovable object.

The same principle applies to a lead keel. The
mass of lead, of course, is the primary consideration
but the softness of the lead to cushion a blow is another
consideration and makes lead a superior material to
cast iron in addition the lead's extra mass.

It is hard for me to believe you've been in the yachting
field very long or done much reading to speak of without
knowing this very obvious and widely known fact.

It's heavier but is it soft enough to cushion possible
impacts with the sea bottom? Since it is used to pierce
armor I've got a feeling it is pretty stout stuff.

S.Simon

Cushion?
WTF are you talking about?


You know, when a sailor runs into a rock or other
hard object on the bottom - maybe a coral head
it is said that lead, being soft, will cushion the
blow by deforming and absorbing some of the
force thus sparing the structure of the yacht.

Bwaaahahahahhahahahahahahahahahahahahahahaa!
Cappy that rates among the most idiotic things that you've ever
written!!


It did not originate with me but I can see the logic of it.

Your reaction, on the other hand, is illogical.

S.Simon

Cappy could you fill me in on how much cushioning I could expect from
say a 4 ton lump of solid lead and how it would achieve that
cushioning?
