15869Re: Concrete keels?
- Dec 2, 2001I must agree with Bill here. There is a reason the old timers use
lead most of the time and most of that reason is density. For the
price and availability you can't get much denser. Switching a micro
keel to cement you would have to increase you depth quite a bit to get
the same righting arm. There is another reason to use lead and it
depends on the ballast location, not being familar with Micro's I
don't know if this applies. Lead is soft and if external (bolted on
the bottom of the hull as apposed to poored in the hull) ballast is
used it can make for a very good shock aborber against an unfortunate
bump on something hard like a rock. Iron can send a terible vibration
through the hull affecting the keel bolts, cement could crumble and or
vibrate the keel bolts(or what ever) which would be very difficult to
repare. Any dents in lead are easy to repare.
