[Public-List] Stern squat.

[Mike Lehman]

Why not just fill the water tank - 30 gallons at 8lb/gal is 240 lbs...and it 
is below the water line. You don't have to drink it.

Hello -

I feel awkward recommending trim ballast...putting weight toward the ends of
the boat is so against text-book principals.

But with regard to the chain up forward; it's never moved.  It lays in a
compact pile and even pitching in a head sea hasn't stirred so far as we can
tell.  I reckon that potentially it could, but it hasn't.

We did have a tangle up once that we figure was caused by a pile of the
chain which formed toppling over.  We didn't hear it happen but the result
was that it wouldn't feed out until we'd sorted things out.

Would it need to be secured, any more than anchor chain is?

Maybe I could use a whole pile of galvanized chain (on sale it is

I suspect it
