<DIV><FONT face=Arial size=2>Brian is absolutely right - all weight on the
keel - the side pads should be at the bulkheads and be adjustable
with no actual weight on them. The pads sole purpose is to keep the boat from
toppling. The forefoot pad will need weight on it on the centreline to stop it
from pitching forward - but that is the only one. The hulls are solid glass and
some oil canning can be expected - remember the hull is at least 5/8" solid
glass at the turn of the bilge and gets thicker closer to the keel.</FONT></DIV>

<P>I experienced a similar problem with hull flexing, but on land. The yard
put the aft jack stands in the wrong place and put to much weight on them.
The result was "oil-canning" around the stands. I made them change the
stands...when they wanted to charge me for blocking twice, I threathened to
move them myself, we had an argument, they changed the stands, I did not get
charged, I do not use that yard any more. The lesson is...when the boat is
out for the winter, sight down the hull from bow or stern, and be sure she
looks right, if not fix it.<BR><BR>Mike Lehman </P></DIV>

<DIV></DIV>Dave,
<DIV></DIV>
<DIV></DIV>You don't say what hull number boat you have. If you have a
wooden
<DIV></DIV>beam, is it in good shape or starting to sag? If a newer boat,
does the
<DIV></DIV>head door stick on the overhead?
<DIV></DIV>
<DIV></DIV>Are your bulkheads still attached tightly all around?
<DIV></DIV>
<DIV></DIV>Everything flexes a little, but the A30 is a pretty stiffly built
boat.
<DIV></DIV>What specifically are you noticing?

<DIV></DIV>Hi guys -
<DIV></DIV>
<DIV></DIV>I have A30 #426 and she exhibits hull flexing as well. The
problem is that
<DIV></DIV>our boats were heavily glassed up but with no core material in
the hull.
<DIV></DIV>This means that they are not as stiff as they might be; but on
the positive
<DIV></DIV>side there is no chance of water destroying the hull via water
rotting the
<DIV></DIV>core as we get in decks.
<DIV></DIV>
<DIV></DIV>It is a bad idea to try to bolster the hull with interior
stiffening as it
<DIV></DIV>is very easy to create hard spots that the hull can then crack
around. Best
<DIV></DIV>just live with it.
