<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.
