When I walk forward in the head or stand (hunched) in there, I can feel the hull/cabin sole flexing under my feet.

When I walk stand by the port settee toward the aft end, I feel the cabin sole flex.

Does anybody else have that?

I seem to recall a little flex on my '82... Frank was cutting back on fiberglass. Unacceptable, but given that these boats are built to a price point, I guess it's a given. Worse yet is seeing the water line thru the hull when down below and heeled over.

Mine flexes a little fwd near the stbd setee and a little in the head. I used to think it was BMI related when I weighed 260. Now that I'm down below 200 it still flexes. I don't think it's anything structural, like Sten said, it's probably just a manufacturing cost savings. I toyed with the idea of trying to shore up the area near the setee via the bilge access board but I was concerned about making a hard spot against the hull that might cause more trouble than it's worth.

I get the same thing aboard Confetti in the same places. I have for the almost 36 years I have sailed her. I think its just that Catalina's are not heavily built boats, and the proce point reflects it.

Well... that is true, they flex. I lost one of the wood wedges that was suppostobe glassed in between the liner and the hull. It just fell out.

I was gonna wedge in a few more, from the bilge, but it got way down on the list. Really should be easy to do and thanks for reminding me.

Would that hull flex make you hesitate to sneak your boat from Miami to Bimini in good weather?

Can you determine if it is hull AND liner or only the liner flexing? If it is only the liner, I wouldn't give it much thought.

I seem to have the same issue on my '82; the sole just forward of where where you'd stand in the galley flexes (if you could stand in the galley, which you can't

). It seems that the DPO shot some foam under the sole to 'fix' it and raised the port side of the sole so now one side of my bilge access opening is about 3/4" higher than the other. The access plate doesn't sit right and one screw is stripped.

The boat sat with water in the bilge for 3 New England winters, not sure what effect that had; I doubt it was an improvement.

Seth: I think these posts are about the cabin sole flexing, not the hull/keel.

This is off subject, however I thought it appropriate to congratulate keeldad on his weight loss of 60#, good deal.

I meant hull flex. Sorry, I haven't been drinking yet.

As far as the liner goes, I believe there is no space between it and the hull in the head area so liner flex in the head would be hull flex in the head, but I could be wrong (haven't been drinking yet).

Yeah, good job for getting toward health body weight. I myself am 5'8" and weight about 150lbs. AND my cabin sole still flexes.

Thanks for all the replies guys.

That's the liner. I don't care how heavy you are, you ain't flexing the hull. Oil canning is not a Catalina trait.

When doing the annual waxing, I was able to push against my '82 hull and watch it flex...

Were you waxing below the waterline?

Seth stated the flexing was on the cabin floor in the head area indicating that the flexing of the hull occurs near centerline and below the waterline.
