[Alberg30] hull flexing

[Dave Terrell]

big headseas are definitely not the cause. This can happen on fairly mild days too. The hull is painted so I do not think it is easy to say much about the gelcoat unless cracks are showing through the paint job - and I do not think that is the case. When the boat comes out of the water, I can look at it. Thanks for the insight.

Your not pounding into headseas and confusing the shudder with hull flexing are you?
All hulls flex a little - are you noticing gelcoat cracks cracking externally along the hard points where the bulkheads or forebunks are?

? Well my boat doesn't flex at all in a seaway at least that I can feel #296 , deck is thrubolted, rig tensioned the same (I used brians #'s too), new mast beam etc. maybe your deck is riveted and is loose.  I haven't noticed any movement I've had it rail down beating into a fairly heavy sea taking alot of water down the weather side deck over the bow and scooping up some in my 150% UK tape drive. Only vibration I felt was my heart going into high misfire and my white knuckles squeezing the pitch out of the teak tiller..

I do not think so. the rig is  tensioned fairly tightly. I used brian's suggested numbers from our discussion last spring.

Are you sure you are not felling some slack in your rig? possibly the mast pumping a little?

You can feel it in the hull. I am not sure if vibration is the right word, but there is a kind of feeling, a sort of shuttering, maybe.

How does one tell that the hull is flexing? Can you see the inner walls of 
the hull rippling? Do other boats sailing alongside tell you? Ed. Schroeder
