[Alberg30] hull flexing

[bob]

What are Brian's numbers for rig tension?
 
Are they located in the manual or available on the A30 website?

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.
