Ok, sure it's a bulkhead but my question is = is this normal?? or is this a sign the boat is ready to "Snap" from excessive lateral-stress or should i say "longitudinal" (bow to stern) stress?
Pardon my vocabulary i'm no engineer..by any means.

I had an older P&D that i was beating on and had an upper stringer (past cockpit towards bow) let go that allowed a tear in hull and i almost sank her....
S... experience - especially waiting for SeaTow while we were sinking as they couldn't even find us because i called in from a cell phone.. (don't do/FYI).
My girl at the time was projectile vomiting over the side thinking we were going to die..i had to remind her we were only in 20' of water and could simply swim to shore.
Needless to say (for many obvious reasons) we are no longer together... lol..



Thanks

Both my cigs have same thing, normal

My old Hatteras has 1 ripple on both sides like that. Exactly same spot on both sides. Pull a hull out of the mold it is perfectly straight-assuming mold is. Then you start attaching bulkheads, stringers, knee braces, etc. And they shift or shrink a bit. It'll cause those ripples every time. One of the reasons to stay away from dark shiny hull colors...

I saw similar imperfections in a brand new boat and was assured by the manufacturer that this is normal, they call it a post cure. It was explained to me that it happens when the hull is pulled from the mold before it is completely cured, then fitted with framing and bulkheads which create tension on either side of the frame as their bonded to the hull. As the structure continues to cure if pulls and creates these types of inconsistencies in the hull sides.

Naughty Kitty is right. When I was a kid and worked at the local marina, I was told that cheap boats are laid up and pulled from the mold in the same day. Then as they finish curing they develop waves in the hull. Depending on how high end or custom, a better boat will cure in the mold from several days to weeks. Next time you are at a boat show, look down the side of a boat like a Sea Ray, then go take a look at a Formula, Cobalt, MasterCraft, etc. Night and day difference in the straitness of the hull. Obviously yours is from a bulk head, but the same principal applies. Either way, it's not going to break in half.
