Newbie Question About Damage Descriptions

Could some one take pity on me and explain what "beer-canning" damage is n a fiberglass/composite boat? I searched the internet and could now probably brew you some beer, or build something from beer cans but can't find a good definition. Is this a terrible thing?

I can't speak for Fiberglass boats, but on metal boats it is the dishing inward of the hull between the ribs, indicates flexing of the hull usually in older boats or insufficient support in new boats. Depending on the degree it is a bad thing. In metal boats there is a level of deflection allowed. Once a hull starts beer canning it only gets worse.

"Beer-canning" is when the envelope of the hull has expanded in and out like a beer can for whatever reason, and has lost its structural integrity.

Perhaps your Surveyor meant “OIL canning”* which is excessive flexure or deformation of the hull (as Captain58 indicated).

See also David Pascoe’s two Hull Design Defects articles:

Marine Surveying : Hull Design Defects - Hull Failure Part I - Boats and Yachts Surveys

Marine Surveying : Hull Design Defects - Hull Failure Part II - Boats and Yachts Surveys

So ➥ * Let me google that for you

You are right Gord, beer canning didn't sound correct, but I had a brain fart, and forgot the tech. terminology, I think I may be getting "Ole Timers".

Beer Canning is a more social form of racing, usually just before sunset on a weeknight, where no one is allowed to amp out. Oil Canning is what happens to a boat without a stout enough hull. It doesn't always imply structural damage. Some hulls are just built with too much flex. But oil canning is never a good thing, and beer canning almost always is.

Gordon,

Thanks very much for directing me (and others) to Mr Pascoe's work. This is really good stuff! Actually a bit frightening... but his info does give some professional input to the interminable arguments that populate these fora.

A few hours spent absorbing his entire publication will be well spent, and has now got a high priority for me.

Cheers,

Jim
