Water logged hull

Hi there, I was at the dock today,some of the old timers say that a water logged hull on a 23 foot sailboat can add as much as 1000 lbs. I cant belive this is true, what do you guys think ?
I hope it BS anyway

I'm sure some of our more math inclined persons will come up with a better answer but at a rough 8.5lb per gallon, 1000lb would mean that a hull has absorbed about 117gal of water. I find that hard to believe also on a 23' boat.

The amount of water a hull can absorb is around 2 - 3 %. If it is 1000 heavier that means the boat body is 33000 - 50000 lbs.

It depends, was this a wooden boat or a fiberglass boat the oldtimers were talking about. Witha wooden boat, yeah, I can believe that. With a fiberglass one, I doubt it.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Not to mention if you have 1000 pounds of water in a 23' fiberglass hull your boat is screwed.

who is staring at the sea is already sailing a little

The real answer is it depends... is the hull cored and if so, with what?
A wood cored hull (there are plenty around) can absorb an incredible amount of water.
There is no meaningful answer without knowing more detail.

All I know is; I can bring 2 wild women onboard and a ton of drink and food and my boat can weigh 2200 pounds more.

Sometimes we can tell the truth and sometimes we may exaggerate in general. I remember when mosquitoes were so bad they carry off cows, but, was that true?? Either way, the mosquitoes were bad enough people were miserable!

May not believe what said, but, I understand the concept!

Hope this help!

If I had a nickle for each piece of bad information I'd heard related by some "old timer" down on the dock, I'd have... well, I'd have quite a few nickels.

My personal fave? "Boats are faster with a layer of slime on the hull, just like fish."
