holder 12 with water in hull

i read in another thread that water in the hull may be absorbed into the hull. i am looking at buying a one but it has some water in the hull. Should i pass on the boat? Everything else is in good condition.

Missing the drain hole? You should be able to drain the hull. The plug may not have been installed or is not drilled deeply enough.

Not sure about drain hole, I can figure that out though. I'm more wondering if I should buy the boat if it has had water sitting in the hull for a long time? Can the water soak into the hull of this particular boat and ruin it? I read on another post about the water "soaking into the hull".

The Holder 12 is not the same as the Mono Cat 12 that had a foam core that absorbed water.

Be sure all of the parts ae with it. You can see damage in the gel coat of water has absorbed. Generally called osmotic blistering of the gel coat. Round bubbles popped up on the surface.

Flip the boat over and tap/press all over the bottom. If it's soft, then the fiberglass/sandwich has deteriorated and I would suggest you pass. Storing the boat with water in the hull for long periods is never good for the hull. It's always best to pull the plug out and tip up the bow so any water that gets in will drain out.

Great suggestions! Thank you! I will check it out with those suggestions.

I have a 1984 Holder 12. I printed out a manual for Holder 12s from the Hobie website which seems to be for a newer model since it shows a drain plug in the stern. My boat doesn't have that plug. After a recent rain I noticed water sloshing around in the hull. I drilled a hole in the stern and some water came out, but not much. The bottom of the deck and the top of the hull are only about 1" apart on this model (in the exact middle of the boat) so I had to drill about 4 inches towards the port side. However, no matter how high I raised the bow only a little water came out of that hole. I have 3 ideas about what to do next and hope someone can comment on them:

1. Maybe there is some junk inside the hull which plugs the hole I drilled from the inside. I plan to test this by putting a long dowel in the hole and see if I can get some debris and/or water to come out.
2. I can drill a hole in the bottom of the boat...this means that the drain plug could get scraped easily...I really don't like this idea much and have no idea where I'd drill since I failed to get much water with the last hole.
3. I could flip the boat over and see if any water comes out. This idea may work, but I'd probably have to do it several times each summer...not too practical...the boat isn't THAT light.

So any ideas?
