Big hole through side of a cat.

Looks like an old Iroquois catamaran .
How do you reckon a modern production cat would fair with a hole like that in them?

Re: Big hole through side of a cat.

Great photo. Can you post the source please? Is there an associated news article?

Not sure how far into the timeline it was taken but she doesn't look excessively down on her lines and is still sailing, albeit in survival mode.

Still, that is much better than having the boat sink from underneath you.

Most modern production cats, regardless of where the original ingress of water started, tend to end up settling awash but not sunk, stern down, because that's where the diesels and sail drives normally are, and unfortunately the engine compartments aren't always sealed as well as they should be causing them to flood eventually.

Often the water then comes up the stairs from the hull and into the bridgedeck and cockpit too.

Still better than totally sinking, but with a bit more thought and work during production this could be mostly avoided.

Re: Big hole through side of a cat.

Would be nice to know more about it, including the source.

Doesn't appear to be photo-shopped (why?), but some of the details around the hole are weird.

Looks like the hole into the interior is much smaller; the dark triangle in the upper left corner of the damage. Can't be sure but looks a lot like some kind of skin/core delamination.

Certainly not an enviable position to be in, regardless.

Re: Big hole through side of a cat.

A bit of gaffer tape and a new center board should have that shorted out. Apparently they made it to safety.

After applying Google translate, a couple of posts seem to think that the outer part of the sword (daggerboard) case was torn off. We're looking at the inner side of the centerboard (or daggerboard) trunk. One post said it should have kicked up on impact.

Well certainly not well. I would give my boat 30 seconds following being holed like that, if that long. Best to avoid such a colossal hole, it gets in the way of the proper functioning of the hull.

Interesting, so not actually a hole in the hull. Apparently they had hit something. Fortunately the daggerboard/centreboard was knocked out and not into the hull - that could have been a flooding hole.

I guess that after reading the article it is probable that a modern production cat would not see its outer skin peeling off. This is a case where quality control in a large production facility might have caught the issue.

My understanding is that the Iroquois 30 has kick-up aluminum centerboards. Perhaps the starboard board was jammed in the trunk - and then the boat was involved in a hard grounding.

That looks like way too large of a section gone to be a dagger board trunk. Especially for that size cat. I am wondering if that cat was somehow built with the wetted or flotation part of the hull sealed off. Or voodoo. Strange.

I don't think it is really a daggerboard trunk, I think it's a centerboard trunk, especially since there were remarks that it should have kicked up if they had run into something head on. A centerboard trunk would be pretty big.

Re: Big hole through side of a cat.

In the thread relating to the image in the German forum people asked why the board did not swing up.

Actually, our boat has a very similar center board trunk.
Last year we managed to break our board in its down position. It broke sideways at the edge of the trunk due to overload when being hit broadside by a larger wave. I did admitting skimp a little on the laminate over the foam core.
Now we have a much stronger wooden board.
When a large pivoting centerboard is under load its hard to move. If you hit something with the leading edge it might have a good chance to come up. Sideways overloading, it won't come up unless you unload it a bit by luffing up.

So, I do think that the boat in the picture lost the trunkwall by overloading it sideways. As the board was stronger than the trunk, it was the trunk casing which gave way.

Btw. this happened a looong time ago. Still, good that they made it into port safely.

Btw two :-) to me it looks like he hastedly put on the lifevest. Surely there was a handful things to do!
