Hunter 23 help

Hello,
I have recently come into a 1989 Hunter 23 wing keel. The boat has been sitting on a trailer for the last 4 or 5 years but she is generally in good shape.
I grew up sailing small boats like an Albacore or CL16 at summer camp, but I am new to bigger boats like the 23. There is a piece on the interior that looks like it needs to be replaced and I'm wondering how big or urgent of a job it is. I'm not sure what this piece is called or what to look for. I suspect at this point, it would need to be fabricated to replace.
Thanks in Advance.

That is called a knee and it does need to be replaced. It appears the chainplate was leaking and damaged the plywood. You will have to cut this your self or have someone cut it for you from marine plywood.

I'd spend some time learning how that knee attaches to the hull and underside of the deck. I would do my best to template it including trying to locate the chainplate position. It probably won't come out in one piece and then it will be too late.

Thank you. Is the knee a critical structural piece? I figured that plate was leaking and caused it to rot. Is there any wood (that you know of) above or adjacent to the knee?

Yeah, the knee is pretty important. It transfers the forces from the shrouds down into the hull. If it fails the mast will come down. Not sure how Hunter installed this knee, you'll have to peal back the carpet to see. It should be tabbed into the hull with multiple layers of fiberglass. You'll need to remove that tabbing by grinding and then reinstall more glass and epoxy to secure the knee. The alignment and placement is also important.

Thanks for the detail.. Has anyone here replaced one of these arched knees before? Is there another forum I should post in?

While every boat model is built a little differently, it is mostly a variation on a theme. There are only so many ways to build a production sailboat that works. On sailboats chainplates are either connected to a bulkhead, a knee, or to the deck depending on sizes and intended use. At least for chainplates attached to knees or bulkheads, the drill is the same, tab the knee or bulkhead to the hull to transfer the loads to the hull.

The carpet is just glued in place, it needs to be peeled back so you can see how the knee is attached. Then it is time to carefully remove the old knee to preserve its shape as much as possible, remove the old tabbing, and install the knee and tab it to the hull. That's the broad overview of the repair.

If you are anxious about glassing in the new knee and using epoxy, then there are good resources out there. West System epoxy has a ton of information about fiberglass repair. Andy Miller's BoatworksToday YouTube channel has lots of videos about epoxying and glassing, and TotalBoat.com also has an extensive tech help section. Spend some time with those resources and you will gain some confidence in doing the repair. Working with fiberglass is really simple, it is hard to screw it up if you have done your homework.

I was a Hunter dealer who introduced the wing keel 23
Wing keel it forgot how that pice was attached. Your best bet is to talk with either Mike Thomas or Al Fooks at this forum store who are former Hunter employees and have a build list of parts for the 23. They w pork now at this forum store. Suggest talking with Al

Thank you. I'm not sure how big or small of a project it is. I think it will be manageable with some of the advice and resources others have posted here. I'm new to keel boats, so ive never done this kind of project before.
