hauling out this june

[qazvick]

Hey all. I'm hauling her out this June for a bottom job.

I'd like to inspect my thru hulls while it's out. Also, I noticed that both of my sinks do not have any sort of sea cocks or proper venting. what would be better to do? Add a sea cock? Or add proper venting to the sink drainages?

Also, I'd like to drill a hole or two into the rudder to check and see how saturated it is. The surveyor told me there's a 2"x2" chunk of layer of fiberglass missing on it and that it seems like it may have water in it. I won't be ready to attack the rudder at this point but I'd like to see how bad It really is. once I drill a hole into the rudder what would be the appropriate way to close it back up?

Anything else I should inspect while it's out of the water? The cutlass will also be replaced.

Sinks on boats do NOT need vents like home plumbing does.

Yes, install proper seacocks to all hoses going thru the hull.

MAN do I love straight forward no nonsense answers I get on this forum. Thanks again.

It would also be a good time to inspect, and replace if needed, the log hoses and packing at both shaft and rudder.

I note you joined in May 2015. Welcome to the forum.

We got different Cherubini Hunter models, but I would expect that the thru-hull types might be the same. All the thru-hulls on my boat look to be original. Bronze with a plywood backing "plates" inside the hull. Not the method of more recent construction, but none of my thru-hulls are leaking. The plywoood is still good. No rot from constant wet. Each time I have hauled, I sand off some of the bottom paint and check that the bronze thru-hull fittings are still yellow (good) and not pink which indicates that the bronze has lost electrons and has become brittle and will most certainly fail at some point. A PO installed Marlon valves on all of the original thru-hulls. Like in the attached picture of my engine's raw water intake. I have felt comfortable with the PO's choice. You should install valves on the sink drain thru-hulls. And close them when not in use. Otherwise any failure of the drain plumbing can sink your boat.

Regarding the rudder, try a search using the site's search feature. You question has come up many times. Including a variant over the last month regarding cracks in a Cherubini Hunter 36 rudder. But in general, a wet rudder core is not specific to Cherubini Hunters. Info you find about other brands will assist.

Fixing the rudder is easier than you may think.
If you locate the wet spot, use a grinder and grind all that wet stuff out and a little past. Then you let it dry for a few days. After that you can use some epoxy with fiberglass "dust" mixed in. It turns into 'spackle' for lack of a better word. Just use a plastic spreader and fill it in. You will have to sand afterwards to get it smooth. Some would say barrier coat, but I'd just paint if you are running short on time.

Anyway if you don't do it this time, this winter should not be too difficult.
In terms of checking. Drill a hole in the bottom of the rudder, and one where you think the compromised glass is. If water comes out of the bottom hole, you have water in the rudder.
Use some epoxy with some filler to plug the holes back up.
If you have time and can get it clean & dry look into a 'penetrating epoxy' which you can use a syringe to fill through the hole. I would recommend the grinding technique though.
Thanks for posting, keep us updated!
