Companionway Sliding Hatch Removal

Hi all!
My neighbor/friend in the slip next to me has an older (appears to be late 70's, early 80's) Newport 30 with a companionway hatch that when it slides, produces a screech that would make any prisoner of war give up all his secrets. No joke. So, he being mechanically challenged, I am taking it upon myself to fix the situation for the good of all on our dock. :-) Problem is, I can't seem to see how to remove it. There are some sort of pin/bolts into the deck, but no heads to unscrew or an exit through the top of the deck. Could anyone give me an idea how to go about removing it? All the liveaboards on our dock, myself included, will be eternally grateful!

Has he tried cleaning the track first.
When I got my boat it had mud tubes from wasps on the track, the mud grit took a lot of cleaning to remove then I lubricated with sailcoat, no more screeching.

Re: Companionway Sliding Hatch Removal

Have you tried lubricating the slides? Maybe a shot of Teflon based spray will stop the interrogation on the dock.

Re: Companionway Sliding Hatch Removal

Not sure what kind of boat, so it could vary but there are probably pawls that flip down by gravity on the back of the hatch. Slide the hatch closed, then reach to the back (i.e., toward the front of the boat) of the hatch opening and feel underneath. You should feel the pawls. Flip them up with your fingers or long screwdriver while pulling the hatch aft (i.e., more closed) slowly. Go slow and be careful not to pinch our fingers.

Can't you just wax or SailKote the track?

Re: Companionway Sliding Hatch Removal

Haven't worked on one of these, did look at a few online pics of N30's for sale. Many builders of this vintage screwed the spray hood down from the outside but the screw heads would be obvious. I suspect you will need to remove part of the head liner to access the bottom of those pins/bolts and you will find nuts and washers there, or maybe a Chicago screw.

So, how are you going to stop the slider from screeching?

Pictures of the hatch and pins sure would be helpful here...

Re: Companionway Sliding Hatch Removal

My Cal 2-27 does the same thing. Part of the problem seems to be that the hatch on my boat is just a single piece of fiberglass, so it's so light that it can vibrate and act as its own sounding board as it slides. The hatch is sort of corrugated, so I've been thinking of adding some wood between the ridges, and/or add some thin strips of stainless to the "slides", to dampen some of the sound.

Here's a pic from another 2-27:

I had a Newport 33 and the companionway hatch had a bolt at the front(aft) side that acted as a retainer for the slide portion and the there were screws that held the actual coping in place. I have a excellent picture of it but can't seem to figure out how to attach it. I will try to pm it to you.

Re: Companionway Sliding Hatch Removal

There may be bungs in the wood rails that are hiding stop bolts, and the hatch ay actually slide forward to go past them and come off. If there are no bungs, and no stop bolts going through the wood at either end, it is possible that one of the wood rails will need to be unbolted to allow the hatch to come off sideways.

I'd sure try the "clean it with a dental pick and then Sailkote the tracks" approach first.

There are also teflon draw slides sold in hardware stores and online, they look like a strip of white tape with adhesive on one side. Clean the track, degrease, stick it down and then the hatch slides over THAT instead of the fiberglass, making it a little snugger and quieter at the same time.

Pins? Do you mean rivets?
