Here is one fix.

Search here for "sliding hatch" Or "companionway" and get lots more.

Just think of it as an early warning entry horn!

Be cautious that it might mean more than simply a sliding/rubbing issue and it could be caused by a screw or the seahood interfering with and damaging the companionway hatch.

Ugh, I found that out the hard way.  My boat formerly had a dodger but didn't come with the actual canvas.  Last spring I noticed some of the attachment posts were loose so I tightened them down.  Turns out they were intentionally loose because the screw point is too long and chewed up the gelcoat on my hatch after I tightened it.

Good grief!

Ya'd think the intelligent thing woulda been to either grind down the screw points (as the factory did on mine that hold trim on one side of a teak bulkhead so they don't poke thru) or put a trim washer under the head —- versus leaving loose fittings.

Some things yah find simply make your head rattle.

I used an adhesive uhmw tape that someone on here recommended.  These usually have pressure sensitive adhesive, so it is critical to prep and then firmly press the tape.  I removed the wood rails and sea hood to allow good access to the slide area.  After surface prep and laying the tape, I used a j roller to apply a lot of force to the tape to get good adhesion.  After 5 years, there does not appear to be any adhesion loss where I can see the tape.

My first season with Shamrock I did the same.  Remove seahood, clean, install uhmw tape, replace seahood.  Was a simple but time consuming job.  That was 15+ seasons ago and still works great although the uhmw tape is starting to wear out.

Guy : I installed the same tap by putting it on a aluminum strip.  Then I inserted the strip under the overhead hatch on each side. I drilled a small hole in the aluminum on the cockpit end and screwed it in place!! No need to remove teak etc.

All is quiet now.  A few thoughts
