I don't know if I am using the right terminology here (I am not even sure what to call it in Swedish) but the teak ledge on the port side of the companionway hatch has cracked and a big chunk has come off.



I have made trial ledge from an ordinary plank of wood in order to "rehearse" before the very expensive teak plank I have ordered is delivered and it seems I will be able to make new ledges and replace the old ones. (I didn't bother to make the trial one the full length.)



I will also have to replace the white nylon strip that the hatch rests on but fails to find a store to buy it from, or even know what to ask for. I am turning to knowledgeable forum members to see if anyone can point me in the right direction?

Hi,
I think the material is POM (Polyoxymethyleen) I only know a company in the Netherland who sell this in small peaces. https://www.perlaplast-kunststofshop.nl/technische-kunststoffen

Thanks a lot for that information! I helped me a lot in finding a company in my country that could deliver the material to me. Another name for POM is apparently delrin, which I am familiar with from the rudder bearings on my boat. It seems to be a good material for the acrylic hatch to glide on but I am being warned that it is not UV resistant. Maybe that's why it has become so brittle that it has come apart in several sections over that last few years or so? I will give it another chance if I don't find there is a better choice of material very soon.

I have removed the hatch garage and will order the POM trims tomorrow if I don't miraculasly come up with another and better material before then.

PS. The picture was taken after I had cleaned fifteen year's worth of dirt.

Johan,

you can change the material to UHMW PE ( ultra high molecular weight Polyethylene ) either in white or black. These strips could be sourced from any company selling plastic sheet, try companies which fabricate lab equipment. Search in your area for plastic fabricators or lab equipment, you might also ask at the KTH or any other university with a chemical reasearch department who suppllies them.
( you can ask also for HMW PE, sometimes they leave the "H" ).
Finally you can also try and find Teflon  (PTFE) strips

I found a company that, after I had used all my social skills, were willing to sell a sheet of Polyethylene to me. They were only directed towards businesses so a random sailor was not too exciting to them. I will get it tomorrow if everything goes well.

I have filled all the holes from previous solar panels on the hatch garage and temporily fixed the teak ledges (I still don't know if that is the correct word). I will change how the sliding hatch is prevented to go to far when pulled so that it can actually be removed easily whenever I want to do some cleaning etc.

So this is work in progress.

Johan

A friend with saw helped me to cut two 16mm wide strips from the 1x2m Polyethene sheet I got. (I have a lot of spare material if anyone needs it.) Fitted in place, they proved to work like a charm. The fact that they are black will supposedly mean that they are more UV resistant.

I am not a handy person so it is all a bit scary but once again it is proved that this forum is great for useful advice. Without it I would not have sourced the right material to use.

I will soon be able to put everything back in place and then my biggest problem will be that I used the word "ledges" as the subject line for this thread as it can not be edited. Maybe I should have used the word "strips" instead? Would "replacing companionway hatch strips" make more sense for a subject line?

I am happy to announce that the companionway on my boat is now fully renovated. I have replaced the broken teak strips, mounted new glide strips for the acrylic hatch to rest on and I have put gelcoast filler in all the holes from screws holding previous solar panels on the hatch garage. I have buffed the hatch garage and glued the new solar panel with Sikaflex. And I have settled for the word "strips". I will not use the word "ledges" in this context again.

I think this part of my boat looks brand new.

Are the teak guides just screwed into the deck or through bolted?  I have the same problem, and will have to make a similar repair this summer.

They are screwed with self-tapping screws.
