door lock mechanism

I like to revert the door lock mechanism on my IG 36 back to the original inside the door lock system. The receiver portion of the lock is in the door jamb but the locking mechanism has been removed and filled with what ever. Does anyone know of a place that sells older locking mechanism for boats.

I bought a replacement Perko mechanism for our 30+ year old Defever last year. I can't remember where it came from but Google "Perko lock mechanism" and see what comes up. As I recall I had lots of choices of where to buy it and what I bought was an exact replacement.

I have no idea how the door lock mechanism on a GB compares to the ones used on an IG but we replaced the original, corroded, plated latch/deadbolt mechanisms on our main and aft cabin doors with 316 stainless copies from Victory.

We had previously replaced the badly corroded aft cabin door latch/deadbolt mechanism with an identical Perko unit but it began to corrode within a year. The Victory mechanisms (from China) have been on the boat now for at least 12 years and they look the same as the day we installed them new.

Don't know if these are available in your area but they are packaged under plastic on blue cards that say Victory all over them.

I wish the previous owner had left the old lock in the boat. Anything can be repaired or replaced if you have the original to copy. The rear hatch has a similar lock in it but the style won't work on the starboard slider. Hope somebody has some links, till than thanks for the offers on alternatives.

While we bought our Victory door latch/lock mechanisms from a marine supply house in Bellingham, here is the link to a company in Vancouver, BC that carries their hardware (plus a lot of other stuff). Rekord Marine is a distributor of quality marine products including our own Victory Products. On the home page select Products and then Cabin Hardware.

I have no clue if any of Victory's latch mechanisms match or fit an IG.

IG is getting a good run on TF today.
My aft entry sliding door lock is an old brass/bronze mortise lock,with a key I get hand cut to copy the one original I still have. Maybe remove the receiver part, record the dimensions on the door and visit a vintage building or locksmith shop.
Mine needs a little "lift" with the turning to open so I guess I have some wear inside. Also it can be double locked, ie a second turn of the key.I will check if it has a brand, but chances are it was made in Hong Kong.

My sliding door locks have a hook that engages a striker plate in the jamb. This is a fairly flimsy arrangement. I would really like to find something more robust that works on the same principal, or an explanation/picture of how I can use an alternative type.

Sunvale, here are pics of the lock. There is no inside pic, but inside is keyed too,and has a finger hole above the keyhole so you can lift the arm with the hooked end to open it. When you open from outside the turn of the key also requires a lifting movement. There is no "knob",inside or outside. When the door is fully open & restrained by the cabin hook, the lock hook is liable to tear clothing (and has), I suggest a more conventional lock without the hooked end, this may require a doorknob both sides. Feel free to ask anything else or request more pics.
Note my IG is a 1981 Europa, with no aft cabin.The door referred to is the aft saloon entry door from the cockpit.

Bruce and Andy, that is the locking mechanism I'm looking for. I have the one Shoalwaters shows and I don't much care for it. It's difficult to manage even though I tried to adjust it several time. Is there a manufacturers name or stamp on the lock?

Yes Andy, as per my post, there is a finger hole on the inside to lift the hooked lever. I hopefully take redelivery of my boat today after 6 weeks plus of deck repairing (goes back next week for Moorebank Marine Refrigeration, now servicing Pittwater Andy, to reconnect the cockpit freezer) and will look for a makers name on the lock.
Sunvale, you have seen the hook, even with the door wide open it protrudes slightly into the doorway;2 pairs of short pants with repaired tears prove its effect on clothing. Originality vs torn pants? There`s a tough question.
My boat is not quite as tatty as my pix look, there is sanding dust everywhere from the laying of new teak on top of new fibreglass.

Sunvale,

There are no manufacturing details on the lock. They were made in Hong Kong in the early 1980's so probably long gone. I don't particularly like the set up, as Bruce says the lock can catch you out, and those finger holes can be a real killer if your're not careful.Still if I come across anything down here i will PM you.

Bruce.
An exciting day, don't forget to post pictures. I may have given the wrong impression about my eutectic fridge in another post, she is now working very well. Moorebank did the fridge work on Sarawana for the PO.

Thanks for the information. If I might ask, what work have you done on the teak deck. I think that I have a slight leak port side mid ship when it rains for a sustained day. Going to pull up some teak and see if I can find the culprit.

There are easier ways to find the leaks. First, after a rain (or hosing down) look for the seams that are the last to dry. Good clue. Another way I've used is to seal up the boat as much as you can and pressurize it (or the suspected area) with a vacuum cleaner set to blow and spray soapy water. Doesn't take much pressure at all to make bubbles show up where the leaks. Use sidewalk chalk to mark the areas for repair.

Great advice Keith.

Land based equivalent testing is done with a device called an air door. Some utility companies perform air door testing of homes with these devices free of charge to qualifying customers. Reversing a shop vac would be plenty of air for testing a boat.

No brand on my door lock either. IG did some copying of GB,check if GB used a similar lock.
Much of my deck work appears on the "IG teak decks" thread. In short,all teak lifted, surface cleaned of Sika etc, defects repaired, a layer of new fibreglass, surface faired, on bow section another layer of f/g followed by non slip painted finish, on the rest new teak, essentially glued not screwed. And I was lucky,my IG has foam (not teak) sandwich deck substrate, but where there was wood there was rot.
I would not just start pulling up teak for a look. The caulking and the plugs are the aspects to approach first. Depending on deck condition you can recaulk, but if you have rot under in the deck sandwich and the teak is not adhering to the substrate caulking may not help, and even recaulking is not that easy.
The teak will likely fracture coming up,and only comes up after screws are removed or cut around, it will likely be laid on a sika bedding. Then you`ll be buying new teak to relay. I had one area which became "charged" after protracted rain and then leaked into the head at deck level.
Attempts to nip up the port stern gland failed, it now trickles, the boat has to be slipped after Christmas and the HWS and timber plate it sits on removed to access the stern gland. Great design feature Harvey! Fortunately both bilge pumps and switches are in good order. The joys of boating.

My leak is very minor, and the deck is solid wood, glass on top and than the teak. I will take it up and look for obvious cracks and do the vacuum test after the teak is up. Is the teak glued down and screwed to the deck?

Teak is a very brittle wood, particularly as it gets older. Bruce is correct in that trying to pull up the teak planks may very well fracture them. The sealant/bedding under the planks used by most builders like GB, IG, etc. has significant adhesive properties, so removing the screws does not mean the planks will come off nicely. You'll have to pry them off and that is when they fracture or break.

The deck screws are usually the source of leaks into the boat. If water gets down under the planks to lie between the planks and the upper surface of the subdeck, it can migrate down into the deck core and even into the boat itself alongside the plank screws, which often penetrate all the way through the subdeck. The two ways water can get under the plankes is thorugh separated deck seams (most common) and down past deck screws that have lost the teak plug covering them, or the plug is no longer watetight.

Keep in mind that the location of the leak inside the boat may be quite aways away from the spot where the water is getting down through the deck. Water has a nasty habit of migrating, so if the leak is coming out of a headliner or some other decorative fabric that was installed to hide the coarse underside of the deck you may have to remove the headliner or fabric to trace the path of the water back to where it is actually coming through the deck.

Sunvale,You have the advantage of seeing the issue with your deck, but I`ve been at the yard every day for 7 weeks checking progress on my deck. After the teak was levered up with a pinch bar, chisels and then a sander,were used to remove the black sika like goop the teak adhered to. That took days.
The actual substrate deck under the (near) decorative teak strips almost certainly consists of a top layer of fibreglass, the sandwiched layer of teak blocks, and a bottom layer of fibreglass. (In my case,the only known one, foam material replaced teak blocks). Those myriad screws can conduct water to the substrate, failed caulk can conduct water to the base of the teak strips. That is why a recaulk and or replacing failing plugs may help. The teak strips abrade, reducing thickness, reducing the ability to replace and retain plugs over screws.
You could post pics of your deck,especially the area you suspect.
Marin did a successful full recaulk, AndyG did a full deck reno,(all done by professionals except Andy removed his old teak, did substrate repairs and prep), so we should be able to give some input. I worry if you start pulling teak up you could get into trouble,but I`ve not seen your deck and can`t know your carpentry skills
