Many... of you have asked me about this lock. The original Beneteau lock is out of production, and IF you can get one of the people to scan the warehouse, it will cost in excess of $300.
As you will see in the top left picture, the Perko lock is considerably larger than the original. Notice the exposed screw holes.

To locate your replacement lock, take a piece of plywood approximately 6"x 6"x 1/2" and screw it to the door on the inside over the hole. Insert the lever into the overhead slot in the sliding hatch. (Just the lever, removed from the lock). Mark the center hole location onto the plywood. That is the center hole of the bottom of the lever.

Drill a small hole through that mark and you now have an external location for the center of your new lock. Using a hole-saw that is the correct size for your lock, insert the center drill bit into the 1/2" plywood from outside and drill until you touch the plywood. You should now be able to easily finish your installation.

Perko locks such as this, are available on ebay, West Marine, Defender, or almost any boat supply shop.

Most of the cabin is covered with a factory insulated vinyl, like most Beneteau's. The V-berth had been replaced with a homemade attempt to duplicate the original. As you can see from the before photo, it did not.

I tore it out, sealed all of the exposed glass, and installed contoured bamboo rails to provide a surface to screw into without damaging the fiberglass. I bonded them to the ceiling with 3m-5200.

After adding foil bubble insulation, I screwed the new ceiling in and started creating a hatch extension from solid cherry and wenge. I reinstalled the black-walnut from the original ceiling to the bulkhead and even created a removable piece to access the wiring block, at the base of the mast.

I have a 1985 Beneteau idylle 10.50.
Many of the other Beneteaus use the same lock.
I need to replace this lock on the companionway door.
I found it in the BeneteauUSA site, out of stock, and $195.20 Ouch!
I believe it's made by Perko. It's 2 5/8" x 2 1/4" x 5/8"
The Beneteau order number is 082551
The tumbler has a number 469 on it.
My boat... as you can see from this blog...... has a thick lexan hatch that slides over the main cabin. This dead bolt feeds up into the hatch to be secure. There are many similar locks but the deadbolts are thin & weak.

"ANY SUGGESTIONS?"

email me........ captbanyan@cfl.rr.com put the word Beneteau in the description so I don't delete it.

NOTICE!
A similar lock was about $300 from Beneteau and had to located by phone. I found a black plastic (with hard metal hardware) lock on eBay for $40 that works perfect with the heavy Plexiglas hatch. Thanks to those of you who sent me information.

After a few months on the Hard, The boat has a complete new bottom, new colors, and a new name.

The origional Curtains in this boat looked like someone sacrificed the back of their blue jeans, and screwed them to the headliner. They swung to & fro even while at the dock, and did not keep the incesant Florida heat out of the cabin. I leave the Air on all the time while at the dock, and it seemed to run too much. The issue with the previous owner and myself, was that the verticle liner between the Port lights was thin, and an effort to install hangers for the top & bottom rail of curtains would either not hold or eventually damage the liner. Finally a solid solution......! I shaped the wood (Sapele), to the contours of the boat cabin, cut a 1" Channel up the center, and routed a decorative edege on the 6 pieces. I installed 1" alum angle stock into each hanger and secured with stainless bolts. The exposed leg of the alum slid behind the interior Port light trim and tightened back down solid. I wanted heavy brass rod for the curtain rods until I searched and found the only comparable material was Stair tread carpet rods. "Way to expensive"! Off to Ace Hardware,,,, Fiberglass tomato steaks were really strong and only $4.00 each. I could get them all from 4 pcs. Next I found plumbing fittings that snugly fit over the ends. On the visable ends I screwed the fittings from the interior to the Sapele,, (All hidden), and on the other end I screwed from the outside with stainless into the fitting with the excess screw going inside the rod.

Hurricane Irene just passed us and is headed up the East coast. Can't say I was disappointed, but we have had worse thunder storms here.

In preparation, I removed the main and everything that could have blown off. I tied the bimini back, tied all the winch covers in place, tightened up the Jib, doubled the dock lines, closed all the thru hulls, tied the sheets to the mast, put out all additional fenders, and did a quick check of my Boat US Insurance.
I was on standby to add some old tires to the docks if she stayed class 3. She beat up the Bahamas and only gave us the edge. "Thank you, Irene"!
