I thought I would update the group on the results of my search for marine-quality sliding door locksets for my 1" thick teak cabin doors on our '87 DeFever 41. The original Sea Bird units are made of steel parts in a zinc die-casting with only the locking cylinder made of brass... needless to say, they are very corroded and rusted. I could not find the Taiwan OEM but I did manage to source two new Sea Bird locksets for $US15 ea. Plus S&H from the original builder, Bluewater Yacht Builders Ltd. In Taipei, Taiwan. I plan to acquire these anyhow as a quick fix and back up. In searching for a proper marine lockset, I ran into a lot of dead-ends. The TWL list and DeFever Cruisers organizations had no sources and a number of replies asked for the results of my search. It may be instructive to briefly mention whom I did contact without success. The following suppliers were contacted by website search, e-mail and/or phone with little luck: West Marine, Boat/US, Merit Metals, Taco/DIY Marine, Perko, Mobella, Schlage, Weiser, Gas Springs, Freeman Marine, Stright-MacKay (NS), Mercers (NF), Vetus, HMP (Toronto), Hawboldt (NS-based custom SS and bronze casting) and Lee Valley Tools. I also contacted several boat builders and marine repair facilities without much luck; however, one of the boat builders led me to Brass Works and from there to Schwepper Marine Hardware. Schwepper appears to have a full line of boat-ship hardware including several versions of sliding door locksets. I should mention that Mobella (Sweden) appears to have a fine line of SS door locks for thicker doors; however, their only solution for my 1" door required a major retrofit. http://www.schwepper.com are represented in the US (Orange City, FL) by Brass Works, Inc at info@marinedoorandcabinethardware.com and in Canada by Fairwater Sales (Turmot Inc.) in St. Laurent, Quebec at tonyfox@turmot.com Schwepper has their hardware catalogs available in .PDF format for download. At this time, I am still in the process of acquiring the hardware (the 969 series) and if any of you are interested, I would be pleased to tell you of the results in a few months. Happy Holidays!
