I need to decide on the teak thickness of the cockpit deck flooring in my 36'' steel cutter. I realize that thickness will increase the cost, but I want the project to be done right.

I believe the deck should be at least 3/8" thick and currently I am considering 1/2". But since I don''t have any experience with teak decking I wanted to get some feedback from others with experience.

Thanks in advance for your input.

The thickness of a teak deck used to be determined by how big the screws holding it down were, plus enough for the bung to hide the screwhead. If the material was too thin, the screws wouldn''t hold it down properly, or the bungs would tend to pop out. This used to mean decks an inch or so thick. Modern glues have made it possible to glue teak down and NOT screw it at all. This is a good thing, since the screwholes eventually start to leak and then cause problems in the substrate that the teak is screwed to. If you''re just gluing it down, figure it might wear down every year or so, especially in a high traffic area like the cockpit. Half-inch stock might give you about 15 years of use. (That''s a guess - you may want to look at various teak decks of different ages to see how much they thin out in sun/rain/wind conditions where you are.) That''s why people often put teak grating on the cockpit sole, without gluing it down. It''s easier to replace, cheaper, and lighter.

Thanks Paul...

My plan is to NOT use screws of any kind, even if that means I have to reapply adhesive again later. I just spent $8,000 cutting out and welding in a new cockpit sole because of rusting caused by among other things screw holes.

I''ve heard that some yards and builders are using some kind of "vacuum" application for teak decking. Does anyone know anything about this process?
