Post Subject: Aluminium replacement deck boards for cruiser stern narrowboat

Hi Tony, My laminated wooden deckboards are in need of replacement. It has been suggested to me that I could use "diamond chequered" aluminium plates as a durable replacement. Have you any experience or comments to make about the suitability of the idea? Regards Ray Fairwood

It is used for that purpose but I have three concerns. First of all will it be strong enough in the thickness you can afford to span the supports. On my boat it would have to span over 3 ft and I suspect at that span it might need to be well over 1/4 inch thick. Secondly where as wood tend to absorb engine noise the aluminium is likely to resonate. Finally it is likely to rub through the paint on the supports and if so it might corrode where it touches the bare steel. This will be a long term problem so may not be worth worrying about.

I have had some success using thin chequer plate on top of plywood .Make sure the edges are really well sealed and reseal them regularly, I also have a boat with a thick chequer plate on the rear deck which did 'resonate' a bit and needed some stickyback sound proofing.

Thanks Tony and Sooty1957 for your replies, I haven't finally made up my mind yet which way to go, but their doesn't seem to be any reason not to try the aluminium plate idea. Regards, Ray

I would consider bi metallic corrosion. You will need to make sure the metal rails and the aluminium plate do not touch, as the aluminium will oxidise.
