No, but hardwood of such small dimension wouldn’t last very long. Why not use Aluminium? Porter and Hartley use it on their new boats. But don’t get it from a chandler or boat builder, check your local hardware shop or DIY centre first. Any Alu strip that is 12 mm wide will do just fine, square or half round or something in between. Just make sure it is stiff enough (thick enough) so you don’t need to double the number of screws to prevent it from bending away from the hull.
