How much are you looking to spend? If you really want to reproduce the same as whats already on the boat, I can bang the design out for you with my 3D CAD software. You can then take the 3D CAD model to a local machine shop that has CNC capability and have them cut it out of any material you want, you could also upload the 3D CAD model to
www.emachineshop.com and they will cut it for you also. The cutting may be expensive because of the setup time for one part.
IMO, this may be a good time to change the look and buy new vents from someone like
www.eddiemarine.com, ww.danamarineproducts.com,
www.livorsi.com, etc.
