I can't say whether or not smart rails are the way to go, but they are on a portion of the hull that is lible to get hit at one time or another. Teak will probably take more punishment. As to a source, a Shipwright or a good woodworker with access to a steaming/bending setup should be able to help you out. Shouldn't be hard, just a little cumbersome and a little pricey. What's teak, about 30./brd.ft., but I haven't checked it lately. It'd probably work out to 20-22 ft. of 12 qrt. x 3" or 10ft of 12 qtr x 6. You might be able to mill out of 8 qtr. stock and bevel both edges.
