Rust is accelerated because of exposure to oxygen. (Think of the Titanic still there in its low-oxygen environment.) Leaving the anchor under water should reduce the rust problem. Rust on an anchor set on the bottom some 20'' down is also much more difficult to see. The action of setting it may actually scrape off some of the rust as well. If your anchor is rusting from non-use, you could also paint it. I painted our (unused so far) spare anchor with Rustoleum and have had it stored below for five years now without any problems. Other solutions might be to have the anchor re-galvanized or (even prettier!) chromed. Stainless steel anchors can be prone to getting bent, and a bent anchor looks a lot worse than a rusty one, IMHO.
