Assuming you're referring to laser-ring gyros, I know they're fairly common on commercial aircraft these days - don't know about merchant ships, but maybe Jeremy can address that one. Probably still too expensive to be viable for yachts, but the same used to be said for the early days of GPS so hopefully the technology will eventually filter down to our level. -- GregR > I also used to do gyro checks by dock when firmly attached to a well > charted pier.
