    Re: GPS and uncloaking

    I agree with you Mr. Tait.
    
    I am a firm proponent of the sextant and magnetic compass but the one
    electronic gadget that I can't imagine being without is radar (and sonar). I
    can remember several trips where the fog was down to the carpet and the only
    way to spot huge icebergs was with our radar.  GPS only goes so far in terms
    of a safe passage.
    
    Having visited the Orkney Islands a few years ago I can only imagine the
    brutal conditions with which you folks must contend. I have to say I was
    really impressed with the boat designs. I wandered around the dock area one
    day and noticed a lot of small fishing vessels have adopted the canoe stern
    design. That says a lot about the local conditions.
    
    Had the pleasure of meeting a few of the search and rescue folks and even
    got a tour of their incredible rescue boat. I came away with the feeling
    that the mariners in northern Scotland are amongst the best in the world.
    
    cheers,
    
    Robert
