    Kevin,

    I sailed with a few guys that did some trips on the SL-7's which were steam turbine. The Navy bought a few from Sealand and converted them too RO-RO for service in the first gulf war. They were fast at 30 plus kts. and required two time changes per day in some cases. Masters, Mates, and Pilots would ship out two 2nd mates to handle the navigation duties. Loran C was plotted on plotting sheets using tables and crossed with celestial LOP's for fixing. Those were the days :)

    Greg,
    I was referring to hours run.
    And my shooting technique is probably in need of practice and refinement.
    I think a good round of shots would probably be a lot more useful than a running fix.
    It would be intersting to know what the SEALAND SL-7 navigators did when they were cruising at 30 knots. They had LORAN A and C, OMEGA and DECCA but probably had 1 or 2 days in the Atlantic and 3 or 4 days in the Pacific of pure celestial nav.

    Best Rgds,
