    Norm - I may have missed it, but observing sun set and sunrise are
    opportunities to get a LOP without a sextant - all you need is a good
    watch, and an approximate DR.  A compass is helpful but not necessary.
    
    You can use your sextant for the observation but do not need to measure
    altitude (HS) - it is (obviously) zero.  Note that HO will be negative.
    
    Cheers!
    
    > Thanks all for your sage advice.  Can't wait for our trip to commence.
