    It occurs to me what these guys really needed was oar locks and a pair of
    appropriate oars.   Adding a 1kt - 1.5kt east or west vector to their course
    made good wouldn't have been the most elegant solution, but in both
    cases likely would have gotten them within site of land with a few days
    work.
    
    A sextant and tables could certainly provide a moral boost by confirming
    each days gradual progress, as well as potentially alerting the adrift person
    to an unexpected eddy in the ocean currents that might by accident be
    running directly counter to the added oar provided vector.
    
    So my feeling is that the sextant and accessories necessary to plot
    position without electrical power stay on the boat; a manual PUR
    desalinization pump would probably be a better choice for liferaft dollars.
