    For what it's worth, I for many years used HO 208 (Dreisenstok)as a matter of 
    preference, in navigating every size vessel. As with Ho 211 (Ageton) it's 
    small, convenient, one volume and universally applicable in the most 
    frequently navigated Latitudes and, I believe, more easily adaptable to use 
    of an assumed position. These tables, both 208 and 211, are convenient to use 
    on a very small chart table or even one's lap and, where several people may 
    be competing for the larger pubs, allows the user to work alone freely and 
    unhindered. In the final analysis, however, there are so many short tabular 
    methods available that it boils down to a matter of choice. based largely on
