         I would go one further and say for 125 years thousands of navigators successfully navigated from port to port with only one good 'noon sight' & 'time site' each day.
    And the reason they were so successful was they marked their position on a charts and were meticulous in their Dead Reckoning and log keeping.
    I bring this up because without fastidious Dead Reckoning & logging you are lost in between fix s. I teach boating safety with the CG Aux and it blows my mind
    to see people leaving the dock without a weather briefing, or paper charts, and every once in a while with out a gps either. I actually had a power boater from CT. pull up
    to my sailboat at the beginning of the season and had this exchange: "a what harbor is this?" "Huntington, where are you going?" "Oysterbay" "got a chart I'll show you"
    "no" "what does your gps say?" "don't have it on board" I'm a cfi and Master 50 ton and if I ever had an exchange like that the FAA or CG would put my credentials through
    a shredder! BTW: someone mentioned Sumner - I think his DR error for the 600 mile leg of the trip he 'discovered' LOP's on was 30 miles or 5% West of his actual position.
    So he might have made Smalls light regardless - just more apprehensively.
