So I finally accounted for the minimum tools I use during a CN Sun shot and wrote them down MOSTLY in order of use. Where applicable I included in (parentheses) alternate tools that would be just as useful. Of course some of these tables can be replaced by calculation, but if I could only choose one method I would choose water-proof paper tables.
Pencil
Paper
Watch
Timer
Seaman's astrolabe (Sextant)
Electronic calculator (Abacus, and slide rule)
Current Almanac Sun (Table 4)
Increment table
Chart
Pub 249 (calculator)
Table 5 (math alternative)
Dip table
IE data
Altitude correction table
My personal Proforma
Plot table
Plot sheet (or plain paper to create plot sheet)
Tape to secure plot sheet to board
Pencil sharpener
Protractor
45 degree triangle
30/60 triangle
12 inch ruler
Eraser
Dividers
Compass with pencil
How does your minimum equipment list stack up? Of course on the boat Id want a ships magnetic compass and hand compass, some kind of depth finder, chip log or equivalent, some kind of light, work space, and backup supplies. I think I would also want almanac tables for all bodies. If I had a lot of time at sea Id study the lunar method and start practicing.
