Universal Plotting Sheet PDF and Sight Reduction Forms Pack

£6.99Price

Work a complete sight from sextant to fix on paper that guides you at every line.

  • Universal plotting sheet for any mid-latitude, with the longitude scale construction printed on the sheet

  • Step-by-step sight reduction forms for the sun, and for stars, planets and the moon with v, d and HP corrections, every sign convention and the Z to Zn rules where you need them

  • Meridian passage form for the classic noon latitude, and a Latitude by Polaris form with a built-in compass check

  • Compass error by azimuth form, from true azimuth to deviation

  • Sight log that keeps the whole passage, one line per sight

  • Compatible with the Nautical Almanac and NP 401, HO 229 or Pub 249 tables

  • A4 and US Letter editions of every sheet, unlimited personal printing

Eight working sheets cover the full celestial workflow: shoot the body, reduce the sight, plot the line of position, and prove your compass while you are at it. The forms follow the standard almanac plus tables method taught on OOW, Yachtmaster Ocean and USCG courses, so what you practise at the kitchen table is exactly what you do at the chart table.

Free blank sheets exist all over the internet. What you are buying here is the system: every correction signed, the rules printed at the point of use, the sheets designed together so the numbers flow from form to plotting sheet without a textbook open.
