Kermit, in order to somewhat satisfy your curiosity, here follows an extract from 14th noon to 15th noon (all times are civil)
14th noon position by observation N31°29.7' W14°30.0'
14th 12-16 wind NbyE 2 Beaufort, course S23°30'W, distance 14.0 miles
16-20 NE 2 S20°45'W 18.0
20-24 NE 2 S61°15'W 21.0 during this watch Altair plus moon sights
15th 0-4 NE 2 S15°30'W 24.0 note 1)
4-8 NE 2 S15°30'W 26.0
8-12 NE 2 S49°W 22.0 note 2) and 3)
15th noon position by observation N29°23' W15°17.9, by dead reckoning N29°33.8' W15°22.8'; general course S21°30'W, general distance 121.6 miles
1) At 2h48m observed moon's meridian altitude LL 55°40'. Longitude at observation W14°50' of which latitude N30°20'
2) At 8h20m when chronometer showed 9h11m25s observed sun LL 38°8'30"; distance to noon 20 miles
3) Sun LL meridian altitude 74°31.0'
The reason the courses are given in degrees and minutes is that the steering (or standard ?) compass was marked in points (whole, half and quarter) and when corrected for deviation and variation the quadrant style was used. Leeway zero. All sails set except during 14th afternoon when some sail changing took place (changing to trade wind sails). I think they had a general cargo, including some dynamite as deck cargo, draft when leaving Hamburg 19'0" aft, 18'10" forward.
