Evanston: some numbers
Evanston: some numbers
I used an online map tool to determine distances between various locations and an app to convert them to Nautical Miles, usually rounding up.
I checked some against my electronic charts and they seem to be accurate.
These are mostly straight line distances, sometimes crossing land. Actual sailing distances will be greater. But this is an acceptable basis for comparison and planning.
San Diego to Honolulu 2300
Cape Horn to Cape Town 3600
Auckland 4400
Honolulu 6500
San Diego 5900
Papeete 4300
Falkland Islands 400
Cape Town to Hobart 5500
Auckland 6400
Perth 4700
Hobart to Bay of Islands 1400
(actual sailing distance; not straight line)
Auckland to Honolulu 3900
San Diego 5700
Honolulu to 40ºS, 160ºW 3700
40ºS, 160ºW to Cape Horn 3700
7400
(this more accurately reflects true sailing
distance with prevailing winds)
