It’s the three dimensions into two, conundrum…inadequately solved by projections. Crossing from Auckland to Melbourne a few years ago we calculated we would have saved 24 miles by following a great circle route rather than a fixed course. That’s four hours over an eight day journey.

A yacht may elect to race using celestial navigation. If a yacht elects to be celestially navigated, she shall have her elapsed time reduced by 3%.

We memorize the rising and setting points of stars and use those to orient ourselves in our physical space so that we can navigate from place to place. I used to think that we would go to things. But that island out there was always there and all you’re doing in your place is you’re making it come to you.
