The very first time, yes. Later on, I had bought one of these programmable calculators (in Basic, I still have the calculator) and had written my own spherical trigonometry nav programs.

This first time, I was the only person onbard with any navigation knowledge. It took me the better part of two days to master the beast - I mean, do a sighting while the boat is trying to throw you overboard, then fight seasickness and work out those mysterious tables.

It's a whole new feeling when you are out in the ocean, and you know where you are because you've been able to position yourself with some distant stars. Kind of part of the cosmos.
