I certainly do more land-based observations than on-the-water. Not by choice! It is interesting to get a feel for best-condition results and compare them to on-the-water results when available. Also keeps the sextant and reduction skills sharp. While I know the way from my home to my mother's home by heart after 41 years, I always use my GPS so that I know the unit is still functioning and what accuracy I can expect under varying conditions, as well as being able to use it without a second thought when spring comes around again. I would imagine musicians practice alone and with their group for those few hours on stage. And their stage isn't moving. Given that almost any task on small craft takes double the effort compared to on land, it sure helps to have the process down pat before you step on board. > > Essentially they are doing what land surveyors did, albeit using tools > evolved for nav from boats. Can't argue with that, but the goal is proficiency on the water for navigational purposes with a sextant, or for the sheer joy and independence of the process, not staking out a subdivision.A famed hockey player, Wayne Gretzky said, "It's not as important to know where the puck is now as to know where it will be." I imagine a surveyor is more interested in how to lay out the ice rink and place the goal net. Where the puck is or will be is of little interest.
