Essential Instruments?
I’m a “techno-junkie”, and I’ll always have all the “toys” I can afford - BUT, they are just toys. We don’t NEED anything beyond an accurate chart, compass /w correction card, & timepiece for most piloting/navigation.We need to know Time, Speed, Distance, & Direction. Given 2 of the first 3 + direction; we can plot a position, maintain a record of track, and calculate a course to steer.GPS is great, but best when you’re using your own saved waypoint information. For instance, Bimini is actually located a mile or so (if I recall correctly) from it’s charted position. I wouldn’t sail without one (‘cause I can afford it), but it’s (in no way) essential.Depth can provide useful information, but it’s not predictive, and often provides the most useful information just after you’ve otherwise acquired it (ie: I was in 6', but now am in 5' - on my 5'6" draft - bump, oops, look @ sounder, sh*t). Speed and/or Distance calculations are time-consuming, but I did it for years (on foggy Lk. Superior). After my compass & watch, Speed/Distance would be my next instrument. I might add that my wife, Maggie, is an excellent helmsman, whereas I’m not. Were I alone, or with a lesser helmsman, I might feel more need of speed instrumentation (that I could pay more attention to heading/course). Auto-Pilots give a lot of time back to their users, but (after all) I can steer myself. Mine is always “on”, but (like the other toys) it’s not essential. Wind Instruments provide interesting numbers, that don’t mean a thing until you’ve learned how to interpret them - by that time, your senses can provide the same information more quickly and intuitively. I know when to reef, even when I don’t know the numerical wind velocity.As I began, I love em all - but they are merely conveniences, assisting the otherwise competent master. I’ll take all the help & convenience I can get, but won’t let it’s absence deter me from my prudent enjoyment of sailing/cruising.I might also add, that if your skill-set does not allow you to "do without", you'd best limit your sailing to the most benign circumstances.OMOGord
