I have a love/hate relationship with technology. I've made a pretty good living developing technology, and my mind definitely gravitates toward the high-tech solution to just about any issue.
But, I guess that I get my fill of technology when I am off of the boat. When I am on the boat, it isn't something I really want as a part of my experience. I sail, in part, to connect to an ancient tradition. It's hard to do that staring at a chartplotter.
That said, my new boat is packed with quite a bit of tech: chartplotter, wind speed/angle sensors, depth sounder, radar, satellite weather, hot/cold running water, a shower, an oven, AC inverter, remote control autopilot, windlass, and a few other gadgets I don't need. I have had the boat for 2 months and I still don't know everything I have. I don't eschew technology aboard so strongly that I would remove any of it. But, if it breaks down, I won't miss it and I won't replace it ... for the most part.
I guess, to answer the question, I would say that almost none of it actually increases my enjoyment of sailing. And, it could all break down tomorrow and I would still just go sailing, as before. Of the tech that I do have, about the only things I would spend any time/effort to maintain are:
- diesel heater (Having a heater means I can sail all year.)
- hot water (I wouldn't have installed it myself, but having a water heater is pretty nice.)
- VHF (Because ... safety.)
- electric lights, interior/exterior (It's good to see and be seen. And, we do sail at night.)
- stove and oven (Tea is mandatory and fresh-baked cookies are awesome.)
Notably absent from this list are all of the higher-tech items like the chartplotter, radar, and autopilot - the most high-tech items on the boat. Ironically, I use the auto-pilot a ton and the chartplotter is always on for a quick view of current speed and ETA. Like I said, it's a love/hate relationship.
I actually resent that my chartplotter tells me the wind speed and angle. I've sailed a lot of years to develop a sense of these things without being told by a computer. Every time I look at it, it makes me just a tiny bit stupider. And, I definitely can't afford that.
