I like the school analogy.
I would associate ours with the school of hard knocks.
We learned that a 40 knot gust combined with an accidental jibe will rip a mainsail to shreds (we’re fortunate that’s all it broke), but we also learned that a new Pentax sail performs much much better than a 30 year old Dacron that looked more like a pool liner than a mainsail.
We learned that heeling isn’t so bad, as long as everything is stowed, but we also learned that they make a 12 volt blender to replace the 110V one my wife left out on the counter. Now we can have a margarita away from the dock.
We learned that cheap carabineers are a bad idea when it comes to securing fenders to the boat, but that new lifeline stanchion sure is pretty.
I’ve learned that water has exceptionally strong magnetic properties, as any tool left near the water will soon be in the water…Hell, I wanted an 18V cordless drill anyway.
