Concon is the closest thing to a yachting center near Valparaiso - I stopped there in 2012 for a haul out and some repairs on a circumnavigation. There was a travel lift and a marina / yacht club, and everyone was very welcoming, but pretty much jack-all in terms of marine trades / chandleries - was very glad my (now) wife brought down a suitcase full of parts and we pent 2.5 weeks raiding all the local hardware stores for anything vaguely marine-adjacent.Always thought it was Valparaiso, but that must have been more like paradise for the old sailors, the real Cape Horners...
