I haven't read this issue yet (probably will arrive with ON mag next week), but I am wary of blanket statements that ignore some fundamentals.
Is tinned wire critical in low-load applications in dry boats? No, not necessarily.
Will untinned wire and the usual crimping suffice in many cases? Probably, given that many wires on many "good old boats" are original.
Is replacing with Halekai's techniques those wires that fail or those wires that are "mission critical" (like bilge pumps, battery cables, nav lights) prudent and seamanlike?
