What was all that about plate copper sheathing?
Plate copper provides great mechanical protection for grounding, and non-toxic anti-fouling. It is initially expensive (at this writing, it’s running about $5.25/lb), but pays for itself quickly in haul-out avoidance (haul-out, yard fees, paint, brushes and such, treats = $$). It dissipates a lightning strike when bonded to your protection system. It’s high on the galvanic scale, so you need fear no “hot” neighbor. If your motor lifts out, you are mono-galvanic (copper and bronze) below the waterline, so no zincs. It’s heavy, so you’ll make up some of the cost on ballast savings. Nail, screw or glue it on (be sure to test your glue on copper, first) and cover the chines with bronze angle. Another, cheaper option (way second best, but don’t stay ashore waiting for copper prices to drop!) is to add elemental copper powder to epoxy, and coat the hull below the waterline. A light sanding exposes copper, which lasts a good long while. When spent, sand again. Mix it yourself to save $$ over
