The sparkie at my previous marina (Bobbin Hd) came aboard annually and connected up to the bonding system and then dropped the test anode over the side and took readings. Everything was always perfect post the shaft brushes. Haven't had that done at Cabarita (there's no resident sparkie) but now you've reminded me, next time I see a contractor-sparkie at the marina (a couple seem to be regulars) I might get them to do the proper test, just to be safe. Certainly a visual inspection of the below-waterline metals all looked good this haul-out, but one never knows without actually do the proper micro-voltage test. (nb: I do have 2 x big aluminium 'maddox' anodes on the transom to which the bonding system ties back; they last about 24-30 months)
