Its generally not considered “best practice” to change antifoul brands, but sometimes circumstance and availability requires change. We changed from International to Jotun without a problem.
Boat stuff
Upgrading the anchoring system
We were never really comfortable with our bruce anchor and now it has been relegated to the reserves bench. My research into anchors lead me two names and a cross Tasman contest, Rockner (NZ) vs Sarca (AUS).
Upgrading to lithium house batteries
Our house batteries, inverter/controller and solar panel controller had a complete melt down. Why this happened, we don’t know as we weren’t on the boat at the time. End result, we needed to replace the lot while in Darwin.
