Brought the new battery out to Nauti-Dog and installed it in it’s box. I purchased a West Marine Dual Purpose battery as the house battery for the electronics. While I was under the cockpit I measured all the wire lengths required for the second battery and switch. Also started the Yanmar for the first time in 10 days. It started fine and pumped plenty of water. Also did some general tidying up too. One of the other things I tried today was to find a way to transfer waypoints from the laptop to Raymarine MFD. Unfortunately I did have any success so I manually entered a few to start.
