I bought a dc to dc adapter (link: http://www.buymac.com.au/product/magsafe...r-macbooks) and have used it on the boat for the last week. It does a good job of charging the battery and maintaining power. I actually burnt out the AC adapter that came with my mac book pro when I ran it using the boats inverter. Have since found out that when the electrics were changed over from US to Australian the inverter that was put in was a modified sine wave. Live and learn...
