Oh yes, and boats do require quite a bit of maintenance. I do most of mine myself and actually enjoy it usually, but it's not always on my schedule (although I try to be proactive, that helps).

One last thing: as a geek I really love fiddling with the boat systems. Having only two car-type batteries is not a lot, so I've been doing little things like replacing lights with LEDs (every boater should consider that IMHO for 1/8th draw and better longevity), changing how the charging system works, getting some solar going (in progress), etc. It's off the grid living!
