Interesting question Ross
I consider my boating style (O'Day 272) pretty simple. I've been amused at the questions about recharging batteries for example, as, when at anchor overnight, I use the masthead anchor light, and for a few minutes at a time, the cabin lights. I turn them off with the same sense of urgency as our home lights now that BG&E are raising the utility rates. I have never (in three years) worried about recharging batteries with other than engine alternator, as I simply don't use that much power. Oil cabin light creates wonderful ambiance when at anchor in the evening, but to read we're generally using flashlights. I think I have about four or five on board. Original alcohol stove works fine as well. I have a handheld GPS and sometimes remember to bring along a portable radio to get NPR while sailing or at anchor. I have a VHF as well as a handheld VHF and almost always find myself using the handheld. No refrigeration - like Mike I use a portable cooler for keeping meat, cheese, and milk, etc. cool for several days. Much more efficient than the built in ice box which, next to the engine compartment, can lose its cool pretty quickly if I motor for any length of time. I use the onboard water tank for washing and flushing, and have a couple of collapsable 2 1/2 and 5 gallon gerri cans for potable water. Recently rehabbed the galley and head sink pumps with a little olive oil to lube the leathers. Worked surprisingly well. I do have (original to boat?) Cruising Designs roller furling headsail, which feels like great luxury. I replaced the drum unit before this season, and it works smoothly. Anchoring is completely manual and usually no problem in Chesapeake Bay mud. When the anchor gets stuck, a little power with no extra scope always breaks it free. Curious to hear how others respond.
