    Um, the King owns the country. It is all his money, economy, lives of the citizens, all of it. The USA was founded on the principle of killing off the aristocracy. It came back of course: Trickle Down Economics really means Aristocracy.

    Minney's is amazing. I am looking forward to the re-opening.

    Solar to Shore Power inlet

    That is a significant point!!!! The inverter consumes 75 watts!!!! If I leave it on all the time, passively, then that is 75 x 24 = 1800 watt hours!! Holy smokes!

    Solar to Shore Power inlet

    Thanks for your insight, ISream: I may well follow your advice eventually. I have not yet bought anything, I may come to your side on this. The reason I am starting with this thought experiment is because charging the lithium batteries has been a pain. So I want to use the same charging approach that I finally have. At least I understand the strengths and weaknesses of the current configuration. The reason I might well change my mind about this, and follow your suggestion, includes all the reasons you mention. And because I may well rip out the current install, re-wire YET AGAIN, and use a single (or double) 48V battery for my high current loads (propulsion and inverting), and use the 4 x 12v LiFePO4 in parallel for the house low current house loads (mostly LEDs, refrigeration, and instruments). That will allow me to get rid of the buck converters I currently use.

    Oh. This also means no switch is required!

    Solar to Shore Power inlet

    Some more investigation ... including some time spent on the phone with technical support at Magnum. The Magnum MS PAE 4448 inverter/charger accepts 120V (such as normal 30amp shore power), or 240V (split phase, 180 degrees between the phases of 120V AC between red & neutral, and black & neutral), but not 208V (which is three phase, 120 degrees between phases). When using microinverters, the microinverters must output 240V split phase. The enphase IQ 7 does this, and works with Sunpower 170 watt semi flexible panels. The output of the microinverters is connected to the OUTPUT of the Magnum inverter. Weird, right? The way the Magnum controls the output power from the microinverters is interesting: the inverter alters the 60Hz frequency on the inverter output slightly: 60.6Hz turns off the microinverters completely. This is an international's standard for how microinverters are controlled. There is no separate signal anymore, its done by shifting the frequency of the AC **output** by the inverter.

    Solar to Shore Power inlet

    I am about to buy some solar panels for my all-electric Olson 40. This has been somewhat of a science experiment, and it has taken awhile until charging the LiFePO4 batteries using shore power has worked as expected. Rather than have yet another charging system, and working out the kinks in that technical duplication, I am thinking of using solar panels wired to micro-inverters (which use MPPT) to generate 240VAC, and wiring that split phase AC to the existing charger/inverter, a Magnum PAE 4448, to charge the 48v bank. I have investigated this, and it seems like it will work. The Magnum PAE charger/inverter is currently wired for 30A 120VAC shore power, but can be wired for 60A 240VAC as typical for house service from the utility, where each hot leg is out of phase by 90 degrees (hence, sometimes called 208VAC). So it appears I can keep the 110V 30A shore power going into the PAE, and also wire the AC output from the micro inverters to the PAE. And of course, a switch, so I only use shore power OR solar, not both at the same time. Has anyone tried something along these lines? Any lessons learned?

    Sngle handed head sail arrangement

    Mine is an Olson 40 with an Andrew designed 7' deep bulb keel. So about the same draft as original, but much lower center of gravity. Similar righting moment as several people on the rail, with no people on the rail. My jib or lapper is fully battened, with the lower batten going from the clew, perpendicular to the headstay. This means I can wing it out when nearly DDW without needing a whisker pole. It works better than I expected. But usually we tack downwind as that is more fun and safer (no gybe risk), even if not always faster.

    Sngle handed head sail arrangement

    I am finding the carbon fully battened lapper to be much more effective than I thought. On a broad reach from Catalina to LA Light, I nearly caught a well sailed Bene 367 with good sails and spinnaker, just using the main and lapper. The 367 left Catalina about 20 minutes before us, chute up. 0-10 knots of breeze over 20 nautical miles. We were closing on him in the Island wind, he gained on us when it almost shut off during the transition, and then we closed steadily once we were both in the same westerly breeze, passing them just inside the light. You really don't need that many headsails on a ULDB, if your headsails keeps their shape. Carbon gives that stable shape, and light weight so it flies well in ghosting conditions. Stable shape even as the wind increases dramatically, lift-to-drag is maintained. Stretchy sails get full, so drag increases: the direction of that total lift vector moves from nice forward driving force to a lot of heeling force.

    Even 8.5 meters LOA would be insane. For certain, 5.8 meter LOA is a death wish around the Great Capes.

    The Refit - Andrews 43

    We will also paint this year. We already did the decks before launching. Dennis suggested we wait until we stop bashing the topsides, so we did. Still never dinged the topsides, but it is the original 1983 gelcoat, and it is getting very thin.

    Everyone is buying boats...

    It is never as bad as it seems. All news outlets have always followed their creed: “If it bleeds, it leads!” Every single market crash in history has already been recovered from. Urbanization only increases, as it has over the past 12000 years, and probably for the past 3 million years: groups of people can do what individuals cannot. So I feel confident. It has always worked out very well for me on any time scale longer than a few months, for my entire long life.

    CS36, C&C 33-2, Ericson 35-3, Cal 33-2...

    The Abbott 36 looks sweet! Something very noticeable about my Olson 40, which is almost as narrow as an Abbott 36, is that narrow boats move MUCH more smoothly through a seaway than the more typical 3:1 length-to-beam ratio “typical” boats. The difference between a J or Catalina and mine, when going through a tugboat wake for example, is quite remarkable.

    Oh, duh. I see they do have a lifting keel. 7.5 foot draft.
