    Older well known IOR Boats

    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.

    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?

    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.

    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.

    I think it is silly to have a bow like that today. A fuller bow which means the knuckle is well above the waterline is proven faster in all fleets: from skiffs and planing dinghies, reaching back to FDs and 5o5 but certainly including Aussie 18s and 49ers, and of course so undeniably demonstrated by the mini 650 class and Class 40. Such bows do not need to be ugly. Sure, the recent examples are not just ugly, but ugly. However, the 5o5 is one of the prettiest boats on the bay. That 5o5 bow is beautiful and very, very fast upwind and down. I think it is silly to have a bolt on short sprit as shown. Short is stupid, I mean retarded. There is no excuse. Bolt on is also a dumb, dumb choice. A bolt on sprit where the sideways load is carried by the laminations on the sides of that sprit and the bow, is HEAVY and weak. The sprit should be like on a Mini 650: easily stowed, with side stays and bobstay, with vertical support (just the weight of the sprit) carried by a line(s) to the top of the bow pulpit. A Min 650 style sprit is dramatically cheaper and lighter, and can then be of an appropriate length, something like 12 to 15 feet. If you want to plane, you need the bow lift that comes from a long sprit. And of course, the longer the sprit, the faster and more fun. And cheaper!!!! And lighter!!! I am glad it has a single rudder. Double rudders suck so severely. It does not seem to have a lifting keel, so the keel and draft makes a lot of sense. Personally, I would keep the keel simple, as is. But to ease trailering, and to make the boat more widely useful on lakes, the Gulf Coast, the East Coast, a lifting keel can have several big advantages. Structurally more efficient: 1) A win for reducing materials and therefore cost; 2) A win for safety, as impact loads get spread throughout the entire structure. With ramp or small hoist launches especially at lakes, groundings will be common; 3) A win for market, in that the boat might be 12' deep keel down in the Pacific, 7' keel down along the East Coast, and 5' keel down in lakes. Maybe make the bulb interchangeable to three different length foils.

    Santa Cruz 27 Plans/Lines/Drawings?

    The worst thing about SC27 is the cockpit. I always wished mine had a cockpit like in this drawing! The second worst thing was the access to the outboard. The third was the lack of a way to get back aboard that does not require the person in the water to be quite strong and flexible. I don't think it will be necessary to shorten the coachroof nor alter the interior. Just cut away all the existing winch islands aft, and replace with that style cockpit, including the open transom. Will make the interior a lot better too, with sufficient space to get into those pipe berths aft. That style deck/cockpit will stiffen the boat too. I would make a deck level thwart to hold the top of the rudder, and to provide necessary stiffness for the aft quarters. The full transom is very important to structure as is. I think it will be easy to step over the thwart to access the outboard, and will give much needed hand hold for brining a person back onboard.

    WTF did they do to this J/125!?

    The fun thing about taking an ex-race boat and making it a cruiser is that you can make choices to make the boat even faster. Ignoring rating factors is a very good thing to do. Fast is Fun!
  20. I explicitly measured the headsail so it does not hit the mast, ever, to avoid beating it on the mast. Note that if one is trying to generate the most lift and lowest drag for a given amount of sail cloth (aka money $$$), instead of trying to have the most sailcloth aloft that a rule allows (aka sending the maximum $$$ to your sailmaker), then you want the leech FORWARD of the mast. The optimum location for the jib leech is at the lowest pressure point of the mainsail, which is forward of the mast (or else you would not sail forward upwind). Since my boat is about performance, rather than rating rule or enriching sailmakers, my jib will not take a beating from the mast.
  21. I think the sail works well in light air. Batten tension on tapered battens does seem to help maintain shape when it glasses off.

    Dimension Polyant Aramid Sport

    Remember that Aramid has FOUR problems not just one: 1) UV sensitivity, as already mentioned. 2) Absorbs water aggressively. This is why Kevlar hulls were such a horribly bad idea. 3) Aramid shrinks after being under load. This damages the shape and structure (attachment of filaments to skins). GPL sails last forever perhaps due to this giant advantage of carbon over aramid. 4) Aramid is much heavier sail, compared to carbon. Much heavier. So I went with GPL lite skin. Price difference was insignificant in the grand scheme of things, much lighter and therefore easier to handle sails, perfect shape, and they last much longer, based on actual experience and not brochure claims.

    what's wrong with it?

    I was hot for this boat about 3 years ago. My intent was "cruising retiree couple" and that intent is impossible. It really is much too big and powerful for that use. It has been upgraded since then, so even faster now. But is now even less appropriate for a retirement cruiser for a couple of (obviously old) retirees. Of course, if I was into the group sex scene instead of monogamy, and was single instead of very happily married, it might well work fine!! Plenty of berths, that is for sure, and about the right amount of privacy for orgies: none!

    what is it?

    It is interesting to watch to (slow) progress being made over the past year or so. The new double spreader mast with uppers out to new chainplates on the rail is an interesting alteration.

    Improbable

    On our first cross country trip, left Los Angeles in July, to Maine, Florida, returned just before Christmas. We got hit by Hurricane Sandy when we were in Long Beach NY. The entire island was underwater. Out truck we parked on a bridge, so it was one of the very few vehicles not destroyed. But I put all out stuff in a garage, which collapsed, letting everything be soaked in the toxic water. We spent a week trying to clean stuff, but ended up having to literally back the truck up to a dump and push everything into the dump. But by this time, we had been on the road for July, August, September, and October. So we knew what we actually needed. When we left LA, we took everything we could imagine we would use, but we just replaced what we actually DID use. Less than $500 for everything, including clothes. We don't live like homeless, we don't use plastic or paper anything. Tablecloths, candles, glass, china, silver, two chairs, folding table, custom pillow top mattress (that is inside the cab of the truck, so it was not destroyed) with high thread count linens, feather pillows, down comforter, etc. Shovel instead of a head, this aint no typical RV, we generally camp in the wilderness, quiet, stars.
