Silent Partner modifications

Sorry, no pics today.

I'm living on the Hans Christian...in southern Louisiania...on the hook (at anchor). This means no utilities, particularly shorepower. I use an inverter to run my laptop and occasional other small items when absolutely necessary (power tools, shop vac, very rarely microwave). The only air conditioning on board, or actually that used to be onboard, was an old and not particularly effecient unit. Most all AC units run on 110vac. This is primarily because they draw a lot of power. Except for electric water heaters (or those unlucky souls who tote around minuature electric washer/driers for their clothing) AC consumes far more power than any other appliance. The one exception is the "DC Breeze" unit built by Glacier Air. They also build excellent refridgeration/freezer units. I currently have little money, and so do not have the 12v DC Breeze. When I'm working at the boatyard in the heat during the day, and eating and sleeping without AC, it's not all that bad. You sweat sometimes, but adjust mostly except for those couple nights a month that are especially warm. I have a few 12v fans that help significantly, though they are a little noisy and consume some power. Eventually I want to replace them with the Hella two speed units which are extremely power friendly and quiet. During the school year when I'm stuck in air conditioned classrooms all day, and commute with the ac on in the truck, sleeping without ac becomes less comfortable. Even a little to drop the temperature down to 80 or even 85 and pull 10 or 20% of the humidity out would be great. Eventually I want to add a DC Breeze unit. I'll set it up so it is possible to cool the salon down a little, but it's primary task will be cooling the pullman berth only. The smaller space the less power it takes to keep it cool. And rather than running the engine an hour or two every single evening I really want to add some solar panels. Actually I'd like to build a fiberglass hard top instead of a canvas bimini, and mount the solar modules on top. This would not only cover my usage for lighting, laptop, fans, propane solenoid, and stereo, but actually let me run the refridgeration modestly (having a well insulated icebox and a new 12v fridge unit that was installed just before I aquired the boat helps save power also), and even run the AC sparingly without ever having to run the engine to charge batteries during the summer. In winter the panels won't put out as many amphours in a day, but cooler temps mean less power needed for food coolings, and no need to run the AC. With the currently decent effeciency of12.5% solar panel modules I should be able to get 300 amphours daily in the summer without trouble. Part of this is also because new solar charge controllers are very advanced. Several units now use a form of DC-DC converter. Instead of requiring an array voltage exactly matching that needed to charge the batteries, and resisting and wasting the rest, they take in whatever voltage and amperage, or maximum wattage, the panels put out. This can be anything from 12v to 48v typically. They then convert the voltage to that which is desired to charge the batteries, so the wattage is maintained and maximum possible amperage delievered to the batteries. This is also convenient because the solar modules used don't have to match the battery bank voltage. Sometimes it is cheaper to get 24v nominal panels now because they are often stacked for larger house and landbased systems. The wattage can also be the same but higher voltages with lower amperages mean smaller wires are needed (cost and weight savings). I personally like the Outback brand of equipment. They offer true sinewave inverters/chargers (best for electronics and laptops) and effecient solar charge controllers. They are interfaceable and programmable which is a nice feature. They also feature battery temperature sensing to protect the $500 of batteries the entire boat's system relies on. The central controller unit also monitors charge amperage and total amphours so it's easy to monitor if I'm drawing off more than the panels are replentishing.

Wind generators are also a great invention. I happen to have an old WindBugger which works just fine...when there's wind. Problem is most the time there isn't enough wind around the Tchefuncte river to spin it at all, let alone fast enough to generate useable power. In the worst part of the summer there typically isn't even the slightest breeze (except for hurricanes, which aren't the best time to leave a wind gen out there to shed alumimum blades through the deck). They're nice, but just not practical for sitting on anchor most the time in Southern Louisiania. There also ins't much if any current so I can't use a water generator. This area is basically a windless, currentless tideless, elevationless, humid, sunfilled hole...perfect for solar.

I could also use a diesel generator I suppose. On a larger boat or poweryacht that is certainly be a viable and popular option. I really lack the space for a diesel generator, even a compact 3kW unit. Actually I can buy the solar panels and charge controller to keep up with my usage for cheaper than a generator. And then a generator requires maintenance, parts, and fuel $ to run. It also generates noise besides electricity. Now I could use the heat output to heat potable water, but I can add solar water heating pipes and do the same during the summer without buying any diesel. And it's silent.

Before any of this I have some general wiring to clean up onboard. I'm also swapping my main battery bank and hot water tank. Currently the batteries are in the engine room (where it's hot and full of viberations) and the hot water tank is under the dinette seating where I'd rather it be cooler and where viberations are limited. The swap will put the tank near the engine, shortening the hose runs between engine and tank for the water heating exchanger. The main batteries will be more centrally located in the boat. This puts them closest to the main distribution panel as possible which lowers losses in wiring and reduces the cost of the new wires. It also moves them closer to the windlass and future locations of the AC unit and Electrasan sewage treatment processor. This again reduces power losses in wiring and less wire is cheaper than more wire. With the batteries under the dinette I'll be more likely to check their electrolyte levels more frequently and add distilled water than when they were wedged in the far corner of the engine room under the cockpit. This whole change also means relocating the pressurized fresh water pump. Not difficult since I'll slowly replace all the vintage 1980 copper plumbing with pexpipe anyway and routing wiring isn't a big deal. Only thing is I'll be without water or power initially. Then I'll still be without water for probably a day or two. No big deal really, so long as I get it done before I lose access to the shower at work in november and begin showering onboard full time.

Speaking of showering, the shower is in the forepeak and the hot water tank will be in the aft end. Running the shower waiting for the hot water to arrive can waste gallons. At some point I'd like to install a recirculation line an valve and a fast acting temperature gage. That way the cold water can be returned to the fresh water tanks. A temperature valve would make it easy to know when to shut the valve and get in the shower without wasting any of that preciously heated water.

Now in the winter there's less light and the sun isn't as intense, so I wont' get as many amphours from the solar array. But then I also won't be using the AC. I'll burn the lights more. However, I'm finding inexpensive sources for Luxeon LED's to relight the entire cabin. Using them I'll hardly consume any amps lighting the cabin. It actually does get cold here in the winter. Temperatures near, even just below, freezing at night for months and not all that warm during the day even though the sun is around. Staying away from shore power and diesel generators I'd still like to not freeze all winter. Last year I did okay heating the smaller boat with oil lamps and layering on cloths. I also typically studied at teh lab at school and pretty much used the boat for eating and sleeping. This winter I'd really like to keep the cabin more inviting with a diesel heater. The Hans used to have one, actually it was removed just before I got ahold of her. The closed off hole for the stovepipe and charlie noble hadn't even been fully faired in yet. If I can afford one it's the most economical and carefree way to me to heat. I could use propane, but it's explosively dangerous and I hate filling up propane bottles. I'd rather draw a daily quart or two of fuel off the 140 gallons in the main diesel tanks and fill up at the dock every year or two instead. I should also be able to add a few coils of copper tubing around the stovepipe and circ antifreeze through them and the hot water tank heat exchanger to have heated water for dishes and showering in the winter.

Being in Louisiania it's slightly humid. Actually any boat is a humidity and moisture trap. Many people use dehumidifiers and air driers, but they like 110Vac. I don't like 110Vac and the high power consumption of such inventions while on anchor. AC and a diesel heater will help remove moisture throughout the year. Still, some sources of moisture seem doomed to exist in the boat. I use a propane bbq much of the time for cooking. The rest ot the time Silent Partner has a wonderful 4 burner propane stove with oven in the galley. Propane is nice to cook on, but part of the combustion process creates water vapor. Rather than intensifying the sauna effect in the cabin I want to add a stove hood with fans. I plan to use computer cooling fans (12v and very effecient and quiet) installed in the hood I'll have to build. I'll vent out the deck, with 4" deck plates I can block off just like the dorades for the foulest of weather situations.

At the same time I want to build a teak box to house the propane tank(s) on deck directly above the galley. It will be a sort of integrated stove vent propane box combination. This will place the propane as close as possible to the stove. I will also build rubber seals into the box lid and a drain out the bottom dumping overboard via a thru hull to vent any stray gas fumes out and away. This will be a great improvement on the current arrangement, which places the tanks on deck all the way up forward. Besides the cost of running a 30' propane line, every time I activate the solenoid valve it takes 30 seconds or more before the gas actually reaches the stove. That's also a lot of line for propane to sit in and leak out of should a valve on the range ever stick.

RELIANCE, a Cal 46

My parents boat, also aquired through an insurance auction of damaged vessels, a 1977 Cal (Lapworth designed) 46' center cockpit. One of if not the first truely functional center cockpit raised salon vessels ever designed and put into limited production. The Cal 46 is considered one of the few most stoutly built and comfortable liveaboard/cruising boats of all the vessels in existance today.

A few interrior pics at initial aquisition. No cleanup has been done at this point. The layout is functional and roomy. Head off aft stateroom includes a shower. A second head is forward of the main salon.

Reliance arrived equiped with a hefty 4 cylinder large displacement Perkins diesel, and a 4kW diesel generator. The main engine is in excellent condition, with features such as a remotly mounted oil filter, dual racor fuel filters with cockpit mounted vaccum gauge, engine driven bilge pump in case one should ever be needed, and elaborate monitoring and alarm system (if engine gets a little warm or oil pressure drops a nav station buzzer, engine room bells, and mast mounted loudhailer all notify the skipper of the condition). Even after having slept for nearly nine months the main engine fired up instantly after jumping the batteries. It starts every time with a light flick at the start button. I don't think it even makes two revolutions of the crankshaft before firing off. (Actually it starts more easily than the brand new Yanmar in the Hans, and Yanmars are known for quick and easy starting).

The engine driven (mechanical clutch engagement on demand) bilge pump

Fuel filters, sea strainers, ancient but yet very effective (though should not be left unattended to prevent overcharging) battery charger

The generator, mounted in a wood enclousure to insulate the sound.

The starter brusher were worn out, but $4.00 and an hour later it fired up.

Main electrical panel at the nav station. Also at the nav station are controls for the Vigil inverter, radar, RadioDirectionFinder, Depth, wind, and knot log instruments, AC and DC voltage and amperage meters, VHF radio, Jensen stereo, printer (for weatherfaxes), a loudhailer, and engine alarm panel. A bronze Baramoter/Thermometer (Weems and Plath) is also mounted for easy viewing at the station. Below the tabletop are drawers containing spare parts, winery, and paperwork on all the installed equipment and documentation of additions, wiring, plumbing, rigging, running gear, and other such papers.

BAck side of the electrical panel (accessed from the engine room) is actually very clean and neat. It's easy to trace any wiring and all is properly secured against movement or chafing while under way. Very few boats, especially those that aren't direct from the factory, have decent wiring.

The batteries. Presently 2 8D batteries but soon to be replaced with 6 6v deep cycle golf cart batteries (far superrior in tolerance of viberations, repeated deep discharges, and with more years of life in general). Bus terminals and battery switches from Blue Sea Systems will also be added.

The water system includes a new pressure pump. There is also an expansion chamber to reduce pump cycling. The stainless hot water tank features not only 120vac heating coils but a heat exchanger to heat water off the main engine cooling system.

Diaphram style bilge pump. Far more desired than rotary type submerged pumps with boats of the deep sump and draft type such as sailboats.

The only major damage was to the starboard forward corner of the raised saloon cabin. The hull had a few minor scrapes as all the boats from the marina in Slidell, bent stanchions, and some other bent railings. The main mast spreaders and upper and lower stays on the starboard side of the main mast were also damaged. None of the damage was as bad as it appeared in pictures. The cabin damage in particular was not extensive (beyond a few hours with some fiberglass and foam coring material). After removing the old headliner panels the entire cabin looked much better.

Both masts were straight and undamaged. They're also keel stepped for excellent structural properties. Keel stepped masts typically fair better under emergency situations and storm damage (if it should ever happen, like if ever sailing the southern ocean in winter with 60'-150' waves) in that the mast or at least part of it will stay with the boat should the stays part. The jib and main sails are both on roller furling, the mizzen conventially raised on a track. There is also an inner forestay, I assume for carrying a storm jib. The main mast also still has tracks affixed so a conventional main sail could easily be used. A partial height secondary track is also proply mounted to handle a storm trysail. The main mast also includes steps for going aloft with a harness instead of having to deal with a bosun's chair. There are also mast pulpits to lean against when handling sails, one removed because of cabin top damage but neither bent. An accidental jibe preventer is also rigged on the main boom. Apparently the previous owners didn't want to get boomwhacked while sailing downwind in light air.

All winches are in good condition, most still have the canvas covers on. The main jib winches are also self tailing.

Cockpit mounted main engine panel with gauges.

Propane tanks. The propane system includes a solenoid valve so the propane can be shut off from the galley without going on deck. A good safety feature that encourages shutting off the propane supply when the heater or stove is not in use.

A few things the auction company forgot about... 6 person liferaft hidden under a cover just forward of the mainmast.

...Oh, and a gas powered compressor rigged for filling scuba tanks.

Besides an electric windlass forward, there's also one aft with rope, chain, and danforth anchor.

...Oops. When we salvaged and towed the boat to Madisonville and the boatyard (Riverview Marine Services Inc.) we didn't get around to cutting the lock off the aft deck locker. Unknown to the auctioneers it contained all the sails, and thousands of dollars of spare parts. There are enough oil filteres onboard to motor from California through the Panama Canal to Florida and back. (as well as water pump rebuild kits for the engines and fresh water system, diaphrams for the bilge and shower sump pumps, rigging parts, outboard parts (boat included a 5hp nissan outboard in damaged but likely salvagable condition), sail repair equipment, spear gun, boat poles, spare VHF radio, and other such things.

Some of one of the two main anchor chains up forward.

Reliance, Silent Partner, and the Watkins 33 I lived aboard April 2005 through April 2006 (now listed for sale). No, the rest aren't mine, just ones the yard was in charge of looking after (that I had to keep afloat and properly moored for a few months while the previous owners and insurance companies haggled around.
