More Drive Train Progress

Thought I would give you guys a quick update on some of our recent progress.  Here's a shot of the 4.7 KW motor with the shaft adapters in place.  I was delighted to see they actually fit.

The shaft adapters fit, wonder of wonders.

Here's one with the motor mount fitted.  This thing is gonna be a beast to drag under the cockpit and hook up.
We've got a few nice, less than the center of the sun heat days, so I'm hoping to get all this stuff together and tested.  Today we'll be attaching the connections to the motor controller and checking it out.  Wish us luck.

Dealing with Heat

The weather this year has been nuts (and I'm afraid that may be the new normal).  We had something like 14 days of rain in a row, and now we're going into our eighth day of heat warnings, with heat indexes that have soared into the 116-degree (Farenheit, that is.  That's over 46 degrees Celsius) range.  Neither the wife nor I were raised with air conditioning (she in Wisconsin, me in Florida) and neither of us really like it.  As a result, Tesla's Revenge  like Floating Empire before it, has no AC.

yeah.

In any case, weather can change the way you deal with your daily routine, and living on a vessel and that much closer to nature, you feel it more.  Wind knocks you around in the slip or at anchor, heavy rain makes conversations aboard impossible, cold can rather trap you aboard in winter.  As with everything, you adapt, you take the conditions into consideration.  It's a part of living aboard.

Now as to heat:  you have to watch your butt with heat.  It's exhausting. It, like extreme cold, makes even the simplest things more difficult, and like extreme cold, it can kill.  I was returning to the boat yesterday and ran into one of our slip-mates.  He looked like absolute hell.  "I got sick." he said.  He'd been working in the sun, re-doing his hull, sanding, painting. . .he got overcooked.  It happens, but heatstroke is nothing to fool with.  In our friend's case, he retreated to the cabin of his air conditioned boat to recover.  Mulling on it, I realized, we don't have that option.  So I thought I would pass along some of  the ways we deal with the heat, some of the ways we modify our behaviours and schedules to make life livable.

First of all, it must be said, most of the year it isn't an issue.  Water tends to come with it some lovely breezes and moderates the temperatures, even in the tropics.  This week-plus blast of temperature has been an anomaly.   Most of the time, spring, summer, and fall, the temperatures are moderate, the waters refreshing, and it's pretty pleasant.  Sometimes, however, nature fails to cooperate.

We try not to be stupid.  When the heat index is over 100, you're not going to be working on deck, or in enclosed, poorly ventilated spaces.  I don't care how much you "need to get things done" or how much free time you may have to work on the boat, you're not immune to the heat.  Worse, when you do get heat-affected, you tend to get stupid and make poor choices that are at best counterproductive and at worse, dangerous.  When the forecast is "this week, expect the third ring of hell during daylight hours" you need to re-make your schedule accordingly.  Do paperwork.  Read. Nap.  Just accept the fact that, living aboard, you live closer to nature and have to partner with it, even if inconvenient.  I watch our beloved ship's cat Magellan in the heat.  He naps up on shore in the shade and the breeze, or parks himself on the galley table in front of the fan.  I make sure he has lots of water when he needs it.  You need to do the same for yourself.  If you're not behaving like your pets in the heat, you're doing too much.

Magellan is disamused by the heat.
One of the other reasons we have no AC is that Tesla's Revenge is all solar-electric, and power management is an issue.  Air Conditioning compressors eat a lot of power (as does refrigeration ).  We were afraid, with only so much deck space for solar panels, that the draw would be excessive.  Fortunately, there are some simple, low power options.  The market has recently be flooded with a plethora of USB powered fans that can efficiently provide you with spot cooling and can clip anywhere on the boat.

These little 5V USB fans can clip anywhere, take little power, and can make the difference between typing and sticking to your keyboard (which this one is doing at the moment).
 Another great option is the venerable box fan.  They don't eat up a lot of power, move a lot of air, and can flush the hot air out of your entire vessel.  Just position at one end, open the hatch at the other, and let her rip.

A staple in pre-AC days, the box fan is still a durable and effective way of moving air about.


Nights can be a challenge.  There are few things more unpleasant than being there in bed naked, uncomfortable, and bathed in sweat.  Fans, of course, help.  We have, at times, resorted to the "redneck air conditioner" technique of sitting an ice block (frozen water in bags from wine boxes work well btw) in front of a fan.  It's short term and inefficient, but it works.  The heat has led some folks to creating some great DIY versions that are far less wanky and more usable .


.

There are even commercial versions available now


We've used a lot of other techniques, from soaking hats to draping towels over the fans.  All of them work and can make your nights a little less miserable.

And remember, if things get nasty, you're on a BOAT for pity's sake.  MOVE!  Go find some nice cove with a nice breeze and anchor out.

Stay cool, guys.

Of course, some cooling options are better than others. . . .

A compendium of small and useful things

Well, having done with my tenure at a big box store to build up some cash for boat revisions and whilst waiting for parts and paperwork to arrive and for my knee to recover from the concrete floors (ow) at work, I thought I'd reflect on some of the small things we've learned this year.  Little stuff, but nontheless important.  Ready?  Here we go.

On Composting Toilets
This was so easy, why didn't we do it sooner?

It really amazes me, now that we have a functioning urine separator, how much of the bulk of human waste coming out of the boat is pee.  Not just by volume, but the bulk of the odor, certainly, is urine.  By comparison, solid waste is virtually undetectable, smell-wise. We wind up emptying the 1.5 gallon urine container about every two days, but the solid waste can go ten days or more, depending on how much we stay on the vessel.  Like I said in an earlier post, we shoulda done the separator ages ago.

On Solar Systems
When it comes to solar systems, size--or at least capacity--DOES matter.

The addition of the new, heavier battery bank has been a bit of a revelation.  Since it's installation, our system has only needed once to go back onto shore power, and that was before the last four of the 100AH batteries were installed and at the end of a period of ten days of rain and overcast this spring.  We were clearly wasting power before, our 650W system generating more power than we could store.  Currently, we're running our lighting, electronics, and refrigeration 24/7 without taxing the system.  So if you're wondering about the configuration for your boat or tiny home, put your cash in the storage.

On Water Systems
Both the pump in the background and the one in the foreground failed within a few months.  Bah!

Manual marine potable water pumps suck (both literally and mechanically).  In The Floating Empire, our water system was a traditional, cast iron pitcher pump, which worked beautifully and without complaint.  We have now been through FOUR hand galley pumps in our current vessel, one piece of Chinese-made crap after another.  None of them has lasted six months.  Some didn't make it six days.  It's dispiriting.  In the next iteration, it's either going to be a pressurized system or back to the cast iron pitcher pump.  At least you can count on them.

On Boat Cats
Magellan rocks.

Get one.  They're adorable.

We're both jonesing to get the boat up and at sea.  More in a couple of days as we get closer to this.

Magellan Speaks

It's about TIME you got off the computer so I can use it.
Magellan here, first Ship's Cat of the Tesla's Revenge. I thought, since the Captain and First Mate were off ashore doing human things that I would address the sad lack of articles in this column about. .well. . . .me!

I came to life aboard as a mature cat, a “rescue” in human parlance. I had been living with a family that dumped me when they bought a couple of obnoxious Corgis and was fortunate enough to have run into my new people at the shelter. Their former Ship's Cat, Kallisti, had just passed on and they were in dire need of a new companion. I made it clear to them that I was a people person, the perfect personal assistant for two artists living on a boat.

Fortunately, they bought it.
Sometimes living with artists can be a challenge.

I had never lived on a vessel before, but was surprised that they seemed tailor made for cats. Boats have lots of little spaces to explore and into which one might tuck ones self. During the days I can sit in the sun and watch all manner of birds and fishes. The ducks are especially friends of mine, which I refrain from trying to eat. Frankly, we get along splendidly. At night I can sit in the cockpit and watch the water and stars, or go belowdecks and sleep with my people. I have my own litterbox, which they keep (mostly) fastidiously clean. I have a waterbowl which I love to drag around, and the food is good. It is, all in all, a wonderful lifestyle for a cat.

But there are some challenges to being a truly great Ship's Cat (and I suppose, by extension, Ship's Dog, though I can't imagine that) that I thought I might detail to those of you of the furred persuasion that aspire to this life.

First of all, boats are small spaces. For my part, I genuinely like my people and like being around them. Even when they are off the boat, I follow them about to make sure they stay out of trouble. Like I said, I'm a wonderful personal assistant. If you are of a more solitary bent, though, or dislike constant human contact, this might not be the life for you.

Then there is the matter of the space. As I said before, boats seem created just for cats, with so many interesting crawlspaces, defensible positions, and overlooks available for our use. But the small space means you've got to be good with your aim vis-a-vis the litter box, and consistent in it's use, or you will most definitely come into conflict with your humans.

The water and weather can be an issue as well. Rain on a boat can be LOUD. Wind can knock us about, which I do not like at all. Though I've never suffered from it, some Ship's Cats (and presumably other pets) can become seasick, which would be unpleasant. The weather is just something with which one deals on a vessel, but it bears considering. As to the water: I am a sveldt (okay so I'm big boned) graceful creature of amazing coordination, but occasionally—just OCCASIONALLY, mind you—the boat moves just the wrong way when I'm coming aboard or walking down the gunwale and I, um, miss. Living on a boat means you really need to know how to swim, and being able to climb up the dock pilings is also a plus. As I say, it doesn't happen often, but it can happen. As it is, the few times the misfortune occurred to me, I just swam over to one of the pilings, climbed up to the dock, got aboard, and spent the next few hours putting my fur back in order.

Then there is the matter of other people, other spaces, and travel. First of all, Marinas are full of other folk, other cats, even dogs, and you need to be okay with that. People may, of course, want to adore you. That's only right and proper, and you need to be friendly and not a threat to them and their often clueless offspring, but you need to set limits and you need to be happy with staying close to ship when appropriate. Marinas can also be full of large, dangerous, terrifyingly loud equipment that could crush a kitty in a heartbeat. Even if you get to go ashore—and many of my compatriots do not—you need to be comfortable with keeping close to home. Losing your people or your people losing you would be awful.
The collar is not merely a fashion accessory:  It give me the power to locate my humans.

In that regard, if you'll notice some of my more handsome portraits in this fine publication, you may note a stylish diamond shape hanging from my collar. As fashionable as that is, it has a purpose: its a Tile, a bluetooth tracking device. With it, the captain can always find me with his phone if he needs me (and, not unimportantly, I can help him FIND his phone by a simple tap on the tile). It makes us all feel much more secure.
But taken all into consideration, if the minor downsides don't bother you, being a Ship's Cat may be a wonderful life choice for you. I feel fortunate that my people found me and gave me this opportunity to be with them in so beautiful a place. We're happy here aboard ship. I think you might be as well.

Now, if you'll excuse me, the ducks need me for something. They're amazingly stupid, but I'm happy to help. All part of the Job.

Of Progress and Experiments

So, nursing some cracked ribs, the work has rather slowed here aboardship.  Did manage to --carefully-- get a little bit done over the last two days.  I wired in our antenna, which I'd been meaning to do forever, and mounted our marine vhf radio by the binnacle.

This has only taken me. . .what. . . a year?
I was rather pleased with myself as I was able to trick up a mount for the radio using an old antenna rail mount.  Works pretty well, and as soon as I get the wires all wrangled, should be a pretty neat and convenient installation.

Here;s the new mount from the back.  Once I get the wires tided up it should be perfect.
That's about all I had the energy for, frankly.

Early on in designing The Floating Empire, we were casting about for refrigeration options.  Fridges are a problem.  They require power, have a surge of power at startup, they're bulky, and they often require ventilation around the sides and back.  It's an issue.  For a bit of time on Empire, we ran with just a cooler and ice (NOT economical), then installed a fairly efficient fridge, which served us pretty well, though it did tax our solar system.

Moving aboard Tesla's Revenge, we had to downsize our little fridge to an even smaller one (with a pretty useless freezer), and had been relying on freezing bottles of water on land to keep a cooler chilled to handle the overflow.  Meh.  It worked, but not conveniently.  A slipmate loaned us an ice maker, which was convenient, but also a major power hog.  In planning on doing some travel, it was clear that NONE of these options were really workable.

Then we remembered something we'd contemplated early on in the planning of our original vessel.  One of the most efficient of small cooling units you can find are small medical freezers.  They're REALLY cold (-17 fahrenheit or so), and well insulated and highly efficient.  We decided to give the idea another shot.

A large cat sleeping next to our new 2.1 Cu Foot Freezer.  The cat is on the left.


Accordingly, we've gotten a Whynter 2.1 Cubic Foot freezer (the same size as our original fridge) and put it in the cockpit where the ice maker usta live.  We'll be using it as a. . .well. . .freezer, freezing foods, making ice for drinks, and making ice to keep a new 40QT supercooler cold for our non-frozables.

We'll let you know.  I'll be ditching the fridge and turning that space in the galley into much needed storage.

Need a refrigerator?

More later.

Of Batteries and Damaged Ribs

. . . .not the boat's ribs, mind you, mine, but we'll get to that.

In the process of getting Tesla's Revenge ready for travel, we knew we had to replace the battery stack.  The current stack, composed of eight, 35 AH batteries ( and somewhat elderly ones at that ) was inadequate even for staying off grid most of the time, let alone powering the drive of the boat.  Accordingly and in our right minds and everything, we measured and, debit card in hand, ordered in 8 new, 100 AH deep cycle batteries.

Now before I get any further, yes, I know lithiums would have taken up less space and yes I know they weigh less and yes I know they have greater energy density, etc.  Yep.  Got that.  We just don't have the cash to lay out for Lithium-Ion cells at present.  Also I found a good deal on the lead acid gel cells we're installing.

But these things are a MOOSE.  Below is a photo of the new batteries next to one of our old ones:

They weigh like they look, just short of 80 lbs. each.
So we cleared out space for them in the bilge, putting in some new supports and anchoring in battery boxes to protect them.

Here's the center battery compartment.  The remaining four will go in the stowage compartments port and starboard.
Wiring up the new stack was a cinch since we already had the connectors, but lowering these monsters into place was another thing entirely.  Dropping in the third one, I slipped, came down hard on the compartment edge on my side, and something went "grunch".

Ow.  So now the next four are gonna have to wait a bit as I'm in pain and wrapped in elastic bandage.  The good news is the four we have wired in are working spectacularly.  We're off grid 24/7, just went through some major cloudy days with no problem, and, in general, we're really pleased.  Should have done this ages ago.

Lots more to do, of course.  We've four more to load and wire in, we're replacing our fridge with a medical freezer (surprisingly more efficient ), and then, of course, there's the drive, but we're making rapid process. . . .

. . . If I can just stay in one piece.

More shortly.  Enjoy the spring.

Turning a Futon into V Berth bedding

V berth bedding from futon

Liveaboards, in my experience, fall into two categories: 1) We have enough money to do this, so we're doing it, and 2) We don't have any money so we're doing this. We rather fall into the second category.

One of the greatest discomfitures of living aboard boats tends to be bedding. The reasons are many: Weirdly shaped spaces mean traditional mattresses often simply won't fit (and often won't even go belowdecks). A thick mattress takes up space you don't have, and, let's face it, most boats are regarded even by their manufacturers as pleasure craft, intended for only temporary habitation at best, and if your drunken friends wind up passing out on a three inch mattress, so be it. None of the preceding are conducive to a good night's sleep.

So it was with Tesla's Revenge. We've been sleeping in the V berth on 70's era foam which was, to say the least, beat down. It was long past time to do something. After casting about and looking at the amazing expense of foam, let alone the cost of custom cushions, we decided to take matters (and mattresses) into our own hands and try to find a mattress we could modify for the space.

Both being a fans of futon mattresses (okay, so we're old hippies), we thought we'd bite the bullet and see if we couldn't modify one to fit our V berth bedroom. After a bit of casting about, we managed to find an inexpensive, American-made (how the hell did THAT happen) futon mattress at a Big Lots for just under $100. The conversion proved to be surprisingly simple, and the results surprisingly comfy, so we thought we'd share.

Here are the two halves of our old, beat to crap V berth cushions and a new, American made futon mattress from Big Lots.

Peel back the cover, clipping the places where the mattress is sewn through the cover.

Here we go.  Here's the old cushions atop the stripped mattress.

Using a long carving knife and scissors, cut away the excess mattress stuffing.  Some of these mattresses are just filling, some have a foam center.  Either way, the process is the same.

Cut the excess mattress material away to match the original cushions.
Here's the trimmed mattress batting.  We left the top intact as we didn't need to cut it.

Pull the mattress cover back into place and fold it over the removed sections of the stuffing. . .

...and stitch the mattress cover back in place.

So here's the cut mattress with the cover stitched back into place, folded over the removed sections.
And here we are in the V Berth.  MUCH more comfortable.
The whole process took only about half an hour and I'm amazed we hadn't tried it before.  We slept on the new bed last night, with plenty of padding and no low spots.  This really worked well.  We're contemplating trying the same idea for new galley cushions.  Give it a shot.  There's really nothing to it.

We got lots done today on Tesla's Revenge, setting in new snaps on our roll-up plastic glazing (okay, so I miscounted when we installed it and wound up just screwing some of it in place), and putting in new lifelines to replace the nasty plastic covered stainless steel cable ones we inherited with the boat (the new ones are an aramid, and just as strong).  The new battery boxes showed up yesterday, and the new batteries Tuesday.  We're getting there, folks.

More shortly.

Apologia again

Sorry for the lack of activity of late.  I've been working at a big box store to be able to order some new batteries for Tesla's Revenge.  New batteries, new solar panels, and the final construction of our electric paddlewheel drive are coming up toward the end of May, and I promise to be better at posting in the near future.  For the moment though it's ten hour days and not a lot of movement on the boat.

So here's the cat tax.  Talk to  you shortly.

Magellan just wants to get back out onto the water.

Beware the Tides of March

Beware the Tides of March

Okay, so it's a terrible pun, but someone's got to do it. Last episode, I discussed some of the issues with inclement weather, but from our experiences this March, I thought I would do a bit more on the tidal issue.

I meet a lot of folks who think that the tides only matter in the oceans and in oddball circumstances like the Bay of Fundy. They think that rivers and lakes, estuaries and bays are somehow immune. Let me assure you, they aren't. Take a look at the two pictures below. One is a rain-driven high tide at our marina on the Middle River. You may note that the water is within a few inches of swamping the fixed piers. We've seen worse. A few years ago, a November high tide sent the docks a full ten inches under water, which made getting to one's car a bit. . . um. . .more entertaining than usual.
This is about as high as it gets without getting one's feet wet, though we've seen it 10" over the docks.

The second shot is from roughly the same vantage point in our wheelhouse, but this after two days of winds gusting from the NW at 60+ mph. What you are looking at is mud, and yes, the boat in the background is the same boat in the same slip. The disturbing part: This is HIGH tide.
Mud mud mud mud mud

My point is, you're never immune to the effects of tidal and wind driven water, nor of coastal flooding from rains upstream, and if you're wise, you'll plan for it. But how?

There are several tactics to deal with monster tides. The most common being the humble footstool, which is easy to keep on hand and has other uses....they also blow off the dock rather easily. If you'll look next to the dinghy in the low tide shot you'll see a sort of lump just behind it. That is the zebra-mussel encrusted stepstool we lost last year. Caveat. We also use a handy section cut from a discarded ladder to get both up onto dock and DOWN onto the dock. . . .depending. If you cruise, you'll find tide conditions different in every region in every port, from variances of inches to variances of tens of feet. Do your homework and you won't be stranded on the vessel begging people on the cell phone to come and throw you food.
A stub ladder like this is easy to carry aboard, but can get you on and off the boat if the tides get ridiculous.

This late winter has been one of multiple projects, most quite successful. Our enclosure of the wheelhouse with FlexOGlass continues to make for some lovely afternoons sitting in the sun, despite cool temperatures and wind. This month, we designed and added a urine separator to our simple composting toilet setup (for instructions, see here) which has made a HUGE difference in how often we must empty the waste (we're now getting ten days or so between having to dump the bin), so I recommend that highly.

The weather has been hugely erratic of late, but spring is only around the corner. Slip mates are popping up like crocuses to look at their boats on the hard with longing. The marina is doing repairs and making ready for the boating season. We can't wait.

Rather a Lot of Updates

What a calm sunset should resemble.

 So, with so many projects in the offing, I thought I should do a post to bring you guys current with a bunch of them.  Here's a lovely evening shot at the marina.  The last few days were NOT like this.  The winter storm that went through bombification and unloaded on us here in the east was one of the worst we've experienced here at the marina.  Chief among the effects, aside from knocking the boat around quite a bit in the slip, was to blow virtually ALL of the water out of the upper Middle River and left us stranded in the middle of a mud flat, sitting some five feet below the dock and rather stuck on the boat.

This not water.  This is wet mud, and we're embedded in it.
Fortunately, it only lasted a day.  Now, I know half of you guys are asking yourselves, "with 65mph winds, how did the plastic glazing on their wheelhouse hold up?"  See, I do pay attention.  The answer is:  amazingly well.  We had no apparent damage of any kind to the FlexOGlass sheeting or our Gorilla Tape seams.  It was noisy as all hell, but it seems to have held up just fine.

The urine diverter we fabricated for the composting toilet was a real lifesaver during the storm.  It kept us from having to get off and dump the toilet during some really nasty weather.  At present, we're having to empty the 1.5 gallon pee bottle about every two days and the solid mass from the toilet itself about every 10, which beats the hell out of what we were having to do beforehand.  In summary:  if you're on the boat more than two days running a week, build one.

Now the water has--mercifully--returned to the river and we can get off the boat without a ladder, the winds are fading, and life is returning to some semblance of normal.  Looking forward to some calm days, some decent writing time, and the coming spring.

Much more coming,

M
