Ceramic filtration

After a couple of false starts, Steve on s/v Siempre Sabado has a working 5-micron water filtration system aboard.

As I was walking back to Siempre Sabado yesterday afternoon, it seemed to me that she looked like she was listing a bit to port. Down below, a glance at the inclinometer confirmed that we were indeed leaning to the left. Not a lot, but some.


Since we haven't changed what's on board, haven't added or subtracted fuel, etc., this can only mean one thing: the water tank is getting low. I had been kind of hoping this wouldn't happen until Lulu returned because she's bringing me some plumbing to make the filter installation neat and tidy. But, she won't be back until Sunday so I decided to bite the bullet and jury-rig the filter setup so I could fill the tank with filtered water.

As I explained in an earlier post, mounting a ceramic filter at the point of use didn't work very well since the foot pump just didn't have the oomph to suck the water through the 0.9 micron pores in the filter element. Pushing the water through the filter with the foot pump was even less satisfactory. However, I also knew that I didn't really want to run every drop of water from the dock hose through the ceramic filter to fill my tank with ultra-filtered water because, if the dock water had any suspended solids in it, it would take forever to fill the tank because the ceramic filter would plug up so quickly. You might remember that I went through a similar experience with fuel filters.

So, here's what I ended up doing...

All the water going to the tank is first run through a Rotoplas 1 paper filter. In the earlier post I referred to this as a 5 micron filter. It isn't. It's a 50 micron filter which is still pretty freaking small. I connected this in series with my new TurMix ceramic filter. The Turmix doesn't have nearly as much information on the ceramic element as the other ceramic filter I bought, but I'm assuming (hoping) that it is as good or better. One thing it has that the other unit didn't is an active silver element in the center for control of pathogenic bacteria. Nice touch.

Here's what the system looks like:

Notice the belt and suspenders approach here? The little squirt bottle is BacDyn, a local product with an active ingredient of colloidal silver for disinfection. We give the tank fill tube a few squirts of this prior to filling. Then, from the right: white supply hose carrying dock water; black Rotoplas filter housing containing 50 micron element for removing most of the suspended solids from the water; bright and shiny TurMix ceramic filter with silver element for removal of very small particles as well as most bacteria; and then the clear hose into the tank.

From the tank, we draw water through another Rotoplas filter housing. The difference is that this one uses an activated charcoal element with yet again, more colloidal silver and, presumably, a finer micron count than the 50 micron filter.

This water goes from the tank, through the filter, through the foot pump and out the faucet. This secondary filter is just protecting us from anything that might have already been in the tank before we started filtering our incoming water.

I just checked my stash and I see that we have tons of the 5 and 10 micron filter elements I bought in the US for the unit that filters our watermaker's backwash water and they will fit the Rotoplas housings quite nicely. It should be a few years before we have to buy any new filter elements.

This is what the new filters looked like before I started running water through them today

And here's what they looked like after filtering roughly 50-60 gallons (a scientific wild-ass guess) of water:

You can see that the primary filter doesn't show much of anything but the ceramic is coated all around with a light coating of brown stuff. This stuff washed off easily with just a wet dishrag. For the record, it took me 3X as long to fill the tank with filtered water as it did with unfiltered but, fortunately, I didn't have to stop partway through to clean the filter to restore flow.

So that's our filtration system. When we're making water with the watermaker, the only filter that will matter is the final one. But, I'll let you know in a few months how everything is panning out after we have a little experience under our belts.

Smart plug

Over at s/v hello world, Jason gives a nod to a product that is pretty new to the market, and one which you may want to consider:

We have a few safety rules on Hello World. Somewhere in the top five is: DON'T LIGHT THE BOAT ON FIRE. We had a few incidents here and there (for the record, melting butter in a plastic dish on top of a burning diesel heater is not a great idea), but by and large, the biggest risk right now while we're in a marina full time is our shore power cable.

Our marina is full of stories of boats either lighting on fire or almost lighting on fire from shore power cables working loose and heating up from the electrical resistance in a loose connection. Standard twist-lock shore power outlets are notorious for this.

I finally got around to installing a Smart Plug. Smart Plugs replace the shore power outlet on the boat and boat connector plug on your shore power cable. They provide a much stronger physical connection between the outlet and cable than the ordinary twist-lock plugs. And they have a thermostat inside that will cut the power if the connection ever starts to heat up. [emphasis mine -Ed.]



No going back now.


Relieved to find clean copper wiring inside our shore power cable.


Half the plug installed.


After many F-bombs and a couple bloody knuckles, I finally got the old shore power outlet out of the boat.


Wired up the outlet.


Finished.


I did some forensic analysis after I was done. I found signs of overheating on the old shore power plug I cut off. There was some discoloration on the plastic and some melting. I have no idea how long before that would have manifested into smoke and fire and OH THE HUMANITY but I'm pretty relieved I headed off the problem before the boat caught fire.

Disclosure: I have a friend that works at Smart Plug. And yeah, I'd really like to see the company take off and for them to make cement trucks full of money. However, what I'd like more is for my boat to not catch fire. Whether I knew anyone at Smart Plug or no, I'd be all over recommending this product.

Seriously, if you have a boat, buy one of these things.

Sheep: 1; Barnacles: 0

Mike of s/v Chalice has a simple tip for keeping your prop clean.  Given Washington State's recent banning of all copper-based bottom paint, we may be smearing this over our entire hulls.

Do you hate cleaning barnacles off your propeller?

Once cleaned, just cover with anhydrous lanolin. It's fairly cheap and stays put. It can be applied under water and is totally Eco-friendly. If you use your boat you will have to reapply. Not sure how long it will last, but it's fairly cheap and it only takes a little. It is grease made from sheep's wool. Just warm up the container to make it easier to apply. Side benefit is that it will make your hands nice and soft.

Sticky Stuff That Unsticks Other Stuff

Over at Dock 6 Brian has an old boat which he is dismantling for its parts: DonorBoat.  But that task has its problems...  He's found a product you probably need in your toolbox:

   DonorBoat destruction has meant unbolting and unscrewing hundreds of, er, bolts and screws.  And nuts.  And washers. All bedded just as they left the factory.

   Stainless screws and bolts installed through aluminum cleats and tracks, all bedded with caulking that was still tenaciously goopy all these years later.

   All of it was removed without a single stripped fastener.
  Not one.

   I'd love to be able to take credit for this fortuitous feat of fixture and fastener finesse, but it weren't skill.  It was Screw Grab.

   I am not a chemist or an engineer, and I have no idea what the actual secret ingredient or process is, but, in simple terms, Screw Grab Friction Drops is a grip enhancer.  Got a recalcitrant screw?  Squeeze a drop or two onto the screw head, insert the tip of the screwdriver and turn.  It is that simple.  And it really works.

   A little goes a long way.  I bought a bottle of Screw Grab from Lee Valley Tools  almost a decade ago, and  have more than half the bottle still remaining.  It might be the best $6 you invest in your toolbox.

   There was one casualty of the Fabulous Fastener Follies- one Phillips screwdriver.

Busted the tip unscrewing backstay chainplates.

Like I said, this stuff GRIPS.

 

Best portable bar. Ever.

Brian over at Dock 6 has an offer you cannot refuse...

So there you are, invited for vittles on a boat across the bay.  Being the good guest you are, you load a bottle or two and  some cheese and crackers in a bag , jump in your tender and get gone.  You arrive, climb aboard, and share out your lukewarm bottle, sweaty cheese and broken crackers.

     Impressive.

    Or say you want to go for a day sail with friends on your Siren.  You can load a cooler and a grocery bag, and wine glasses and ice and cutting board and cutlery and then you don't have room for your friends.

     Oooooh, dilemma- do we sail with our friends and leave the booze on the Dock, or take the booze and leave the friends?  It's an awkward choice.

     Here on the Dock, we've found the solution, thanks to the coolest cooler company ever, California Innovations .

 

    Meet Product #78124-90-09, or, as we know it here on the Dock, The Porta-Bar.  The Porta-Bar is a rigid soft-side cooler/picnic basket hybrid loaded with features.

  Open the front facing zippered "lid", and the first feature you notice is the thin plastic cutting board cleverly attached to the inside surface of the lid with stretchy elastic bands at each corner, making it both secure and removable for cleaning.

  Inside are three adjustable compartments.  The walls are easily removed and reinstalled thanks to the velcro tape fasteners.  Nestled inside these compartments are a tall bottle carrier,(Warm Bin) an insulated ice box/topload cooler (Chilly Bin), and a plastic bin with lid (Cool Bin).

   The Warm Bin will fit as many as three 40 oz bottles of rum, or two 2 litre soft drink bottles, or a vodka bottle and a Clamato juice bottle or  a bottle of wine, a couple of glasses and a baguette.   This baby is versatile!

  The Chilly Bin is cleverly designed.  Inside the soft bag is a plastic tub, perfect for holding ice cubes in addition to up to 12 soft drink cans.  To maximize cold life, the lid has a small velcro sealed hatch, perfect for quick soft drink extraction.

       Above the Chilly Bin is the Cool Bin, perfect for storing lemons, limes, cheese, sausage, sandwiches, all sorts of snacks.

    The handles are sturdy, the stitching reinforced and the fabric is easily cleaned.  The only quibble, and it is  minor, is the lack of a carrying strap.
     
      All in all, this is a pretty impressive package, especially at a retail price point south of $40. Like it?  Want one?   There is only one problem...

    According to California Innovations, Product #78124-90-09 is No Longer Available.  If enough demand is generated, they will consider putting it back into production.  Fire them an email, let 'em know you saw it here and you want one, bad.  Service@ca-innovations.com

Barring new ones rolling off the assembly line., my local Canadian Tire still has a few in stock.  If anyone wants one, drop me a line, and I'll set you up.

UPDATE:  I have sourced about a dozen of these, which I am happy to move on at $35 each plus shipping costs.

You know you want one (what a great gift!). If you send me mail at SmallBoatProjects at gmail dot com, I'll forward it on to Brian (note that he is in Canada - not sure how that complicates things...).
