Fresh Water Pump Failure

With Maya's arrival along with all our existing obligations we've been busy and I haven't made much progress on projects recently, in particular is our new refrigeration which is moving forward but not quite complete yet.  Some unexpected projects do come up that jump to the top of the priority list and, in some cases, basically need to be done immediately.  One such project this month was the replacement of our fresh water pump.

The water that feeds our sinks and shower comes from a 130 gallon tank with what's known as an automatic fresh water pump.  Some boats also have a shore water port that connects to a hose pressurized by the city or marina feed which replaces the need for a pump when at the dock but Junovia doesn't (although may at some point in the future).  We use our fresh water pump a lot, especially because we shower aboard and now have an infant that requires lots of bottle/diaper liner/etc. washing.  So, when our pump started acting up early in September it was certainly a concern.  I should have just replaced it at the first sign weeks ago but instead waited until it stopped providing any water pressure during a weekend race to St. Helens and back.

We managed to get through the day using water from a cooler and filling a kettle whenever the pump would provide a little stream but it pretty quickly became a major issue that couldn't wait.  So, Sunday morning before departing St. Helens I pulled the failed pump and installed a smaller non-automatic pump we had in the spares inventory to get us by.  This actually worked surprisingly well and we even limped by on it for a few more days including for showers.  The only real downside was that you had to turn it off at the breaker panel between uses.  A device called an "accumulator" stores some pressure and allowed the sinks to work for short bursts without the pump so we really only had to run it every few uses at the sink.  A big pain, however, was when taking a shower someone else would have to turn off the switch or you'd have to jump out before getting dry to flip it yourself.  So, this needed a permanent fix asap.

Long story short I purchased a Shurflo Aqua King II 4.0 GPM for about $150 which came with hose barbs and the same plastic strainer we already had.  Installation was easy using the existing barbs and strainer, it provided an opportunity to replace the poor electrical crimp connectors with better replacements that include heat-shrink crimped on with a proper tool.

The new pump isn't much quieter and basically works identical to the 4048 before it started failing.  If I have to mess with it again I'll likely install a larger accumulator and look at mounting the pump to a different surface to further reduce noise.

Baby on Board

Our new crew member, Maya Jo Powning, was born via Cesarean Section 15:03 August 3rd, 2015 at Legacy Emanual Medical Center in Portland, OR.  With how quickly she was growing and the risk of loosing her if the Vasa Previa vessels broke Tara's doctors recommended we pull her out at 35 weeks.

Everything went surprisingly well considering she was 5 weeks premature.  The procedure was normal without complications and Maya came out screaming and kicking at 5 pounds, 6 ounces and 18 inches tall.  We were prepared for her to have to go into neonatal intensive care for a couple weeks but because she was able to breathe on her own with good oxygen levels in her blood and started eating, pooing and peeing within hours of her birth she stayed with us from day one.  The hospital kept a monitor on her to watch her blood oxygen and heart-rate but after 24 hours everything looked good so that was removed and she's been detached from any machines since.

Four more days were spent in the hospital for Tara's initial recovery and to make sure Maya stopped loosing weight.  Today is number four with her aboard Junovia and everything is great so far.  We're feeding her every three hours which is a bit exhausting but have gotten used to it.

Getting started feeding a baby born by c-section is complicated in itself, on top of that we have the added factor of her being five weeks premature.  A really great thing about this hospital is they gave us the option to use donated breast milk (instead of factory formula) until Tara's milk came in which took a few days.  So every few hours a nurse would bring us a container of human milk.  After an initial "training session" on Tara I would feed her using my pinkie and a syringe while Tara hooked up a breast pump to get her body going.  Initially we fed her 20 milliliters per session and increased to 35 before getting discharged.  On the third day Tara's production jumped up enough that we were able to ween her off the donor milk and use our own.

At this point she weighed 2.235kg, a little under 5 pounds, so had lost some weight but was leveling out and on the up-swing.  I don't recall the exact weight but Sunday we had our first follow-up and she had gained a bit which means things are going good.  We're currently supplementing 50ml using a bottle after she gets some directly from Tara and she's been able to get enough directly from Tara on a couple of feedings.  Sucking all her food directly from Tara at this premature age wears Maya out so we'll be giving her the bottle as well for a while even when Tara is around.

Tara continues to experience a fair amount of pain despite heavy pain killers and is taking it easy.  They cut through a number of layers during the C-section and it's a bit of a shock to her system to have the baby and placenta suddenly removed.  It takes weeks for the uterus to contract back to a normal size.  Hopefully she'll be mostly back to normal towards the end of August.

So, yay!  We are very fortunate and stoked new parents of the cutest baby ever.  Now to find the perfect sailing dinghy for her...  Anyone have a nice El Toro for sale?

We're Pregnant!

Well, we've been pregnant for a while.

It seems I have yet to share this on our blog but early this year we succeeded at boot-strapping our first child with a due date of September 7th, it's a girl.  Unfortunately, and fortunately because we caught it early, Tara was diagnosed with a condition called vasa previa.  The placenta is made of two parts separated by exposed blood vessels which cross the cervix.  Our baby is healthy and everything is going fine otherwise but there is a risk of loosing her (the baby) if the vessels break which could easily happen if the cervix dilates.  This also means Tara will not be able to experience a natural birth and instead will have a planned Cesarean section.  Also, as a precaution, last week at 30 weeks, she has been admitted to Legacy Emanual hospital for continuous monitoring.  If she starts to have contractions, the cervix dilates, or it looks like anything is happening they can have her ready for an emergency C-section in minutes.  We're hoping nothing changes and we can go into a planned C-section at 36 weeks which would be around August 10th.  Now we're definitely going to have to find a sailing dinghy for our kids to learn on.  Unfortunately Oregon doesn't allow you to drive any motorized boat (sailing or not) until 12 years of age, so I guess our kids might learn to sail a real boat on the open ocean.

Anywho, we're reaching the end of her first week in the hospital and Tara's doing well considering.  They're not letting her do any cardio exercises but she's finding ways to keep from bouncing off the walls.  Her setup is pretty nice with a comfortable room, internet, great nurses and plenty of visitors.

More to come soon...

New Fire Extinguishers

The Coast Guard requires at least 3 type B-I or one type B-I and one type B-II portable fire extinguishers aboard recreational boats between 40 and 65 feet.  We did have 3 type B-I's but during the survey these were called out as a safety issue for not being tagged.  They were all within the green and appeared in good shape so I probably would never have messed with them if our insurance company didn't demand we resolve the survey findings (before April).

So, yesterday, Tara brought them to a local fire safety company to have them inspected and tagged.  It turns out that because they're plastic and so old that two of them are no longer legit and the third would have to go through some sort of overnight pressure test because it's plastic.  I was also surprised to have them tell us that because the needles were in the lower end of the green mark on the gauges that they need to be recharged anyway.

So, $150 later and we have three new type ABC filled with monoammonium phosphate complete with 2015 tags.  Many boaters use B or BC extinguishers which are easier to cleanup after an incident but I'm trying to follow ABYC standards as much as possible and they recommend ABC.

Anywho, hopefully we'll never have to use them - and now I can tell our insurance company that we've complied with all of their requirements.

46 CFR 67.123 - Name and hailing port marking requirements

When we bought Junovia she still had a previous name, "Jenny-V" on the stern which Tara managed to get off using a 3M Stripe Off wheel in the electric drill.  Since then some time has gone into considering different designs, fonts, colors, etc. for new markings but in the end we decided to keep it simple.  We had basic vinyl lettering printed out by NW Sign Solutions where a friend works (thanks Sara) and they turned out to be pretty easy to put on.

We got a tip from friends on the dock (thanks Jay and Carolee) to spray windex under the vinyl to keep it from immediately sticking allowing us to make slight adjustments to the position and completely wipe out any bubbles.  This turned out to be a good idea and I'd definitely do it again next time.  Two things we did wrong were:

  • Not enough windex on one set resulting in immediate sticking and a couple minor wrinkles that took some effort to iron out.  The windex did make us a bit lazy about getting it right initially.
  • Got some windex on the port name before exposing the sticky side.  This prevented it from properly sticking to the backing paper that keeps everything lined up.  We had to wait much of the day for that windex to evaporate so the letters would again stick to the paper before we could put the port on.  It looked like we were going to be ordering a replacement but in the end it turned out fine.
After putting the vinyl into place and wiping the bubbles out we left the backing paper on for a few hours for the windex to evaporate before exposing the final names.  The process was initially a bit stressful for me but we're both very happy with how it turned out.

Electronic Projects

Helm Instruments
Warning: this post gets pretty nerdy as my primary boat project for February involved getting all the instruments and radio/navigation components integrated along with a bunch of wiring cleanup.  Much of the core of the electrical system was cleanly rebuilt before we bought Junovia but there were a number of rats-nests and issues remaining that were both unsafe and unwieldy to work with.

Radio Panel
Main Power Panel
An issue that was bothering me in particular was how all the low-voltage splices in the engine room were just sort of dangling exposed and all tangled up making it really difficult to troubleshoot or trace anything.  For this I mounted a sealed PVC box with a couple terminal strips epoxied inside.  It's become the nerve center for our data networks where information from the mast, helm and radio panel all come together and gets distributed back out accordingly.  We have NMEA0183, NMEA2000, Ethernet and SeaTalk networks along with a number of proprietary links between components such as remote mic's, depth sensors, radar, etc.  I added a Brookhouse eMux that integrates the NMEA, SeaTalk and Ethernet networks together such that all the data is translated between each protocol.  Our Ethernet includes WiFi which means I can get all this wirelessly on our computers, iPad, etc.  We can pull up OpenCPN on my Macbook and see all the nearby ships/tugs, how deep the water is under our sounder and even where the rudder is pointed along with just about everything else the boat knows.  Pretty overkill but I'm having fun with it and building some skills that will be useful for developing marine software or working on big yachts down the road.

We also replaced the windvane at the masthead and added ST60 Wind & Multi-Graphic instruments at the helm.  Feeding a new wire inside the mast for the windvane was the most challenging task of the month.  It took a couple attempts of attaching the new wire to the end of the old before we got a splice skinny and flexible enough to pull all the way through from the mast's top to the base, which is around 56 feet.  Our clearance from waterline to masthead is only 52 but the mast continues through the cabin sole and sits on the keel a few feet below that.  Tara was upside down in the bilge while I was hanging in a harness at the top of the mast, we communicated via radio working together to coax the new wire into place.  Need to remember to bring the camera and snap a picture of our busy masthead the next time I climb up there.

The less interesting electrical tasks included replacing the DC sub-panel that was based on fuses and a bit clunky with a new BlueSea unit using the same type of breakers as the existing main panel.  All the solid copper wires have been replaced with ABYC compliant stranded copper and I've disassembled and re-connected almost all of the AC outlets, most of which appear to be the originals from when the boat was built which are safe and compliant.

Next up is a quick post about getting Junovia's name and port on the hull.  Then it's on to the refrigeration project which I'm expecting to consume many hours, but should be interesting and will also involve a lot of learning.

January Summary

An update on what we were up to in January...

We're continuing to get small projects done on Junovia including more wiring changes along with cleaning up some pluming issues related to a water-maker that was removed.

On a scary note: the AC outlet in our aft head stopped working and when I took it apart I found a situation where a spade connector had come partially off the outlet screw and heated up enough to start melting plastic and completely disconnect itself.  This is the shared GFCI for our aft cabin outlets where we've been running a 1000 watt heater, so that's what generated sufficient load to cause the overheating.  After some research in the ABYC standards I learned that if open-ended spade connectors are used they must have the bent ends/tabs to prevent it from pulling out of the screw.  For AC connections like this you're allowed to run the wire directly to the outlet provided there's a plate between the screw-head and wire such that it's pinched between that and the terminal.  I eliminated the spade connectors and replaced the melted outlet with a new GFCI.  Need to go through the rest of the boat and rewire any other AC outlets that violate the ABYC standard.

Along with keeping our sailing skills honed and having fun racing on Elixir in the CYC Sailing on Sunday Series we got Junovia out of her slip for a two night trip to Sandy Beach on Government Island.  This included motoring up river in the dark Friday night, a nice sunny Saturday practicing maneuvers and sailing around in wonderful west breeze followed by a rainy trip back to Salpare Bay early Sunday morning.

A very exciting development is that after just a couple months of trying Tara is now pregnant.   So, we'll need to start preparing the boat for additional crew.  Really hoping everything goes well and looking forward to raising a serious boat kid!

Also, I spent two weeks at Flagship Maritime in Tacoma going through classes for USCG credentials.  My complete application package got turned in Jan 20 and I've been getting email updates from the coast guard every couple of days since as it goes through their process.  Expecting to have a 50-ton Inland Master Merchant Mariner Credential with endorsements for towing and sailing soon.  This officially earns me the "Captain" title along with the ability to do more paid work on the water.  Here are the direct expenses I've paid for getting my captains license:

  • Transportation Worker Identification Credential $129.75
  • CPR and First Aid Online Certification $39.95
  • OUPV Course and Exam $900
  • Masters Course and Exam $300
  • Towing Endorsement Course and Exam $125
  • Sailing Endorsement Exam Free
  • Medical Exam and Drug Screening $126
  • USCG Application Fee $145
  • TOTAL: $1,765.70

While I was at Flagship I took the quick FCC Element 1 class and exam for $40 to earn a Marine Radio Operator Permit.  This is required any time you're sailing to another country or using the SSB marine frequencies.

Oh, one more thing - I've become the Vice Commodore and Race Captain for the Small Yacht Sailing Club of Oregon (SYSCO).  It's the group that organizes most of the keel-boat regattas we've participated in.  I'm sure I'll be writing more about this experience going forward, for now I'll say it means we're flying the SYSCO pennant with the red Vice Commodore flag on our starboard spreader.
