Back from Hiatus

Judging by the comments, emails and in-person needling at parties and social events, it would seem that people do in fact read my blog. I’m flattered and encouraged, and I apologize for the quiet stretch; it’s been about a month and a half since my last update, and that one wasn’t of much interest anyway. This posting should mark the end of that dry spell and a return to a semi-regular posting schedule.

So, uh… where have I been?


View March 26th 2010 in a larger map

I’m anchored about 300m west of Kitsilano Beach, where I’ve been since February 1st.  There are no regular police patrols to worry about, the marine traffic is low, the people are friendly and the neighborhood is pleasant, if a bit homogenized for my tastes, and perhaps a bit remote from most of my regular haunts. The scenery is good, and I peacefully weathered the collective insanity that was the Vancouver 2010 Olympic Games without incident. I’ve technically been “legal” to return to False Creek for just over two months now, but in all honesty I’ve been quite enjoying the change of scenery; all things considered, living on Kits Beach is quite lovely and I haven’t felt any strong drive to return to False Creek. I will very likely return to “my spot” near the Cambie Bridge soon, but I am not in any particular rush.

I was told that anchoring out here would get very unpleasant if the weather turned foul, but in reality the only time it’s bad is when the wind comes from the west – there’s reasonable shelter from the north, east and south, but the open ocean is to the west, so even a light breeze can build up a wave system.  Rowing back home to Tie Fighter can be somewhat exciting when the wind is blowing hard and the waves are 50cm or more and breaking onto the beach!  The first time I tried to row home during a westerly blow, as soon as I pushed off the shore the rowboat was pushed sideways by a wave, where another breaking wave caught her and nearly dumped me completely over, right back onto the beach.  Two or three more waves broke into the dinghy in that row home, and by the time I reached Tie Fighter there was 15cm or so of water around my feet.  Since then I’ve been making a point of using a massive yellow drybag backpack that my friend JP gave me – whenever the weather report looks dubious I replace my usual Chrome cycling bag with the drybag.  I’m certain this practice has saved my laptop from getting wet at least twice.

stuff on my table
completely unrelated: random stuff on my table. whatever, blogs are better with pictures.

Gathering potable water was a big question for a while – during the Olympics, my usual water fill-up spot, just under the Granville Bridge, was blocked by a barge holding a three-story restaurant.  I never did figure out exactly what the point of it was, but the last time I sailed past there were people seated at a table in the window, being served lunch by a waitress; all three waved at me as I went by.  I have been living out of a set of five 4l water jugs for… oh, it must be about three months now.  I fill them up once a week or so; I used to use the faucet on the side of the government building near the Cambie Bridge, but now I’ve been using one on the side of the Watermark Restaurant on Kits Beach.  The restaurant has “security” faucets, which require a special tool to open an access panel and the same tool to turn the water on and off; neither the panel nor the faucet are any match for my trusty Leatherman tool. Before I figured out the security panels, I had been skulking around in the alleys of Kitsilano looking for an unprotected faucet and feeling somewhat scandalous.

Honestly though, the two biggest problems about living on Kits Beach are both related to the beach itself.  For one, there’s really no place to lock my dinghy, so every time I go ashore I have to drag the dinghy bodily up over the tideline.  At low tide, the tideline is a 150m slog uphill in wet sand, dragging a 90kg rowboat, a backpack and a bicycle – some days I have to do this three or four times, and almost every time it’s just a warmup for a long, fast bikeride.  I figure this makes up for not renewing my gym membership.

Kits Beach in the summer

If I leave the dinghy overnight on the beach overnight in good weather, I have to worry about drunken idiots trying to steal it for a joyride.  They usually abandon their mission after they realize the oars are padlocked together and to the boat, but twice now the dinghy has been dragged below the tideline before being abandoned.  If I had been another few hours before returning, the dinghy would most likely have washed away, leaving me with a choice of calling in a couch-favour from a friend, a cold, wet sleep on the beach, or a very cold swim home. This won’t be as big a problem in the summer – in fact I’m considering the idea of swimming to and from the boat just for fun.

In the daytime the dinghy faces a completely different problem; several times now I’ve returned to the beach on warm, sunny afternoons to find children playing in my dinghy. This doesn’t bother me in the slightest in principle, but for the fact that the universal game to play with a boat found on a beach appears to be “See How Much Sand We Can Pile Into The Rowboat“, followed closely by “Appropriate The Bailing Bucket As A Beach Toy, And Lose/Bury/Keep It“. I don’t remember these games from when I was a kid, but just for your own reference my dinghy is *very* difficult to effectively clean sand out of, and making a bailing bucket out of an old laundry detergent container has the important prerequisite of first owning laundry detergent.  If you are the sort of person who owns laundry detergent, I would be much obliged if you would save the jug for me.

The second problem is the sand itself – it gets in everything!  Regardless of how much is in the dinghy, walking across the wet beach my shoes are completely coated in the stuff.  I track sand into Tie Fighter on my shoes, then from the salon into the bedroom on my socks, then into my bed on my feet.  I have sand in my bed.  Do you know what it’s like to have sand in your bed?  In March?

thermostats and tea
boiling water serving two purposes - making tea and testing Yanmar engine thermostats

The engine situation hasn’t changed even a little bit.  There are three bottles of C-L-R sitting on my navigation table, and one of these afternoons (perhaps tomorrow, actually) I should take the time to run it through the engine block just to see how it fares. I will likely need to use several plastic buckets and re-route one or more of the engine water pumps to get the C-L-R into the appropriate engine chambers. It could get messy.

I did take some time to try to diagnose the problem a little further, and I’m starting to think that at least part of the problem was just that the thermostats had corroded into a partly-open state.  I’ve got a new set of thermostats in there now, but given that they’re still in raw water I suspect that I’ll have to replace them yet again before I can call the engine “maintained”.  I still have to convert Maude back to antifreeze cooling and get the electronics all hooked up properly, so that I can have alarms and warning buzzers and gauges on the engine again. Soon, Maude, soon.

Anyhow. Hiatus off. More regular updates to come. I promise.

A Quick One

Well, I made it out of False Creek.  I can’t exactly say I made it unscathed, as I managed to somehow burn out (part of) my exhaust system again – but at least I’m out, and out of the immediate danger of being towed away and impounded by the VPD.  Instead, now I am broken down at anchor about 300m due west of the Maritime Museum, bobbing around in the wake of every ship that enters or leaves False Creek, and potentially in danger should the weather turn foul.  Tomorrow I will be picking up a few replacement parts that will help get me up and running again and over to a slightly more comfortable spot.

hoooooovercraft
completely unrelated: Friday morning I was woken up by yet *another* hovercraft. how awesome is this photo!?

I think I actually know what’s going on now.  At some point, X minutes after pushing the engine hard, the cooling water ceases to flow into the exhaust and the superheated exhaust burns a hole in the tubes.  There are a pair of thermostats that redirect the water flow from the exhaust manifold and into the main engine block once they heat up, though the water should then flow into the exhaust manifold and out the exhaust.  I now suspect that the engine block has become fouled with calcium scale, and now water no longer flows through it.  Fixing this will likely require a heavy-duty descaling solution, or perhaps straight-up muriatic acid.  It’s a touchy procedure, but there is hope – I may have finally sorted out a way to barter myself some time with a proper diesel mechanic!

More soon.  I simply have too much work to do to write proper, long blog posts right now.

UPDATE: Swapped in an edited version of the hovercraft shot, with levels and curves tweaked by Jason Sims.  Nice one!

Stress

I started to write a blog post on Friday morning, but by Saturday evening the still-open browser window – the blog editor page with just the word “Stress” written in the title box – had become its own succinct review of the events of those two days.  I won’t bore you with the details, but the main point is that after some fast talking, the VPD granted me another couple of days to get my engine going.  I spent most of the weekend working on her, and as of now I am reasonably confident (though knocking wood) that she is working well enough to get me the heck out of Dodge.

A quick highlight reel – in the past three days, I:

  • bicycled over forty kilometers and rowed over eight kilometers in total,
  • borrowed a truck and drove to Bellingham and back for engine parts,
  • had my oil filter spring a leak, leaving me with a couple of liters of used engine oil in my bilge,
  • spent over $700 on a new exhaust system, and assembled and installed it,
  • ate six cans of sardines and probably over a pound of sliced ham,
  • drank most of a bottle of Sailor Jerry, and
  • went out dancing.  Twice.

Tomorrow morning I try once more to escape the Creek.  My first destination will be Kitsilano.

The Bits In Question

It’s now been about twenty four hours since “the incident”, and the VPD still haven’t shown up.  I’m not much looking forward to their visit; it could really only go one of two ways, and those ways depend entirely on who the attending officers are.  I figure they will either let me stay – though they may be angry and/or aggressive – or they will tow me out.

The problem with being towed out is that I cannot safely anchor out in English Bay in February weather without an engine – if I drag anchor, I could end up on the rocks, or worse.  They can’t – or at least, they shouldn’t – put me into a potentially dangerous situation.  That leaves one option: they could choose to tow me to the VPD docks and impound my boat.  That would *really* put a damper on my adventures!

Anyhow.  I found the part I need.  Actually that was easy, as I had already sourced and purchased the part a few weeks ago.  Unfortunately, getting another replacement wasn’t so easy, as there apparently isn’t a single water trap in Canada at this time.  With some calling around and favours called in I managed to track down a water trap at a marine supply house in Seattle, though due to license agreements they cannot sell it to me in Canada.  They did however suggest a shop in Bellingham that they could sell to, who could subsequently sell it to me, and so by way of Sweden to Seattle to Bellingham to FedEx to Vancouver – at significant expense – the part should arrive on Monday.

exhaust system
all the bits I need to replace

The real faulty part, the one that I am 95% sure caused all these problems in the first place, is available in Vancouver.  According to the internet, the raw water injector elbow apparently only lasts about five years before rusting out and clogging up – honestly, I should have predicted this, it would have saved me a lot of time and money.  The injector elbow is attached to the engine block with a… I don’t know what it’s called, an attacher elbow thing. That thing was seriously rusted, though when I last removed it to check it it seemed fine on the inside, and the guys at the marine store said that they last an awfully long time, so I wasn’t worried.  Still, when I went to pull the injector elbow off today, the bit connecting the two snapped off in my hands.  Not exactly the kind of behavior you expect from an ostensibly solid steel fitting!

The results of running the engine without exhaust cooling are evident in the photo; a big hole burned in the water trap, the plastic elbows melted, and the bit of flexible exhaust hosing is now somewhat suspect.  I’ll likely replace the exhaust hose at the same time, probably picking up a few new stainless-steel hose clamps as well.  The funny thing about hose clamps is that about 80% of the time they say ‘stainless steel’ on them but the little screw holding them together isn’t actually stainless, so after about a year you come back to find the band is still nice and shiny while the screw is a featureless lump of rust.

Anyhow.  This isn’t even close to what I’m supposed to be working on right now.  I have a big webserver rollout with a due-date of Monday, which means I’ll likely be working through the weekend.  Back to the grind…

Well, That Could Have Gone Better.

Ouch.

This morning I awoke to a gorgeous, sunny day, an obvious sign that my move out of False Creek would go smoothly.  Of course, I neglected to check on the phase of the moon or something and it all went horribly pear shaped – I am currently still at anchor in False Creek, about 500m west of my previous anchorage.  I’ve been sitting around doing dayjob work and waiting for the VPD to show up so I can tell them my sob story and pray they don’t issue me a fine or tow me.

This morning I cooked a big breakfast, checked in on work stuff, and prepared Tie Fighter for the grand exit.  I fired up the engines – she started (almost) right away!  I pulled the anchor; no small task, with months of False Creek grime and growth along the full length of the rode, and noticeably heavier due to the addition of a thick steel cable that I dragged up from the bottom also.  The ocean floor of False Creek has a legacy of a hundred years of industrial garbage.

I motored away from my anchorage, a bit nervous, and made it about 200m west before I heard a strange ‘clunk’ and the engine started making a new and different noise – nothing huge, but a perceivable shift, and that’s never a good thing.  I went down and checked out the engine compartment, and I could hear a bit of a noise but couldn’t see anything out of place.  I later discovered that the secondary water pump – which wasn’t hooked up, but which I had bolted loosely to the engine “just to get it out of the way” – had shaken loose of its mounts and was resting against the beltwheel of the primary water pump, grinding into the bronze housing of the pump.

I went back up to the cockpit and throttled up, and things went smoothly for about five minutes – I could almost see the Granville Bridge, and I figured I could dock there and sort any further problems out before making my way out into English Bay.  No such luck; within another minute I felt the engine power drop suddenly, and I saw smoke begin to pour into the cockpit via the engine compartment vent.  I immediately throttled down, dove below and opened the engine compartment hatch, only to be met by a cloud of black smoke.  I killed the engine and waved the smoke away looking for signs of fire, ready to jump for the fire extinguisher at the first sign of flickering yellow and orange.  Fortunately there were no flames, just thick, black smoke pouring out of the dark engine compartment.  I thought at first that perhaps I had over- or under-tightened a belt, but as I looked closer I realized that there was a gaping hole melted into the side of the brand-new water trap I had just installed, and the plastic elbows in the exhaust line had both melted beyond recognition.  $@&%!  The smoke was a combination of diesel exhaust and scorched plastic.

With no engine, floating free in the shipping lanes of False Creek, I was in a bit of a bind.  I threw out my anchor and got on my VHF radio.

“Vancouver Coast Guard Radio, Vancouver Coast Guard Radio, this is Tie Fighter, Tie Fighter, over.”

“Station calling Vancouver Coast Guard Radio, go ahead, over…”

I outlined the situation – normally the Coast Guard would recommend me contact a towing company, but given that I was about 500m from their station I thought it might be worth a try giving them a call.  About ten minutes later they showed up and offered me a tow, which I gladly accepted.  They tied the massive Coast Guard zodiac – the ‘Kitsilano 1’ – to the port side of Tie Fighter and towed me the 150m or so to the nearby anchorage, where I dropped my anchor.  I thanked them and sat down to give them all the information needed for their incident report.  They left me a copy of the report, so that I can present it to the VPD when they come knocking next.

Anyhow – the long and the short of it is that my exhaust system has been malfunctioning for a while, and now I am 95% certain the problem is in something called a “raw water injection elbow”.  The elbow is where seawater that has been used to cool the engine is injected into the exhaust system, cooling down the exhaust and ejecting the warm seawater from the boat.  These elbows apparently only last about five years, and lacking a decent record of maintenance on my engine, I have absolutely no idea when the last time mine was replaced.

End result?  I’m still in False Creek, albeit closer to the Granville Bridge.  A new water trap is about $330 (I know this well, having just bought one last week, argh), a new injector elbow is $390, the connecting bit which may need to be replaced is about $120 and the replacement exhaust elbows are about $35 each.  Instead of moving on with my great adventure, I’m now out about a thousand bucks and have a bunch of engine work ahead of me.

Someday.  SOMEDAY this engine will be stable and reliable!
