Annual Service

As the clocks go back and the nights draw in, it's time to give Patience her annual service and get her ready for the winter. As well as the usual oil changes (engine and gearbox), filter changes (engine oil and fuel), checking and adjusting the tappets, checking the anti-freeze concentration, the electrolyte levels in the batteries and draining down the domestic water system, there were a couple of engine parts that needed replacing this time.
We had noticed a slight leak in the flexible high pressure oil pipe that runs from one side of the main cylinder block to the other (see photos). 
Original flexible oil crossover pipe going into port side of engine block
Flexible pipe connected to the starboard side of the engine below the fuel filter
The first photo shows one end of the pipe on the port side just below the gearbox oil cooler and the second photo shows the other end where it connects to the block below the fuel filter. Although the leak (where the flexible hose is swaged to the end fitting) wasn't yet serious, it is an indicator of a potential weakness that could be serious if it failed suddenly and led to a loss of engine oil pressure.

I discussed the problem with the very helpful people at Calcutt Boats, who are specialists in BMC marine diesels.  They recommended replacing it with a steel pipe pre-formed to the correct shape, which they stock in their chandlery as part number BM2M56598.  It was a surprisingly easy job to remove the old flexible pipe and replace it with the new one, which fitted round all the engine auxiliaries. This should last as long as the rest of the engine.

While removing the rocker box cover to check the tappets, I also took the opportunity of replacing the rocker box gasket, which had lost its flexibility and was showing signs of leaking.  The only task that remains to be done on the engine is cleaning out the heater plug ports (recommended every 600 hours running) but time was getting on so I left that for another day!

Day Trip to Foxton

It's been a busy summer but there's a nip in the air, there are logs on the stove and we decided on a two day trip to Foxton Locks as a farewell to the 2016 boating season. Together with our wives we set off for Welford amid some heavy showers and set off up the arm under cloud and in rain. Not a promising start.
We moored up at the junction for our picnic lunch, contemplating whether to go back or go on. Fortunately the weather cleared and the canal opened up to the usual splendid views across fields and plains and the Laughton hills before the approach to Foxton Locks. I plan to stroll the Laughton Hills at some point, with convenient moorings just south of Foxton, but that will have to wait for another day.
This was a relaxed and uneventful trip to Foxton, mooring near the turning junction above the top lock and an evening stroll to the popular Foxton Locks Inn, always wary of the water surrounding us in the dark.

Next morning dawned bright and clear but, wary of the weather forecast of afternoon rain we headed back to Welford for another picnic lunch (and a few minutes of painting) before reaching home by mid afternoon.
Soon we'll need to do some winterising, patch painting, rust treatment and general maintenance before it gets too cold to work comfortably. Then Patience will be tucked up for the winter.

South Oxford canal, in summary

So we took 5 days to get to Lower Heyford, rather than Oxford, and 4 days to get back.  We went 61.5 miles and through 43 locks - each way.
We moored at Lower Heyford for the weekend rather than go to Oxford because Heyford is a pleasant mooring, whereas Oxford can be rather busy, and by cutting out out the 14 miles and 9 locks each way to Oxford we managed to replace it with a pleasant five mile walk and a 15 minute train journey.
Heyford has a very convenient station, water and rubbish facilities, a handy shop, 3 nearby pubs, a house and garden to gawp at, 2 pleasant churches, good towpath walks and a very fine tithe barn.
We enjoyed the Oxford Canal southern branch very much and would recommend it for its scenery, kingfishers, general interest and good waterside pubs. Its many locks, though single width, have the virtue of a stepping area just beyond the gate so that the boat can stop, the gate closes behind it and the crew member working the locks can step aboard without needing to moor up. Handy.

It should be added here that our engine bilges are usually wet - mostly just water leaking in from rain, as the gutter around the trap door clogs up with leaves and the outlets too. Occasionally there is a sign of anti-freeze and once even a hint of diesel. None of these has ever been a significant problem, but something in the bilges may indicate a problem now or in the future.
John regularly checks all this using a shaving mirror to magnify or a mirror-with-light on a stick to access hard to reach hoses and connections. Given that Patience may charge along for up to 8 hours non-stop, heat will expand joints and vibration will loosen connections. Age and hot fluids will perish rubber too, so it is always valuable to inspect, tighten and replace if necessary as part of daily maintenance.

 So at end of September 2016 here, in yellow, are the canals and rivers where we have taken Patience.
Gradually the yellow lines showing our travels are extending from the Ouse and its tributaries to The Grand Union and beyond.  Zoom in online to see the map more clearly.

Where next?

From Oxford 4. Braunston to Welford

Thursday 22nd September
Off at 8.45 amid showers and through Braunston locks (double width, what a change!) alongside a group of Dutch people enjoying our canals.
Part way up we're interrupted by a cranky old boy with full grey beard and yellow oilskins who seems to be shouting at his boat as it careers across the pound ahead of us and turns to 90 degrees. I go up and try to help whereupon it seems he is shouting at his unfortunate, disabled, wife who is within, while his boat is partly grounded in the low water of the pound and swinging around from the stern as he tries to gain control. Opening the lock for him raises the level, eases his grounding and at last enables him to get in to the lock and away.
We too get in and away, charging on to Norton Junction and to the bottom lock of the Watford Flight by lunchtime. As usual there is a queue, though not as long as last time (only 2 hours!), and we begin to think we could regain our home mooring at Welford before night fall.
We are out of the top lock (there are 7, gaining 16 metres) at 3pm and with the estimate from the lock keeper that it's just 4 hours to Welford we consider being home tonight instead of tomorrow as we'd believed.
It's a beautiful day now, bright low sun through trees highlighting furrows in freshly ploughed fields, and we are going at a good pace (John calculates just under 3mph and believes we are going a bit too fast) so at this rate we can make it in time - if we want to.

In my own mind I set a target of arriving at the Welford junction by 7pm. Any later I thought would be too dark and it would be preferable to moor up just before the junction and rest up with the food and drink we had on board. With the temperature gauge warm but not quite overheating, and with sunset at 7.01 pm, we arrive at 7.07 and I make the decision to go for our marina.

Down the dark Arm we went, surprised to be crossed by another boat heading back to the main canal, cautious but confident in gathering gloom, and then assisted by our trusty hand-held spotlight, we approached the pound. The spotlight illuminates the narrow entrance and we are through without a bump. John leaps off, dashes to the lock, opens it and I glide in effortlessly in near total darkness.  What little light remains in the sky helps make it lighter than down the tree-lined Arm.
In minutes we are through and at the marina, helped now by the electric lights from the Basin. We moor up at 7.45. It is late September. It is very dark. We are home.

I found it really quite exciting (narrow boating isn't usually exciting, is it?!) and certainly memorable, if not entirely sensible. Of course we had lights - spotlight, headlight and navigation lights -, plus experience and familiarity with this stretch, so it was less tricky than, say, a long tunnel. CRT don't recommend it (please don't try this at home, youngsters).
But what fun!

21 miles, 14 locks, 11 hours

From Oxford 3. Fenny Compton to Braunston

Wednesday 21st September
Passing the water buffalo again at Adkins Holt Farm ... noting long term moorings up The Engine Arm off the Napton Flight, we push on with the aim of arriving in good time at Braunston. Being a busy place we know moorings can be tricky to find.
We arrive at the Braunston Turn at 5pm ...

... and struggle to find anywhere not dedicated to long term moorings, near a water tap or a bend or otherwise inappropriate. Finally we are uncomfortably near a busy road bridge and a dog poo container overflowing with people's rubbish - but it'll have to do. We can't find anywhere nearby to deposit our own rubbish (come on, Braunston, it's not hard ...) so we hang on to it.
Evening meal at The Globe on Braunston High Street. Not as posh as The Admiral but perfectly adequate in the dining room.
17 miles, 9 locks

From Oxford 2. Banbury to Fenny Compton

Tuesday 20th September
Overcast  at first, dull but thankfully no rain, we set off from Banbury in good time and head north, reflecting on the very fine waterside, newly pedestrianised old centre - but the tortuous back street route from one to the other. Perhaps they ran out of money .... though that doesn't explain the lack of life in the evening in the centre. Has the huge shopping centre, so busy during the day, sucked the night life out of Banbury?
On and up, under drawbridges, past gardens that border the canal, and now with the sun on our backs, yesterday's dampness squeezed out of us.
We stop in at Cropredy marina for a pump-out which appears to confirm that we can go longer than a fortnight without needing to pump out, though without a gauge to measure accurately we are not much further forward. Cropredy is a huge posh marina, but we push on, up the old Oxford with its quaint lock-keepers' cottages ....

And before we know it we are at Fenny Compton, at "the summit" so from tomorrow we start heading downhill.
Fenny Compton is packed with boats and we're lucky to find a place 1/4 mile from the Wharf Inn. There are more than  50 boats lined up here and the pub is very busy, but food is good and very well priced.
10.5 miles 12 locks

From Oxford 1. Heyford to Banbury

Up early knowing we have places to go and we are at the water point at 8.45 - to find a) someone already there b) there is only the one tap c) it is the slowest tap on the network d) if we do ever get to it and fill up we'll have to reverse through a bridge and do a 3-point reverse into the wharf to turn round and face in the right direction. Oh yes, and it's started to rain ....

So we don't actually set off until 10.30 and we make a note to tell CRT they've got a useless tap.
And it's raining .... so my memories of the rest of the day are just increasingly damp, very very damp.

We arrive in Banbury at 6.15 and it hasn't stopped raining, so changing into dry gear and hanging up the damp clothes is the first priority. Standing outside at the tiller for 8 hours of constant rain isn't so much fun.
We are moored right next to Tooley's Historic Boatyard.
Look closely and you will see that they offer "The ISIS school of boat handling." Is that the terrorist's alternative to the SAS and Special Boat Service?

At last with umbrellas up we head for The Old Reindeer, Banbury's oldest pub and quite atmospheric. We are served by an enthusiastic young man and a charming blonde ex-ballet dancer (see her pirouette as she changes direction with our meals!) and she also shows me around The Globe, the old panelled room where, it is said, Oliver Cromwell planned his campaigns.
Back at the boat, having negotiated the back streets of Banbury, we light the fire and try to dry our kit.
And still it rains ....

12.5 miles, 7 locks
