Running out of fuel twice in one day

Today was.. eventful :oops:

New boat to me, planning on doing a big refit this winter. I went over it before I first launched it and decided that whilst lots of things had been bodged by previous owners, nothing was dangerous (apart from the chinaspacher heater which I disconnected).

One thing I did do was buy a Lewmar Epsilon (Rocna clone) anchor to replace the silly bruce thing on it. Very glad I did that..

So having been out on it numerous over the past few weeks, decided on a solo trip to Clovelly (about 10nm) to lounge around in the sun for the day as my partner was off doing horsey things.

I've taken a few cans of diesel out to it, but the seller told me it had a full tank of diesel in it on the sea trial, whilst tapping on the 'fuel' gauge. So on the basis I hadn't been very far and the gauge still showed plenty in the tank, I wasn't too worried.

The 'fuel' gauge on the left, and what the seller told me was the water tank gauge on the right.

You can already guess what happened, turns out the one helpfully labelled 'FUEL' is actually the water tank gauge. And I've perhaps used it more than I thought...

I started getting a bit concerned on the way back after a lovely day when I thought I heard the engine momentarily stutter a few times, and in my head the cogs started to turn and I realised the diesel tank was in fact nearly empty.

Decided to keep going fast for as long as possible on the basis that the pickup is near the back of the tank and a bow up attitude would probably help. Made it to within 30 metres of my mooring buoy and then the engine cut out :(
Now I was panicking because the tide was ripping through at 4 knots or so, and I was 60m or so away from crashing into numerous other moored boats. Thought about dropping the anchor immediately but I realised I still had some steering so thought I would try and glide onto my mooring. I did that quite successfully but failed to get hold of mooring line (couldn't hold on with tide to slow the boat down). Managed to drop my boat hook in the process (more on that later).

Now realise I need to dump the anchor pronto. In the rush to switch the windlass breaker on somehow break my little toe. Ignore the pain. Anchor bites immediately and the jolt nearly throws me overboard. I stop about 10 foot in front of another boat and neatly in the middle between two others. Ok now I can breathe a bit. Couldn't let out very much chain or I'd have hit the boat behind.

By some miracle see my boat hook about to come floating past. Run to front of boat and dangle off the bow and manage to grab it. Ok things are now looking up.

Wave at some jet skiers for help. Curse the fact the horn is broken. Manage to get their attention and they very expertly pull me the 50 foot back to my mooring buoy. Phew. Take the dinghy back in extreme pain trying not to be swept out to sea whilst cursing at the previous owners of my boat.
Lessons learnt:
1) never rely on a gauge that you haven't checked it's function
2) always have a decent anchor ready to deploy at a moments notice
3) a little auxiliary outboard would have been useless given how fast the tide was ripping through and how quickly things happened
4) Always have a spare boathook on board
5) Always wear your lifejacket when doing any manoeuvring - I was very glad I had it on as nearly fell in multiple times.
6) Small 'bodges' that you think are harmless (like using a wrongly labelled gauge for a water tank) can have serious connotations.

Main take away is that your anchor is almost certainly the most important thing you have on board.

I can't wait to completely rewire the boat this winter. I will feel so much more confident knowing all the bodgery is gone.

In better news it was a glorious day to be at anchor.

p.s. the above was actually the second fuel incident I had today. The first was when I tried to start the dinghy outboard in the morning and after 10 minutes realised I must have forgotten to close the vent cap and the fuel drained out when it was laid down. Had to drive to petrol station to get some and then it started first pull.

Rule No 1.
Fuel in the tank !
Rule 2. See above.
It is reckoned that the average non specific gender person can cope with 2 or three things when "things" start to go wrong.
When the Wx is starting to to look decidely "iffy", white horses and or fog on the horizon, oil pressures or Temps are not where they should be, funny noises that were not there when you left or "crew members in desperate need to be on dry land.
The last thing you need to be doing is tapping the fuel gauge in the vain hope it will spring into the FULL position and coping with other things that should more urgently need your attention. :unsure:
Rule 3.
Always disconect your shorepower before departure.
 
I am sure running out of fuel is a rite of passage for all boat ouwners.

Ours was the OB motor on a wild and lumpy day had been used a lot as we had given up trying to sail and were heading back to the harbour. Neither of us appreciated how much it had been used until it stopped 100 metres out from the harbour entrance when it stopped. The anchor was deployed VERY quickly (entirely manual anchor on a small boat) while we re fuelled the motor.

After that we ALWAYS checked fuel level before approaching the harbour.

We too are in the process of sorting out a new boat and rectifying the previous owners bodges which included a chinaspacher heater as well.
 
It does look like a previous owner has replaced original gauges with inappropriately labelled gauges.
I never fully trust fuel and water gauges on boats.

I always wear a life jacket when under way , not just when manoeuvring as situation could develop as described.

Are chinaspacher heaters considered to be a bodge?
 
On one of our “cruises in company”, a large and very new Beneteau suffered a double engine stop just outside the harbour entrance.

Both fuel gauges showed 25% remaining, well above the red section.

Both tanks were actually empty.

Going on posts on these forums the heaters themselves seem ok but it is all the bits attached to them that are rubbish such as fuel hose, exhaust pipe, silencer, etc.

My problem was more with the cowboy who installed it, rather than the heater itself.

How anyone can look at this and be pleased with their work blows my mind.
It appears they found the pieces of wood that hold the diesel tank in place on the bonfire pile, already partially combusted.

No…you are just hoping that the burning happened before the wood was installed on the boat
 
Yep, ran out of fuel on the delivery run of my new to me Mobo with 25% still showing on the dial. Drifting back into the St Albans race so not funny. One of the couple of times I've been very pleased to see Seastart

That does prove fuel gauges on boats are not to be trusted.
In the case of the nearly new boat the calibration of the gauges was presumably part of the commissioning process obviously not done properly.

They can be trusted if you know they have been calibrated correctly.

Mine are a bit variable at the upper end of the scale, but the amounts required to fill the tanks from 1/3 remaining seem quite close to the manufacturers specification of the tank size.

Also … if it says 1/3 remaining, then the gauge doesn’t move for the next 2 hours, it could be that the fuel consumption has magically improved. Alternatively …
 
I don't let mine go below the start of the red sector and that's worked for me .
But guess no two boats and no two fuel senders are the same.
 
We have cocked sight glasses ( actually plastic tubes ) every morning doing my ER roads I take a peek .
To see the real levels .The gauges , a L + R are pessimistic, but it’s better that way .How ever nice to see the level by mk 1 eye ball .

Having said this I have set off first trip of the season with main fuel cocks closed .Got just outside the marina before as you say ( anchor ready ) dropping it as each engine conked out .

A size 10 ring spanner to bleed the air , a bit of a grumbled turn over and 10 mins later we were off .Open tank cocks this time .

My fuel gauge is a long wooden dowel. One day I was checking the tank with said dowel and was just saying to a new crew member how not to trust fuel gauges on boats and how the stick was the only reliable method, when the dowel snapped... 🙄

My personal version is

Rule No 1.
Fill the tank !
Rule 2. See above.

Apart from probably a high cost the first time, it won't cost more to keep the tank full. The engine certainly doesn't change the consumption rate and you mitigate the condensation issue by a partially filled tank.
 
I am nearing the end of the second season with our boat, Aquador 32. As above, it takes a while to suss accuracy or otherwise of the fuel gauge. I now know that there is more fuel in the tank than the gauge suggests - which to me is the right way round. As supposed to you guys above running our at 25% full. When mine reaches the red I now know that I have around 100l left, or 2 1/2 hours running at cruising speed. Took a bit of sussing though as nominally the tank holds 675 litres, but I'm not convinced, I reckon that it's nearer 500. But unless you fill it from empty how can you be sure. Also, no way to dip the tank and almost impossible to measure for volume - shape and location.
I reckon that I can do about 150 miles at her sweet spot cruising speed of 14kts. She is a heavy boat, 6t, and semi-D.
