Age catches up with us. Back in 2009 when I got back from Dubai, Dad had an incident on the water. He'd inadvertently turned off one fuel tank. We have a pair of conventional mechanically injected diesels. In theory they draw from their own tank via primary filters, and they return to the same tank. There is a crossover valve which allows a small balancing flow to ensure both tanks are equalized.
If you turn off a tank, both engines will draw from the other tank via the crossover, but they return fuel to their own tanks. So with one tank isolated, the engine on that side will slowly suck fuel from the opposing tank and return it to the isolated tank. If both tanks were full, that'd push fuel out the breather as it slowly drained the tank that was still turned on. Knowing dad it probably pushed 200L of diesel into the Swan River. Regardless, at some point the tank being drawn from will empty.
That was the background. Boat on the river, both engines eventually stopped, anchor down and urgent call made. My brother did the same thing a year or so ago, but he was 5NM off the coast. I'm pretty sure I've mentioned it previously. Anyway, I talked dad through the checks over the phone, identified the issue and how to work around it. He still requested my physical presence to sort the problem out, so I drove down and hitched a lift with some bloke in a RIB to get out to the boat to sort the fuel system issues out, bleed the diesels and get it back in the pen. I asked why he didn't do it himself and he replied he didn't know how to.
My father was the man who taught me how to do this stuff. My first experience at bleeding a diesel was at age 10 after running out of fuel in a yacht with the mast down crossing under the Freo bridges. The only time in my life we'd been mechanically let down on the boat. He put the outboard on the dinghy, got out in front and dragged us through the bridges with a rope over his shoulder until we could get the mast back up and sail back to the pen.
He'd lost confidence in his ability to do the things he'd been doing all his life.
30 years ago, if I had a fortnights work to do I'd take the boat to Rottnest and sit on the mooring with my laptop and just work for a couple of weeks. Fast forward to last weekend and I'm nervous about being on my own in the boat. I've lost all the confidence I used to have about being able to just deal with any issues that might arise. I'm 18 years younger than Dad was when he had the fuel issue, but suddenly I see where he was coming from
I don't know whether or not it's because I'm now more aware of my actual limitations, whereas before I was invincible, or it's just me acknowledging all the additional risks I never bothered to look at before. I'm not sure I like it, but I suspect the older I get the worse it'll get.
