Dark, I know mechanical injection and the older diesels are proven, and fairly bullet proof but I don't agree that the new computer controlled engines are more prone to failure. Common rail and the associated electronics have been around quite awhile now, and I rarely if ever hear about the concerns you are noting. Granted, stuff happens, but these new common rail engines are proven workhorses.

Now pods, especially the first gen up to around 2013 or so are a different animal and these did have computer related issues causing the loss of propulsion but that is a subject not related to trawlers. How do I know..first hand experience and talking to other owners.

He does this in company with another boat, something you might want to consider. (I'm leaving about May 15th.)
...and, yes, I have done it before.
A very good read indeed.

Not belts and hoses. Not fuel problems. Not prop, shaft or rudder damage due to striking something. I'm interested solely in breakdowns due to mechanical problems.

And would the break downs have been repairable at sea? Provided you had the spares, tools and skills.

Many have made the point that maintenance, preparation and seamanship are more important than the number of engines. I agree with that but I want to hear from those who got home because they had more than one engine.



Yes, I am a proponent of twins over single power. This is not due to many engine failures, though I have had my share. I have never lost a vacation due to a mechanical failure, though I know several single owners who have spent the greater portion of theirs in a shipyard, far from home.

To specifically respond to PBs post

1 Lost a starter a day from home, at Lasqueti Island. Due to strong headwinds, headed to Secret Cove instead of home to Vancouver, took the dead started home on the ferry, returned the following weekend with it rebuilt.

2 Lost an oil cooler at Sarah Point (Desolation Sound) at the beginning of vacation. The low oil pressure horn was the first indication of a problem. a hole, 1/4" diameter, had opened through the aluminum case, allowing a stream of oil to drain into the pan beneath the engine. Once I found where it was going, I put a bucket to catch the stream and used that engine only when needed for docking. Returning the oil to the engine worked well until I returned home 3 weeks later. Got the oil cooler repaired and it still holds on.

3 On checking the oil, discovered a milkshake in the sump. Took it in on the other engine, got the source of the water identified (raw water pump) and repaired, several oil changes to see if the engine would still run, and set out again on both, only to have that one bend a valve in mid Georgia Straight, and require a full rebuild. I was able to postpone that repair from June to September, so as to save my summer vacation, which was then done at 6.5 knots on one engine instead of at 8 knots on two.

Added benefit, I learned to dock in current and wind on the Starboard engine only (no thrusters).

As I said, any one can fail at any time beyond the abilities or parts carried onboard.

Therefore, as long as the inconvenience of breaking down where you dont want to be and the costs involved dont bother you, no big deal.

It's not quite as simple as that when cruising in isolated areas where there is no towing service, few safe harbors, and very little boat traffic.

It can be more than an inconvenience when you have no form of propulsion and the wind is pushing you towards breaking surf on the rocks.

With all the cruise ships and ferries, isn't it practical to communicate with them to forward a "help" request to an entity that could provide help?

That is exactly what happens when there is a vessel near the site of another vessel in trouble. This thread isn't about what happens when a potential rescuer is nearby, rather is about your self reliance when in an area of danger, with no help at hand.

My experience with RCMSAR (active crew of unit 25, Saltspring Island) shows me that vessels of opportunity. including ferries and cruise ships, are often first on scene, and always communicate with JRCC (Rescue coordination) who then task the most appropriate available resources to the rescue.
Those resources are spread very thinly once you travel beyond the highly populated areas. In the Gulf Islands we have RCMSAR and Coast Guard vessels with a response time average of around 1/2 hour, plus many vessels of opportunity. On the Central Coast, not so good, as the distance between assets can be from few to many hours.

I'd add that you also shouldn't do any trans-Atlantic or Pacific flights with two engine ETOPS aircraft

Neither of my twins nor the generator quit on my round trip to Alaska. If your engine is well maintained you should be fine. Of course I carried plenty of spare parts which ensured nothing would fail.

We have had our single engine vessel in Southeast Alaska for the past 20 years. We travel all over Southeast putting on average 300 hours each summer. Iím religious about oil and fuel filter changes as well as oil changes. I believe with preventative maintenance and spares aboard you should be just fine. If you are in need of a mechanic one can be found in the cities and towns along the way. As in a previous post the majority of boats in Southeast Alaska are singles.
