Re: Trawler - Single Engine vs Twins

I remember have a hard discussion time ago on another forum about same question.
My conclusion about that.. if you have money, get with a double engine.. more reliable than have a hybrid like a single screw and a "get home" engine (??).
If you are in a budget, get the single screw and be more cautions about maintenance.
My personal preference is go with 2 engine and run both at low rpm (I'm not a big fan of run one and let the other off...) but off course the gas consumption is gonna be higher but you're gonna get better speed.

No, twins are less reliable. Twice as much chance for a breakdown.

Although it's counterintuitive I agree. If you have twins a problem with either motor will keep you tied to the dock.

You miss my point.. I can agree twice chance of breakdown but same spare parts... Modern engines with adequate maintenance are less prone to have problems.
In fact with adequate maintenance you can run for years.. mostly time problems with engines is due lack of use and adequate maintenance rather than excesive use or use off the envelope...

Re: Trawler - Single Engine vs Twins

Everyone has an opinion. Driving a trawler near the dock is not like your sailboat. The windage is huge. Either get twins with a bow thruster, or get a single with a bow thruster and a stern thruster.

You will save fuel with a single. I've serviced one engine while the Admiral drove the boat with the other. I also drive with just one engine running on a twin - the autopilot don't care.

Re: Trawler - Single Engine vs Twins

climber49, it would seem that the general consensus from a bunch of very experience cruisers here is that you would be quite well served with a single diesel and a bow thruster if you need it.

The reason I say if you need it is because you may not be docking in a slip that is tight and requires high maneuverability. However the biggest factor is the vessel itself. The vast majority of all recreational "trawlers" out there (Albins, Grand Banks, Defevers, etc.) are either (1) semi displacement hulls; or (2) light and of high windage, flybridges, oxygen tents, etc.

If however you were to acquire a very heavy, deep draft, low windage vessel with a long keel and a large rudder (perhaps modified with a fish tail) then I seriously doubt you would need a bow thruster in 99% of all conditions you find yourself in.

In any case, when you buy your boat, but before you commit to spending thousands on any thrusters, invest in one weekend of training with a very experienced skipper who is familiar with handling your type of vessel.

From first hand knowledge - when I bought my monster boat I was intimidated as hell for months. I practiced docking a hundred times and constantly screwed up. Then one weekend I asked a retired freighter captain to teach me while taking me to the commercial fuel dock. It was wonderful what that one weekend did to my self-confidence and abilities!

Good luck.
