I seriously doubt that it would ever be practical in most recreational
trawlers.  The trouble is that most trawlers have grossly oversized engines,
such that they typically cruise at about 15-20 percent power output.  If you
had a dual fuel NG/diesel engine, then you would be running 100 percent
diesel at those speeds.  If you were running an engine at the top end of its
power band, though; then the NG could be very practical in a dual fuel trawler.

Sorry if this has been mentioned before but I just picked up on this thread.
UBC, released a report last year describing an engine that uses a
combination of diesel and propane.  Sounded like this was something that had
been around for a while but recently became more feasable because of the use
of computers built into the engine. That's all I can recall of the article
and considering I'm working from memory, there's only a fair to middle'n
chance I got it right.
