For nearly 3 years we lived aboard and cruised a 53' Selene, Celebrate,
with twin Cummins 220s. We logged daily. Here are the figures over the
entire span:
Total Miles (nm): 14,139 Avg Speed: 8.02 kts
Total Hours: 1,762 Avg (n)MPG: 1.56
Total Fuel Used: 9,039 Avg GPH:
5.13
We were satisfied with the performance and economy we experienced. Properly
maintained twins, run efficiently, are a match in performance for a large
single. They are a perfect spare parts inventory and a powerful 'get home'
is included by definition. When the cost of adding thrusters and a wing
engine to a single engine vessel are considered, the capital investment is
not that much different either.
Having said that, as they say, "Your mileage may vary . . . ."

Subject: T&T:
What's the old argument? If it refers to the fact that two engines use more
fuel than one engine, that "old argument" is still true. You just can't beat
the efficiency of a larger versus two smaller props.
