Someone should tell the Gilmore Girls that viagra is a lot cheaper
than double diesels, and probably just as effective. Anyway, to
sherrif chuckies point, my children (the next generation of spenders)
and many or their peers are moving toward greener play across the
board. Kayaking (touring), indoor rock climbing, and bike trips are
big, vacations are no longer Daytona, but New Orleans for cleanup and
culture. Many of the local water ways are making provisions for much
smaller boats, and recreation and motor restrictions are getting
tougher every day. The overindulgent will still have their big boats,
but they will pay though the nose, be subjected to more restrictions,
and their numbers will drop due to financial attrition. I don't know
that the situation will ever improve for them from this point on. Once
the big manufacturers tool down, I don't see them coming back.

I am curious. What makes you think that a 20'-25' outboard or I/O powered
boat being used for it's intended purposes is any more fuel efficient than
a
40'-50' twin diesel cruiser being used for it's intended purpose? The
truth may surprise you.
You know what was interesting to me on this whole twin engine deal I
did today?

We used less fuel (diesel) than I would have used on the Contender
doing the same kind of stuff.

On the other hand, the Contender would move a hell of a lot faster and
cruised higher than the Topaz's top end.

I think overall, the diesels would be cheaper in the long run, but you
just can't get the oommph you can with outboards. :)


Ahh, you spoiled my carefully planned setup of " justwaitafrekinminute".

The difference is the speed at which you play. Consider the differences in
a couple of boat examples:

Boat "A": 25' something with a 225 hp gas outboard or a 300 hp I/O setup.
Boat displaces about 5K-6K lbs. With a couple of people aboard plus "stuff"
what is it's fuel burn at "cruise" which is probably 32-35 kts?

Boat "B": 50' something with twin, 370hp turbodiesels. Boat displaces
38k-40k lbs. With any legal number of people aboard plus all their "stuff"
what is it's fuel burn rate at "cruise" which is 18-19 kts?

Betcha Boat "B" (which is over 7 times heavier) is burning fuel at a
comparable rate to boat "A".

If so, which boat is more efficient?

Your assumption is that Boat B is fully loaded with people and stuff.
Not often, I'd bet.

Boat A is similar to my Parker. I don't run it at 32-35 knots. I run at
23-27 knots under the right conditions, and keep my fuel burn "around"
10 gph. That's with four adults aboard. The gauge I watch most closely
is the ol' GPH meter. :}

At 40 mph, Yo Ho burns about 20 gph. No thanks.
