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.

It's easy enough to balpark the numbers.

I happen to own a Boat "A", SeaRay 270 Sundeck, actually 26.5 ft, 5800
lbs dry, 320 hp I/O gas. It cruises 25 to 30 kts and burns 12 to 15
gph, averaging a little better than 2 nautical miles per gallon.

Boat "B" will typically burn 25 to 30 gph averaging about .7 nautical
miles per gallon.

So in theory Boat "A" is about 3 times as efficient ignoring weight.

Boat "B" however is 6 or 7 times heavier so on a per pound basis is
about twice as efficient as Boat "A".

It all depends what your boating objectives are.

My experience with larger boats indicates that fuel costs are a
significantly smaller percentage of annual operating costs. As an
example, on our GB49, fuel costs are less than 30% of annual, even in
a year where we burn 5,000 gallons. The big numbers other than fuel
are maintenance, depreciation/amortization, and insurance. If I had
to pay for marina storage that would reduce fuel percentage even more.

On the 26 ft I/O however, fuel costs are over 50 to 70% of annual
doing ball park calculations.

Based on all that, I'd conclude that higher fuel prices impact small
to mid size boats more than larger ones.

I should have qualified the efficiency question in a better way. I was
looking at it from the weight point of view and in terms of how much fuel
was being used to move it.

Agreed with the objectives issue. My point was that bigger boats aren't
necessarily "less green" than smaller ones, depending on how both types are
used. I'll bet I use less fuel on a leisurely cruise over to Martha's
Vineyard on the Navigator than I would spending an afternoon pulling kids on
a tube or waterskiing on a boat like the Scout I recently sold.

Now, the GB is a different story altogether. I couldn't burn a quarter of a
tank in a day if I tried.

I could. The 49 with twin DDs is quite a different animal that a 36
with a smallish single.
