[PCW] Fuel economy, Chrysalis across the Atlantic

[kevinr]

I don't believe either length or displacement is a fair comparison,
especially when comparing a heavily built displacement vessel like Nordhavn
to a power cat that is capable of achieving twice the speed (thus has to be
more weight sensitive). I think the industry (manufacturers) should start to
publish either square footage or even volumetric measurements (gross
tonnage?) so that the buying public can easily compare different models.
This after all is how the building trade has been doing it for years, it's
not enough to say it's a "4 bedroom, 3 bath house", but also sq. ft. "under
air" and total sq. footage.

This is especially true when trying to compare power cats with monohulls.

I'm only looking at
 plans here and would be interested to here from
people who have been
 aboard both. "

I ask, what is a valid basis for comparison of multi's
vs mono's?

WWIV is listed on Malcolm's website as displacing
#73,819.

This falls between the Nordhavn 46 #60,000, and the
Norhavn 47 #85,000.  WWIV certainly has more
accomodation than either of these.

My current project, a #56,000 powercat, 62', comes in
between the Nordhavn 43 and 46, weightwise.

The Nordhavn 55 weighs in at a whopping 56.6T, twice
my displacement!

Is length comparison apples to apples?


regards,
Bill
