I suggest if one moved up a notch,
ie, a 60' boat with
40' accomodations, it could be a good move.

Long, skinny
hulls offer less resistance, better
pitching and rolling characteristics,
better speed for
given power with easier acceleration; an overall
increase in
performance and comfort compared to hulls,
let's say, closer to the length of
your accomodations.

Central location, fore and aft, of a sufficient
accomodation, say, the volume of a 40' cat, along with
that central location
of machinery and tankage,  atop
a pair of 60' hulls, keeps the accomodation in
the
most liveable portion motionwise of a bigger platform
enjoying greater
speed, performance and seaworthiness.


This platform doesn't need to be an
all-out wave
piercer like the camera boat or some of Gold Coast's
boats which
can present accessability and other
restrictions.  With a large volume but
short in length
cabin structure placed atop long narrow hulls,
asthetics can
be maintained along with a healthy
underwing clearance and other features
necessary  for
cruising like sidedecks, foredecks and stern/boarding
accessibility.

Length in a long and narrow hull translates to speed
and
comfort almost every time.  Placing smaller
accomodations on longer hulls can
have significant
advantage for long range cruising.

Best,
Bill
