Subject: [PCW] re camera boat

Mr. Harrott wrote,

"A fifty foot boat with
thirty foot accomodations is a
tough sell"

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

Dear Mark,

We have already designed the boat as described by Bill and construction is
well underway in Paraguay at www.dreamperformance.com  This is the Domino 20
design . The description of the Domino reads as if Bill had written it.  I
have raised the issue of anchoring, mooring etc with some of the extreme wave
piercer hulls, in several articles. I also pointed out that a lot of clients
consider the longer hulls, be they wave piercer or "normal', to be wasted
space.  Most clients want to fill up all the spaces. There was an old adage in
boat design which went:- "keep one third of the length for the boat". This
meant that if you made it longer and kept the ends empty then you would have a
much better boat. This is just as true today but commercial pressures of one
sort or another mean that this advice is seldom heeded.

Regards,
