Hi, Roger Hill here.
Although I sometimes enjoy reading the various topics that crop up
on this
forum I don't often contribute, so here goes!
It's great to see you contribute, Roger. We would all welcome hearing
from you more often as there are few people on the planet with the
expertise in power catamarans that you have.
Tell us, if you will, what powercat designs you are working on these
days?

Agree with Bob Austin - displacement has a dramatic affect on fuel
economy.
For example:
My 40' LOA Maxweld aluminum power cat has a planing hull. I was
disappointed by the planing speed fuel economy. One of the boats ahead
of
mine in the production line had the identical hull and power plant, and
the
builder and professional delivery crew reported outstanding numbers on
that
boat. My boat consumed 40% more fuel. I was convinced that there was a
problem with the boat, but the power plant checked out fine, and there
were
no obvious hull deficiencies other than it was slightly stern-heavy.
I finally tracked down the owner of the previous boat. He confirmed
that
the numbers reported to me were indeed accurate. But there were a few
differences between our boats. His was used as a day-boat by the
fishing
lodge he owned. Mine is a cruising/liveaboard/fishing boat. He had a
minimal cabin, small battery bank, small fuel tanks, smaller water tank,
no
galley, tiny head, no berths, etc. etc. It was the same hull and power,
but
that's where the similarities ended. My boat weighs almost double what
his
does.
So I don't feel quite so bad. Double the weight, and only 40% more fuel
usage. I shouldn't complain.
However, I've discovered an amazing thing. If I slow down to
displacement
speeds, my fuel economy is nearly 4X better. Who knew? I've
occasionally
run at slow speeds, but hand-steering is very tedious at that speed.
I'm
having an autopilot installed right now, and next spring I'll be doing
my
long runs, if I'm not in a hurry, at 8 kts, letting my 'third mate'
handle
the wheel. On the other hand, if I want to get somewhere in a hurry,
and my
wallet is feeling fat, I can always crank it up to 25 kts.
One of the primary advantages of cats, even the planing flavor, is their
ability to run very efficiently at displacement speeds, and yet run at
considerably higher speeds as well.

Remember that the cost of a hull is a fraction of the total cost of
building a
boat. You have to also figure in engines, all systems, upholstery,
finish of
the entire interior, paint, fairing, electronics etc.
Also a bare boat's speed (and 8800 lbs is light for a boat this size)
is
related to its weight. Once you put in 200 gallons of fuel (1400 lbs)
and 200
gallons of water (1600 lbs)--you have added another 3000 lbs, and will
find
that the efficiency will decrease.
Very difficult to compare the efficiency of a planning and a semi
displacement
hull, as well as a gasoline outboard to an inboard diesel. My bet is
on the
PDQ--and as Henry says a used PDQ will cost considerably less.

Great points Bob,
I do the same with Wild Wind IV. She is also very heavy with all the
things I
have put in her and should most likely take most of it back out. With
the 1800
gallons of fuel on board she sure is less spirited.
In addition to be able to go fast when one wants to, I find the ride
much
better at a faster speed particularly when the wind is on the beam as
was
expressed by the crew of Chrysalis. The ability to run for it is a
great
advantage as I have done in the open water like just before coming in to
Ketchikan AK from the south.
I can't imagine a cruising boat without an autopilot. Many times I will
steer
the boat with the autopilot even in rivers.

I believe "displaning" was coined by Pete Brady not Malcolm.

Hi, Roger Hill here.
Although I sometimes enjoy reading the various topics that crop up on
this
forum I don't often contribute, so here goes!
I have been away for a couple of weeks and only yesterday picked up on
some
dialogue going on about fuel efficiency and comparisons between the
Seles
and the Prowler VT950.
I designed the Seles cat so know a little about it and how it performs.
I don't actually know exactly what the fuel burn figures are for that
boat
and am not sure how accurate they are. The 0.88L/NM figure at 15 knots
is
presumably off their web site.
As a general rule I do not believe any statistics published about
designs if
they are done so by someone with a vested or commercial interest in that
boat and I do not publish performance and fuel consumption figures of my
own
designs unless they are the results from an independent test.
The Seles 10.2m and the Prowler 950 are of a similar size and
displacement
(10.2m X 4.5m Seles versus 9.5m X 5.5m Prowler) but they are completely
different hull forms. The Seles cat is a pure displacement hull and the
Prowler is a planing hull (all be it a rather radical shape for a
planing
hull) and by that fact alone it is extremely difficult to make direct
comparisons. The handling and sea keeping ability, stability, motion at
rest
and in a seaway, etc. would all be quite different.
The optimal engine size for the Seles design is in a range of 50 to 70
hp
per side with outboards and I think that the Prowler is more than double
that amount.
The fuel consumption figures that I do have for a sister ship of the
Seles
fitted with a pair of 60hp Yamaha 4 strokes, loaded displacement of
4,153kg
(Prowler has a published figure of 5,500kg loaded) range from 3700rpm,
12.75
knots, 1 L/NM both engines, 4300rpm, 15.6 knots, 1.28L, 5,500rpm, 21
knots,
1.8 L/NM.
For a reasonably well built (down to designed weight specified) planing
cat
of similar dimensions we would expect (figures for a 9.5m planing cat
fitted
with a pair of 200hp Evinrudes) at 4500rpm, 25 knots, 2.31 L/NM both
engines
and a top speed of 38.1 knots.
The Seles cat was a 'one off' built in Auckland New Zealand and is
currently
operating very successfully as a bare boat charter vessel in Queensland
Australia. There have been several of these 10m displacement hull cats
built
with various layout and deck styling changes and there is currently
underway
in Australia a new 10.65m production built version by Argus Boats.
The company that built the Seles cat has since been 'reformed' and is
now
South Pacific Boat Builders.
I have no information on what the PDQ 34 goes like so have not included
it
in this conversation.
To convert from metric to those old fashioned figures a US gallon is
3.785L,
a kilogram is 2.2046 lbs, and a metre is 3.281 feet.
Regards
Roger Hill

Hi Georgs,
Thank you for your nice comments although I am certain that there are quite
a few people who know a bit more about power cat design than I do!
In response to your question, we do seem to be quite busy at the moment
with
a variety of different and interesting projects.
Compared to this time last year when we had come off the back of a busy '08
year and came to a screeching halt for the beginning of '09.
Currently we have in progress a 21m semi commercial alloy planing power cat
for a retiring fisherman who will still do the occasional bit of work but
more likely use it as a private vessel or for charter work.
There is a new 14m composite planing power cat to start for a client who
intends to use it as a touch and go platform for his Robinson R44
helicopter!
We will also be starting this month on a 15.2m displacement hull power cat
to be built in Korea as a production moulded unit.
Also progressing through the design stage is a new 10.65m displacement
power
cat under way in Australia, this is also a production moulded boat.
A new 20m displacement hull cat is well advanced for a NZ client as a
private vessel that is being built to survey so that it might also do some
charter work.
There are a couple of new projects in alloy and composite underway in China
as well.
In the preliminary stages there are several other power cat and sailing cat
projects and the level of enquiry is very high, so for a small office (2
people) you could say that we have more than enough on at the moment.
Best regards
Roger Hill.
