posting of pictures of pitchpoling boats on Sailing Anarchy. It
seems to be a Sydney 18 or similar, and the rig looked like the AC
rig. I thought it might make an interesting amplification of PCB's
comment in the BWAOM writeup that the skiffs were 'carnivorus'.

No problem.
I forgot to add that Colin was highly dubious about the rudder set-
up on the Auckland Cat, and he has had a lot of multi experience.
I will be contacting him again soon, and will find out his wife's
email address.....you could do worse than have an exchange with him
if you are keeping on with it,

It would take you about ten minutes to get a fairly accurate number
for sail area.
Area of triangular portion is length of foot of sail x perpendicular
distance from foot to head x 1/2.
Measure the distance between the top of sail to its clew. Area of
roach is the length of this line x perpendicular maximum width of
roach x 2/3.
Add the two areas together. You will have to scale the linear
dimensions first. There are 2' station marks on the sailplan, and you
know how long the boat is.
Finding CLA of sail is not much harder.
In my perhaps-not-humble-enough opinion, the AC would be an expensive
experiment whose result you might not like. People tried some of its
design features and gave up on them over 40 years ago.
If you are going to change the rudder arrangement, think about
replacing the c/b with a daggerboard in each hull too. Why not ask a
few members of the SFMA what they think of the design? Ask them
whether there is enough clearance under the bridgedeck.

interesting.
Changing to two rudders precipiates a lot of other changes. The
kickup action of the central beam is meant to protect the rudder in
a high speed grounding, so is no longer appropriate. (Doubts have
been raised about whether this would work because of the long swing
radius: the "up" vector in the collision force would be small).
The GBE (Great Barrier Express) is one of the most popular 30' cats
ever. Jeff Gilbert is working on a cat about the same size with
similar accomodation and performance but simplified construction. At
least that's the idea.
Bolger had experience of the flat-bottomed trimaran Tarantula. It
would be interesting to know if he has repented of crude multi's. He
drew a cleaner entry for the Double Eagle.

Hi Don -
I can't thank you enough for your help in my search for information re:
the Auckland Cat and contacting Colin ( hope it wasn't an expensive call)
If I can get hold of a proper rig I would be very tempted to go forward
with the project. I'm a member of the South Florida Multihull Association
and someone might just have something usable. Bolgers write-up in BWOM
doesn't give any measurements or the square footage, unfortunately. I've
already figured that I would have to put a rudder on each hull which
shouldn't be too hard and perhaps some glassed - in foam at the bows to
give a finer entry.
Thanks again - Aloha - Jack - Ft Lauderdale, Florida

I phoned Colin Frankham about the Bolger Auckland Cat, and we had a
great chat about the glory days of NZ yachting, and his Bolger
experiences. Colin has been a Bolgerphile and has interacted with
the master for more than 20 years, and has built several of his
rowboats, sharpies, Black Skimmer and the bow steering cat. He
commissioned the Auckland Cat because he had a good rig and needed
something to put it on. Sadly Colin developed a back problem and in
the end did not build the design. Here are some snippets-
The bow steering cat was a total disaster as outlined in one of
Bolger's books...he couldn't do anything with it.
Colin waxed lyrical over his Black Skimmer. This was the one with a
centreboard, and which was for sale about a year ago here. He said
it was the best, so fast......he was drummed out of the mixed class
he was racing in after 'beating them to pulp'. Two fingers and he
was gone!
He has built several sharpies, and found that when they are wider
they are hopeless, but has found that Bolgers theories are usually
correct.
He also laughed heartily when relating that he has added foam bows
to a couple of lean fast rowing sharpies, which have transformed
them from slammers to well behaved faster boats. (dare I say like an
Oink bow?)
As to the Auckland cat, Colin had doubts about the rudder setup. He
also has doubts regarding the flat bottom hulls, having recently
owned a trimaran about that size with flattish bottoms to the
floats, which slammed like hell on the wavetops. He has owned a GBE,
which is the local 30ft equivalent of the Seawind, which others have
mentioned here, and way back a scaled down Haiwaian cat of the Rudy
Choy days.
Perhaps I should not mention this, but he said that while Phil is
brilliant, you have to be a little bit circumspect about some of his
advanced ideas....well, I guess we all know that!....caveat emptor.
Colin did not know of this Group, but his wife is on the net. I hope
he joins.
