Re: [bolger] Re: AUCKLAND CATAMARAN (BWOM)

Along similar lines for construction ease Bill Kristoffersons designs,
the 24 ft cat and tri are both very appealing to me.

Hi John,

Sorry to have given then impression I was any kind of expert. I'm
just someone with too much spare time and a certain amount of
knowledge in this area, mostly acquired directly from Lock Crowther,
a master of multihull design until his untimely death a decade or so
ago. The only plans for AC I've seen are the drawings in BWAOM. The
only multihull I've built was a 20' daysailer trimaran, over 40 years
ago.

I was trying to say that AC's design is 50 years behind modern
multihull thinking. Others have tried balanced jibs, planing hulls
and centreboards not mounted under hulls and found they didn't work
well enough to persist with. I don't know any other examples of a
rudder like this one, for good reason, as I'm fairly sure it won't
work just when it's needed, as the windward hull starts to lift.
Modern racing cats are proportionately wider than this and the
crossbeams are farther from the water and properly faired.

I assume this is the Seawind catamaran:
http://www.cancuncatamaran1.netfirms.com/aboutme.htmI don't think AC
would stand a chance against it. Your best bet would be to try and
find a used one -- possibly cheaper than building an AC. To gain an
advantage you could try something like a flat single-luff spinnaker
for light-air downwind sailing, when apparent wind will turn a broad
reach into a close reach.

By the way, Crowther tried angled daggerboards like Seawind's in
about 1961 and found they didn't provide as much vertical lift as
he'd hoped.

Hi Don -

You've made me a wonderful offer --If it's not an expensive call I
would appreciate it if you can give Howard a call and see wether or not he
actually built the Auckland Cat or still has the plans and just email me
the results as I don't see him on the Bolger groups membership list.

Hi Don -
Thanks for all your replies re. my request for info on P.B.'s Auckland
Cat. Sorry, about my oversight of not distinguishing that I'm NOT looking
for an all out racing cat, she would never keep up with the new ultralight
racing machines out there now . But, could she keep up with boats like the
Australian built "Sea Wind Cat" or the "Main Cat" that are so popular (and
costly) here in the local Florida coastal races ?

Hi Howard --

Thanks for your replies to my query re. P.B.'s Auckland Cat. I'd be
interested in building one to take part in Florida races like the Ft
Lauderdale and Miami race to Key West and the Columbus Day Regatta.
Scaling off the diagrams in BWOM it looks like the hulls are about 3' wide
and high, I can live with this by puting a Wharram (I've built 4 of these)
type cabin over the large hatch shown on the plans in order to meet race
requirements of berth, head and cooker inside.

What I'd like to hear from someone is - - - can this cat keep up with
the "Sea Wind" cats (30-33') that are so prevalent here ? These are
cruising class not all out races like the Roberts designs.

Ooo, Cartaphylla? I've had my eye on her for a while as a possibility
for my next project after the I60 is in the water. If she's really
being completed and built, that's good news.

Yes, I felt that if he was looking at the AC, he wouldn't be
considering cruisers.
A friend showed me a newspaper advert for a Bolger Centennial2 last
weekend. Without the high house. For the equivalent of us$3300.
Sadly the quality of the newspaper photo was so bad...not worth
scanning. A pity because the original would be a nice sailing
picture.

True enough, Don. John's first post was comparing (contrasting) AC
with "$200,000 plastic cats" without saying whether he meant racing
or cruising boats. The dialogue went on from there.

Not much headroom inside the AC, but plenty if you're sitting on the
deck, as long as you watch the boom.

Jeff's big complaint about Wharram is that his smaller (<30ft) boats
don't have even proper sitting headroom.

I admit a grudging admiration of his designs. They shouldn't work,
but they seem to meet the purpose for which they were designed. As
far as I know, considering all the rank amateurs who have built and
sailed them across oceans, they have a good safety record.

Howard

They range from 14 feet to 55 feet in length, and just about all of them have been built in large numbers.

Having corresponded with Jeff at some length, I'll toss in some info.

I don't know if he has any catamarans in the water. I tend to think
not. I appreciate the desire to stay away from an untested design,
and for many it makes a lot of sense. The question is whether there
is a design you like.

The Gumboots is in mid-development. He has changed the hull from the
last distributed drawing in order to get the boat into a shipping
container (dismounted, of course). I suspect that it will likely sail
well in a straight line. Whether the speed will be competitive with a
boat from a more experienced designer, only time can tell. Jeff has a
commitment to strong construction, but anything can happen in a one-
off.

There are two other Gilbert catamaran designs in the works. Hot Chili
is about 15 feet. One was built to approximately completed hull
stage, but the builder decided to go J-24 racing instead of finishing
the boat. AlleyCat is about 20 feet. The first boat is in build,
probably slowly. AlleyCat is not envisioned to be a fast boat, and,
IMHO, is marginal from a safety point of view since it relies on the
sailor not to press too hard.

He was just finishing the drawings of a 25 foot cruising schooner
last I corresponded with him.

Jeff is somewhat now and then with regards to communications. On his
Yahoo group, there was a comment that he has had computer trouble
lately.http://groups.yahoo.com/group/jgbuilders/messages

Does Jeff Gilbert have a track record of successful multihull
designs? I wouldn't invest my time and money in an untested catamaran
design.

They are much harder to design than it looks because of the stresses
generated by their stability and speed and the need to keep weight to
a minimum due to the limited underwater volume of the hulls that must
be slim to be fast. When sailing fast practically all the weight must
be borne on only one hull. If you are going to build it heavy to make
it strong, you might as well have a monohull -- only one hull to
build instead or two.

As one who learnt about the design of multihulls directly from Lock
Crowther, I'm confident in saying that AC would be (relatively) cheap
and easy to build but wouldn't compete with a modern racing catamaran
of a similar size. It would beat some of the cruising cats whose
design was not optimized for speed.

The design is even less sophisticated than Charles Cunningham's 1950s
designs, such as the Yvonne and Quickcat. Go to

http://www.geocities.com/Colosseum/Arena/9449/

... for information on the Yvonne, whose plans were available in 1954
and most likely still are. The class still holds championships.

AC's biggest deficiency is the centreboard arrangement. I can't quite
work out the fairing, if any, on the crossbeams, but they look too
close to the water anyway.

A non-Bolger alternative of similar size, cost, and ease of
construction would be Jeff Gilbert's "Gumboots", which also has
ocean-crossinga ccommodations on board where the Auckland cat is
strictly a daysailer.

Hi All -

Does anyone know if (Boating With An Open Mind - chapter 33) Colin Frankham of New Zealand ever built the Auckland Catamaran that Phill Bolger designed for him.? I'd really like to hear something about her performance. Seems to me that if one had access to the rig and sail that here would be a relatively inexpensive sailor that could really give those hi-class guys at the yacht club with their $200,000.00 plastic cats a real scare.
