Ataraxia
Speaking of Ataraxia, (see "Open Mind") has anybody run across this
boat recently, or have a report on how she's doing? Is she living up
to her "breakdown-proofing?"

Does anyone have any pictures of Ataraxia, the dipping lug motorsailer
shown in BWAOM?

in Corsica for an experimental oyster rearing project. We ran the beast at
near full-load, 24 hrs. a day, 7 days a week, for nearly a year, shutting
down only to check the oil, re-fuel, oil-and-filter changes and some other
small routine stuff that I've forgotten. It never gave a minute's worth of
trouble in that time. (The project collapsed before the engine gave out.)
However:
1) Was it ever NOISY!!! I think the cooling fins may have amplified the
normal diesel racket. The cooling fan might have contributed its part. In
any case, the beast was LOUD!!! About the only ambient sound I could hear
within 50'-100' of the beast were the occassional Mirages making high-speed
low-level training flights over the lagoon. If I was in the vicinity and
someone wanted to get my attention I either had to notice visual signalling
or the unfortunate had to enter the ZONE OF NOISE and tap me on the shoulder.
I can't recall if it was a Deutz, or something else, but I would guess the
noise situation is pretty much inherent in the type;
2) It processed a lot of AIR! I have no idea what cfm the fan was blowing at
full chat, but, if memory serves, the blower intake was approx. 12" in
diameter and it certainly pulled a significant draft. This would pose some
problems in the confines of a small boat:
a) It would have required intake and outlet ducting something in
excess of 115 sq. in. cross-section - providing two great channels for
ducting noise where it wouldn't be welcome, and
b) providing two big holes to let water into where one would least
want it to go.
3) The beast got pretty darn HOT! This is a pretty subjective observation, as
water-cooled blocks also get too hot to touch, but the cooling fins seemed to
be hotter than anything my "dermal thermometer" had encountered, short of the
exhaust pipe on a motorcycle. (PSSSTT!!! :-(o)
Ataraxia's design addresses these issues - but it is a pretty big boat. I
think the smaller the boat, the greater the difficulty of making an
air-cooled diesel an unobjectionable companion.

One of PCB's designs in MAIB in the recent 2-4 years was for a long range power cruiser with a Deutz
oil cooled diesel. This is essentially an aircooled diesel, because a radiator is used to cool the
oil. Deutz also has pure aircooled diesels. It makes for simpler systems, because you don't need
water pumps and through hulls. The hot air by product might be a pain to get rid of in the tropics,
but in my part of the world it would be welcome.
I have given a lot off thought to a Wyoming with a pair of 50 hp Deutz diesels coupled to DBD drives

Light weight, shallow draft and fast, get way up the rivers and shallow bays.

This is an interesting concept.

Gary, I've looked at the picts in the wing keel file, how about putting up

Resolution might be a heck of a deal if she's what you want and you live
near Gloucester or if you'd like to cruise home from Gloucester.

"Resolution" real soon now as a motor boat. Susanne has some changes she

particular definition of low tech and high reliability.
PCB showed plans in MAIB for a long distance power cruiser (named
Tahiti, as I recall) of about 35'. In the issue that I received
yesterday, he showed the tender designed for it, and said the
building of the prototype was proceeding.
It seems to me that he showed another ocean-crossing power cruiser
about the same time, but I don't remember the details. He has
designed a number of power boats with ocean crossing potential. I
would work out your performance/cost profile and ask him directly.
On the motorsailer front, the first things to come to mind are the
Solution 48 (imagine a very big, steel Teal), the Loose Moose (aka
Advanced Sharpie 39) which was designed for power in canals and sail
on the high seas, the Double Eagle catamaran (and variants). And of
course, his own Resolution.

Looking through Boats With An Open Mind I find myself returning to
the Ataraxia design. As I recall, Bolger said the article was for an
upcoming publication on reliability. If I remember right, the boat
was built by Story (sp?) boatbuilding somewhere in MA.
Has anyone ever seen the boat or heard how the design worked?
Are there any other Bolger designs that were of the low tech, high
reliability, seaworthy long distance power or motor sailer(or?)
cruising type? (I'll take a breath after reading the last out
loud.)
Thanks to all for the posts -- it is always a treat to read this
