No Beam, No Do?

[TrentePieds]

There is nothing particularly new in this. The article states: "Die "Lux" ist wirklich ein besonderes Boot, gebaut, um ohne zu gleiten über die Rumpfgeschwindigkeit hinauszukommen, dabei fahrtentauglich und bewohnbar."

Which translates as: Lux is certainly a "special" boat, built to get around the limitation of "hull speed", while remaining easy to sail and habitable".

Well, yes. "Cut a heel and chop a toe" as Gebrüder Grimm put it in "Cinderella". The moral of that tale as you know, is that you may make the sacrifices yet wind up with nothing.

The article begins: “Ein Kieler Werkstoffkundler beließ es nicht bei Laborversuchen, sondern baute in mehrjähriger Tüftelei die beispiellose "Lux". Bordbesuch Wenn Jürgen Rudolf über sein Schiff führt, ist es ein bisschen wie mit dem Ei des Kolumbus. Fast alles hat er anders gemacht als üblich, fast immer sind es ganz logische Wege, die er gegangen ist. Und doch sind es fast immer solche, die andere vor ihm in der Konsequenz noch nicht beschritten haben.”



Which means: “A Materials Engineer from Kiel [translator's comment: Everybody is an “engineer” these days ;-)] didn't leave it to laboratory experiments, but built, over several years of "fiddling about", the unprecedented “Lux”. When Jurgen Rudolf shows his boat, it is rather like “Columbus' Egg”. Almost everything he has done, he has done in a manner different from the norm, yet always in a logical manner, and always along paths where no-one has walked before.”

That is clearly poppycock, codswallop and marketing fluff, for elsewhere the article refers to "Schärenkreuzer", the "skærgårdskrydser" that a hundred years ago was all the rage in Sweden as an evolution of the English "Plank-on-Edge" philosophy.

And fifty or more years ago Billy Garden had a 50-foot "commuter canoe" (Tlinglit?) that had a 3 foot beam and a three-horse one lung Easthope engyne. Or something like that. Here is an interesting thread about that "experiment" from a boat design site:
Missing Bill Garden designed launch - Anybody seen it? - Page 2 - Boat Design Forums



It would be nice if those who write for the “yachting press” had a better grip on yachting history. Prolly wouldn't wash with their readership though ;-0)!

Of all the 8 sailboats I have owned the Ultralight narrow beam and high sail area to the weight boat is still the very best sailing I have ever experienced in over 40 years of international racing and cruising.
The Fast 40 was also an American built ultralight sailboat. 8 foot beam.
Must say that the LUX 49 foot aforementioned that has 7 to 1 beam to length is indeed very narrow. That's why it sports 10 foot draft. More than enough sail area at about 600 sq feet for 6000 lbs.
I would love to fly in this one.

Looks as if built for speed not practicality as a cruising boat. To each his own.

Robert Perry, NA, designed the Far Harbour 39 as a "container yacht" meant to fit in a standard 40' shipping container.

Here is a link to that site. Unfortunately that site requires Flash, so I cannot view it on my iPad

The Swede 55 was one of my dream boats many years ago.
A long lean boat, less than 10 feet of beam.

In fact, I have some information and illustrations on the design in my notes, and will add a profile about the design it to the thread I started called "Outstanding Boats."
---------

Since the displacement of the boat that started this thread was mentioned, here are the specs for a Swede 55 for comparison:

LOA – 53 feet / 16.15M
LWL – 39 feet / 11.89M
BEAM – 9.58 feet / 2.92M
DRAFT – 6.42 feet / 1.96M
DISPLACEMENT 16,640 lbs
BALLAST – 9,036 pounds
SAIL AREA – 694 SQ.FT. / 64.47 SQ. METERS
Sail Area/Disp.1: 17.10

The Swede 55 has an offshore cruising interior with multiple berth, some nice Teak wood furniture, head, galley, etc. from the ones I have seen, I would not mind using it for cruising. Much nicer interior than some strict racing boats. Of course each boat may be outfitted differently.

Skinny boats have their virtues. Don't knock em till ya tried em! We have a long one down they way from me here, looks like 60-65' and fully equipped forgoing places far away. Bet it goes to weather! Bet it goes anywhere. I'll have to get a photo of it to post. Sure would like to know the make but never see the owner around.

And of course, Mr. Perry more recently designed the gorgeous one-off double-ender 'Sliver', 62 feet long and a bit under 10 foot beam.

No, FAST 40 is what I was thinking of.

The first version of the MACGREGOR 65 would be very similar, 12' beam with 65" LoA.

The later version of the MACGREGOR 65 PILOT HOUSE had the same dimensions but was a LOT heavier and more oriented to cruising.

Yes. Good to mention that. As I recall, it was a Carbon Fiber hull, and something new for Perry.

I forgot about it, as I was thinking of the Swede 55.

[Cadence]

Look at some of the Blue Nose type. Wine glass hull and not to beamy and loaded with ballast. I feel sure a non working boat could have much less beam.

[Steadman Uhlich]

I crewed on a Hobie 33, which I considered a long and narrow boat, especially because I was also crewing on a j-24 and J-29s at the time, which struck me as "beamy" in shape.

Obviously, both are shorter than the boat that started this thread.
I am posting this because I still think of the Hobie 33 as a narrow or skinny boat.

HOBIE 33

LOA: 33.00' / 10.06m
LWL: 30.50' / 9.30m
Beam: 8.00' / 2.44m
Listed SA: 428 ft2 / 39.76 m2
Draft (max.) 5.50' / 1.68m Draft (min.) 1.83' / 0.56m
Displacement: 4000 lbs./ 1814 kgs.
Ballast: 1900 lbs. / 862 kgs.
Sail Area/Disp.1: 27.25 Bal./Disp.: 47.52%

MacGregor 65

LOA 65.00' / 19.81m LWL: 63.00' / 19.20m
Beam: 11.67' / 3.56m Listed SA: 1676 ft2 / 155.7 m2
Draft (max.) 8.50' / 2.59m Draft (min.)
Displacement: 22000 lbs./ 9979 kgs. Ballast: 9000 lbs. / 4082 kgs.
Sail Area/Disp.1: 34.29 Bal./Disp.: 40.91%

I will agree with some features of long and narrow but not with all claims.

Imho the best ride off the wind is in extremely flat and beamy light boats.

Upwind yes I love long, light, narrow and ballasted up. Except ... 90% of our sailing here is ... downwind.

Upwind, this thing could be a tool of choice - as long as one can live in a 2,04 m interior.

So, a potentially great coastal skerry-country daysailer.

On the second thought, I have just measured our cabin and it is actually only 1,90 m.

On the second second thought - you may still remember this other boat.

I could not resist: that's her back in 2010:

Yep. Long, narrow, light and damn sexy.

I think LUX is a superb try. Maybe I will try building one in alloy.

Cheers,

No doubt about it! Campaigning a KingsCrusier29 - another compromise cruiser/racer - in the Straits of Georgia under PHRF rules we did just fine to weather and got wiped out, consistently, going downhill.

The KC29 just couldn't quite forget her "metre-boat" ancestry :-)

For the time being, I'm stuck ashore, so here is a perfect time to lay down some desiderata for a CRUISING boat "fit for her trade", i.e. for CRUISING in the Salish Sea. I feel a fit of "cod's head and mackerel's tail" coming on, and also a fling with diesel-electric propulsion. Not "pure" electric, not hybrid, but sensible replacement of the mechanical reduction gear with a generator/motor arrangement a la electric locomotive - and a la some large ships.

Maybe I'm just hallucinating because of the recent threads touching on electric propulsion and because of the recent query by the Lady form Brazil. I can think of lots of advantages for a cruising boat that takes advantage of the flexibility in terms of location of components afforded by diesel-electric drive, and of having, as a by-product, more whack of juice available for high consumption conveniences.
