Thanks Chris, you got me! In my mind I saw Rushton, but got Ruskin.

I meant to refer to the ACA lateen sail as used back to Rushton's day, and the striking differences between Zephyr and the sailing canoe (p14http://www.enter.net/~skimmer/cs31s.pdfetc). From my vanatge point here I had it also that the lateen rig on Z seemed an odd marketing choice for the 70's on, that it further intimated a pontona connection, and a design decision to be true to origins. However, Gary makes a good point about the North American familiarity with the Sunfish! Sunfish are ubiquitous there, yet unseen here.

Graeme

Visions of social economy contrary to PCB's cherished Smith: Ruskin (Unto This Last) - Gandhi, communes, and on; Ruskin/Morris - Edward Bellamy (Looking Backward), Lane, New Australia Paraguayan Commune, and on. Another watershed, but still not many canoes in sight!

I notice that you're interested in the aesthetics of Zephyr, and thus I
find your malapropsim understandable and amusing. I don't know what a
Ruskin canoe would be, but since Ruskin was a famous art critic, I'm
sure that it would be aesthetically beautiful.

Ruskin is famous, for among other things, describing a particular
Whistler painting as "throwing a pot of paint in the public's face."
(This particular painting is worth seeing, at:

I do not know what he said about the designs of the artist Caillebotte,
who designed more than 20 yachts, see:

I suspect you were referring to Rushton canoes, which are, indeed, quite
visually pleasing. See

Ruskin, Rushton, and Caillebotte were all contemporaneous.

Hi Gary,

pardon my excitement - the possibility of gaining just a glimmer of further insight into PCB's thinking, influences, design ethic, and design evolution does that to me. I may have it wrong here - though things do seem to me to fit fairly well...


Hey, Graeme:
I should have been clear in that earlier message, where I meant too high from a windage point of view, not rowing geometry. I always found the Zephyr physically comfortable to row, just not a great performer and a problem in a beam wind. Possibly my homemade oars played a part in that; I'd like to use the pair I have now, made from a discarded double paddle, for comparison . . .

You might be right about the source of the clip-on leeboard, Bolger was adaptive about things like that and a great many other details. I actually used upper and lower slotted guards, so the depth of the board could be adjusted to match the shallow waters I usually sail in. It would, thanks to the skids on the bottom, sail somewhat to windward with no board, although it made noticeable leeway. Still, came in handy now and then.

I do think the boat is much more attractive "in the flesh" than in drawings or pictures, but I'm a sucker for long, lean boats.

The design was probably aimed at as much functionality as possible, at least it seems to me. Straight cuts in the ply made for easily assemble sides. (The artistry is getting the stem and stern rake exactly right.) 3/8 inch ply because people might think 1/4 inch was flimsy on a boat of this length. The lateen sail (81 sq. ft.) both to give a little more sail area than the standard 59 sq. ft. instant boat rig and to keep the center of effort low (and compensate for the extra weight). It also allows for easy reefing. It may have also been a marketing ploy; a lot of people were familiar with lateens because of Sunfish and hence it wouldn't seem threatening.

I've always been amused because Bolger was adamant that dories did not make good sailboats and I think this was his more dorylike design. But the bottom is wider and the flare of the sides less than a true dory.

Gary

The sides were a little too high from the windage point of view; in a beam wind sometimes I had to row with one oar to go straight. I suspect this would be less of a problem on a shorter boat with the same hull height just because there would be less hull. At 20 feet, Zephyr is a pretty long boat. I think the height of the sides were established for the maximum use of 4 x 8 sheets of ply; that dictated the 16 inch height. I'd be worried about shipping water under sail if they were much lower.

Whew. You said a lot.
Actually, it wasn't that Zephyr's sides were too high for rowing geometry, I think the rowing position was a little too far forward for good control, but if you rowed with someone along, that's where the oars had to be. The sides were a little too high from the windage point of view; in a beam wind sometimes I had to row with one oar to go straight. I suspect this would be less of a problem on a shorter boat with the same hull height just because there would be less hull. At 20 feet, Zephyr is a pretty long boat. I think the height of the sides were established for the maximum use of 4 x 8 sheets of ply; that dictated the 16 inch height. I'd be worried about shipping water under sail if they were much lower.

I'm no expert but I think the indifferent rowing came from too much wetted surface, which includes a 1.5 x 1.5 inch "keel" down the middle and .75 x 1.5 inch strakes on either side for further stiffening of the bottom and abrasion resistance. The rocker of the bottom may have had something to do with it, but we're getting beyond my expertise (if that's the right word for it :-))

I think Bolger knew that Zephyr wouldn't be a sterling rower, but it was designed primarily as a sailboat, and at that she is superb. She gives good performance with a minimum investment of time and money, and can accommodate 4 adults without serious crowding.

FWIW, we actually discussed Zephyr during my visit last October. I was opining that Zephyr would be capable of an Everglades Challenge with some minor mods: making the leeboard pivoting, making the sealed end compartments accessible with deckplates for storage and floatation, and extending the deck back to the mast partners for cockpit storage that would be protected from spray.

PCB went to some trouble to get the functional and attractive sheer on Surf #287 (& others). Not on Zephyr. Harold "Dynamite" Payson kinda suggests she's a longer Surf, and easier to build with her side planking cut straight edged. Gary Blankenship, who built and used a Zephyr for years, said she's indifferent under oars. As I recollect Gary mentioned a few years ago that the rowing geometry was not quite right, that the gunnels were too high.

I've wondered about that - PCB rowed by choice - impossible he would not be aware of the situation, so why'd he not trim a little off the topsides to gain the better geometry? I thought it likely he had deliberately opted for the building ease over some cost to the rowing/looks. And there was Dynamite's commentary.

Still, it bothered me. PCB was a rower, and the design dated from a time before his transition to unashamedly accepting logical outcomes imposd by the medium as suggested by Le Corbusier's "machine for living" concept. At the time PCB drew and said things like: for Cold-Water Sailboard #301, "I usually do use some flare and rake for the same reason I gave this one some sheer: I couldn't stand the looks of the functionally correct sheer which would be dead straight and level", or concerning Triple-Keel Sloop #328, that he was permanently cognizant of Colin Mudie's remarks about proper sheer.

Well, I think it's down to a certain integrity in the complex practice of PCB's striving for simplification. I think Zephyr isn't a longer Surf. Surf, or as Payson calls her "Crab Skiff", is just that, a design drawn from the Nth American crab skiffs. I now strongly think Zephyr must be derived from the Catalan `pontona', a type PCB would have encountered during his Spanish period, perhaps even whilst out for a row on the Spur of the moment.

I think this short article by Ben at "The Invisible Workshop"

http://theinvisibleworkshop.blogspot.com/2009/01/boat-that-split-in-two_08.html

grants quite a degree of insight into the Zephyr design origin, the designer, integrity of purpose, and much else: like, oh, why did PCB specify 3/8" plywood when he's longer, bigger boats in 1/4"? And could it go longer for speed like the "muleta"? (you beauty!)

Of course PCB once or twice said that Zephyr is a cheap sort of Wisp #411. Other than being closely sized to sleep two head-to-toe I see nought of the Catalan workboat in Wisp, much more of the Nordic. What do you think?
