Cork Boat

This one isn't indigenous to anywhere except perhaps the Realm of Whimsy, but it sure is outside the western boatbuilding tradition.
Cork Boat: A True Story of the Unlikeliest Boat Ever Built, by John Pollack, is a fun little book about one man's "dream" to build a boat entirely out of wine corks. Pollack first had the idea at the age of five or so, after his first attempt at building a displacement boat failed. Figuring that a boat made out of corks couldn't sink, he began collecting them, aided by his family. As he reached adulthood, he was still collecting corks, but the dream had become quite remote -- just something to think about, and likely never really do.

Pollack worked as a speechwriter for David Bonior, the Democratic Whip in the U.S. House of Representatives. But disillusioned by the nastiness and futility of politics in general, he quit his job and began to focus on the cork boat as a kind of therapy. The notion of devoting himself to something whimsical appealed to him and enabled him to turn his mind away from the dispiriting nature of national politics. He spread a wide net, asking restaurants around D.C. to save corks for him. He joined up with an architect friend who helped him design the boat and agreed to crew with him, although no particular trip or voyage had been discussed. After months of collecting, they realized that they weren't even close to the hundreds of thousands of corks required. They sought, and most amazingly, found the perfect sponsor in a company called Cork Supply Group, which distributes corks to wine makers all over the world. CSG ultimately supplied hundreds of thousands of corks in exchange for sponsorship. They went further, providing generous financial backing that was probably all out of proportion to the promotional value of the arrangement (which was, however, substantial). Like Pollack, it seems that the folks at CSG just thought the idea of a cork boat was really cool, and they wanted to help out.

Pollack briefly came out of "retirement" when he had an opportunity to work in the Clinton White House but, even there, he continued collecting corks and building the boat in his spare time. After the Supreme Court's dubious resolution of the Bush/Gore presidential race, followed not long after by the 9/11 terrorist attacks, Pollack's disillusion with politics was complete, and he turned his sole attention back to his project, with renewed vigor.

Pollack's greatest skill was that of organizer, and he persuaded dozens of people -- friends, relatives, and strangers -- to help him with the phenomenally tedious process of assembling the boat. (See below for details.) When complete, it was shipped to Portugal (home to Cork Supply Group), then trucked up the Douro River to the Spanish border and launched. Over the course of about three weeks, Pollack, his architect friend, and a revolving crew of friends and family descended the Douro, mainly rowing and occasionally sailing down to Porto on the coast.

Building the boat takes up most of the book, and it's unfortunate for we boaties, but probably better for most readers, that Pollack doesn't give much detail on the boat's design, and provides little in the way of illustrations. (The image above is the only one of the boat itself, other than the photo on the book's jacket.)  It was, of course, a raft, not a true boat.  The basic unit of construction was a hexagonal "disk" formed by bundling 127 corks together with long rubber bands. Dozens of these hexagons were stacked and sewn together inside a tubular net to create "logs." Nine logs were lashed together, four above five, with the front ends curving sharply upward in what the author imagined to look like a Viking ship. (It actually looked much more like a reed boat, which it also more closely resembled in its hydrodynamic properties.) Decks were added, along with two sets of oarlocks, a centerboard, rudder, mast step, and mast hoisting a square sail.

It's a cute book about an "adventure" that's neither harrowing nor grand. The whole idea was to do something offbeat and personal, something based on a private inspiration of no real social significance. As it turned out, the boat and the adventure did generate a number of pleasant social encounters for the author, and he took heart in the power of a silly but pleasant idea to bring out the best in people. Occasionally, Pollack veers a bit close to oversentimentality, but he seems like a sincere and likable fellow, and he's easily excused.

Not So Conservative

We've all heard it said – said so often that it's a truism – that boatbuilders and sailors are conservative. When I came across such statements in two of my most recent reads, however, I gave it some thought, as all truisms deserve. And while it may be true in a limited sense, I now say that, by and large, it's nonsense, and it's time we stopped perpetuating the myth of maritime conservatism.


The first instances appeared in The boat beneath the pyramid: King Cheops' royal ship, by Nancy Jenkins. She writes, "Boatbuilders, we have already noted, are extraordinarily conservative by nature, and their basic principles have remained much the same throughout the millennia that men and women have been putting to sea."

Now, Jenkins seems to be a pretty fair journalist, but not a serious student of boat origins, so perhaps we can forgive her for merely parroting the truism of conservatism that she picked up somewhere – perhaps from a learned source, perhaps not. (By the way, I can't find the previous allusion to conservatism that she refers to, but that might be her editor's sin, and not hers. There are subsequent mentions of it, and perhaps her editor moved things around.) But her statement in its context just doesn't hold water. The "basic principles" of boatbuilding, whether viewed over the millennia or across the globe, are quite diverse. Even in the context of her own book, she notes that the earliest Egyptian boats were papyrus reed floats and that, by the time of King Cheops, wooden boats existed alongside them.

Right there, we see two entirely different concepts of boatbuilding, side by side in a historical venue. The reed-bundle vessel floats because it is composed entirely of buoyant materials. The planked boat floats according to a different principle, by displacing water. Some centuries, possibly millennia, before Cheops had his ship built around 2600 BC, some boatbuilder came by this innovation by an incredible leap of intellect. And many of his colleagues saw the advantages of his new technology and copied it – hardly a conservative response. This is more especially so when one considers that boatbuilding lumber was unavailable in Egypt and had to be imported at great cost from what is now Lebanon, requiring that new trade routes and relationships be established.

And as for the boatbuilders who persisted in making reed boats (or, properly, rafts)? Those boats remained practical: cheap and easily built of materials available locally (possibly free), requiring far less specialized skill and few if any specialized tools. For anyone below the level of a noble, and for any purpose other than war, ceremony, or international trade, the reed boat remained not only practical, but in all probability, the only type available. In a very limited sense of the word, this might be termed "conservative," in that it retained an old practice. But there is no reason to think that the builders and users of these reed boats did do so out of any predisposition toward old ways; they did it out of pragmatism. And conservatism is not pragmatic: it is predisposed to the past on emotional or ideological grounds. When circumstances change, the conservative resists changing his methods.

Let's get back to Jenkins' assertion about the basic principles of boatbuilding remaining nearly unchanged. In addition to the reed raft and the plank-built hull constructed in the ancient Egyptian manner, pre-industrial boatbuilding methods included:

• skin boats

• log rafts

• rafts supported by inflated skins or by pottery vessels

• bark canoes

• dugouts and their variants

• numerous other plank-building methods



The list is not exhaustive, but it should suffice to disprove the notion that boatbuilding methods are, or were in antiquity, limited or static.

Paul Johnstone, in The Sea-Craft of Prehistory, also addresses the development of the papyriform wooden boat in Egypt. He notes how the long bow overhang, which is a natural feature of a reed boat, was also a practical feature on the Nile, where the boat could be run up on the shore for ease of loading and unloading dry-shod. He continues:

"Perhaps, however, it was found in time that while the overhang forward was convenient, it was safer if the after extremity was curved up to give some protection when running before the wind. Since reed structures are not self-supporting like wooden ones, the simplest way to achieve rigidity was to bend the aftermost reed bundle as far forward as it would go and then lash it to the hull. Such is the conservatism of sailors and ship-builders (a factor that runs constantly through this book), that this stern bent over toward the bow survived in the Mediterranean right through Greek and Roman times and even in recent Venetian small craft." [The parenthetical phrase is Johnstone's.]


It is hard to see the conservatism that Johnstone asserts. If the raised stern provided protection to Egyptian helmsmen even on the calm and protected Nile, surely it provided the same advantages to Greek and Roman helmsmen on the open Mediterranean – in addition, possibly, to protecting them from the arrows of pirates or other enemies.

Mounting the tall, raised stem- and sternposts on papyriform wooden ships involved some special engineering, given the boats' long overhangs and the weight of those decorative appendages. Planks were added that extended several feet beyond the enclosed hull fore and aft, forming "wings" over which the stem and sternpost were socketed. While we have few artifacts to prove it, I think it certain that the first wooden boats devised by Egyptian boatwrights did not have the papyriform shape, the challenge of creating the first wooden displacement hull from first principles presenting more than enough difficulties for any one boat project. If we agree that the first Egyptian wooden boat must have been fairly simple in shape, then the papyriform hull, with its special features to support the soaring stem- and sternposts, must have been a later innovation. Far from being a holdover from earlier reed-building practice (and it could not have been that, the methods of construction being too entirely different between reed boats and timber hulls to allow any direct transfer of methods), the papyriform ends were a conscious replication or mimicry of the reed boat's shape for symbolic purposes. This was technical innovation in boatbuilding in the service of what may have been a conservative aesthetic or religious impulse.

Johnstone later describes the Portuguese beach boats known as saveiros or xavegas, and what he calls their "smaller southern brother, the meia lua." (We discussed the xavega in a previous post.) Noting the types' distinctive design and construction details (flat bottom, extreme sheer and extremely high ends, keelless construction over frames), he cites T.C. Lethbridge, who in 1952 suggested that the types were quite ancient, and possibly ancestors of the ancient planked vessels of Celtic influence found in England and northern Europe (such as the Blackfriars ship). Johnstone writes:

[Lethbridge] supported this thesis by pointing out the important difference between beach and estuary boats. Beach craft always face a specific situation – through the breakers from a flat shore. A suitable form for this, with a flat bottom and at least one high extremity to face the breaking waves, could have been evolved many centuries ago and survive in a remarkably unvaried shape, except occasionally for the stern, from Gibraltar to Cape Wrath. No such conservatism was forced on the estuary boatman. He had no surf to worry about and no limitation on launching weight or depth of keel. Moreover, he had sheltered water in which to try out new ideas and these again might be stimulated by seeing strangers and visiting craft who would seek shelter on occasion in an estuary or inlet, whereas they would never except in an emergency run ashore on an open beach. Saveiros are launched from beaches into the open Atlantic on wooden rollers by oxen pushing on a wooden fork against the stern post, and Lethbridge's theory of beach conservatism indicates that they may be an ancient design. Shortage of resources, isolation and the need to be absolutely certain of the performance of their craft in the open Atlantic would perpetuate this conservatism."


A saveiro. Just visible at the right is the business end of the forked pole against the sternpost. Oxen push against the other end of the pole to launch the boat. (Photo from Johnstone.)

The logic here is mostly backwards. No fisherman would have risked launching and landing through Atlantic breakers without some strong motivation – such as being excluded from the safer estuaries by competition. Boats for calm estuaries, therefore, preceded the saveiro, and these estuary boats quickly proved themselves unequal to the challenge – and hence they evolved out of necessity, gaining high ends and perhaps internal frames in the process. It is the saveiro, therefore, that demonstrates innovation. If the design be an ancient one, that is because it is also a good one. One cannot know how many attempted "improvements" on the saveiro proved to be less well-suited to conditions, but surely many such attempts were made before the boats' users decided to let well enough alone. Again, this is not conservatism, but pragmatism.

Read any history of Western boat- and shipbuilding, and one sees constant change, constant divergence into new types. Look at a survey of the vessels of any large region or country (some examples: Canoes of Oceania (Special Publications - Bernice P. Bishop Museum; 27-29), Haddon & Hornell; American Small Sailing Craft, Chapelle; Working Boats of Britain, McKee; The Junks and Sampans of the Yangtze, Worcester), and one finds an amazing number and variety of types, each one of which evolved for some particular purpose or in response to some unusual factor of sea conditions.

Finally, view boatbuilding against nearly any other complex endeavor that has persisted for millennia, and boatbuilding comes out looking positively dynamic. Did architecture, agriculture, or government change more dramatically than boatbuilding over the centuries? Did the wheeled vehicle, or infantry tactics, or road building evolve further and into a greater number of directions? Has religion been more adaptive to changing circumstances? (LOL) With the coming of the industrial revolution and, later, of modern science, was boatbuilding behindhand in adopting new forms of propulsion, new materials, the benefits of microprocessor technology?

On the contrary. Boatbuilding has always been notably innovative. It's time to put the old "boatbuilding is conservative" myth to rest. Next time you hear it, speak up.

Surf Boats in India and Portugal

Reader António Fangueiro was kind enough to send photos of open, oared fishing boats which are launched through surf in Kerala, India.






For comparison, António also sent photos of a Portuguese type known as the arte xavega, also launched through surf:



Visible similarities include great amounts of sheer and rocker, substantial overhangs, high ends, and general suitability for the dangers of launching and landing through surf, although the xavega appears to have finer lines and to be more extreme in general. The final photo of the Portuguese boats seems to show a sailing rig being loaded aboard, while oddly-shaped oars appear to be the only form of propulsion for the Indian vessel. Of course, one would not expect to see Indian craft being launched by cattle as they are in Portugal. India's substantial manpower resources make up the difference. 

Thanks again to António for this interesting comparison.

Buggalow Comment

For reasons unknown, a reader's useful contribution isn't showing up in the comments section of a previous post about buggalows (a dhow-rigged vessel of the Indian Ocean), so I'll copy it here:

Hi Bob.
Wonderful blog you have here. I am portuguese and write also a blog on traditional boats, mainly of Portugal. I do investigation as a hobby on the roots of our boats, and keeping myself between Mediterranean and North Europe is already a huge circle. That´s why this blog of yours is very important, about the "not so glamorous" types of boats of the rest of the world. Many of your articles I could comment, and this one caught my special attention, because of the buggalow good construction and all on board different from the "crude" dhow, thar populated the Indian Ocean for centuries. Calicut, being in the Kerala region of India, has a past of european contacts, more strongly after Vasco da Gama. Looking at the buggalow I clearly see european característics, and although the Dutch and English had also presence in the region, I would say these european fine construction methods arrived and were kept in Kerala by the Portuguese positions there after 1498.


I have an article prepared to publish in the future which makes me believe even more strongly in this Portuguese influence in Kerala boats, this time in a Kerala fishing boat, lauched from the beach and with a half-moon shape. This boat is almost the same as the ones in central Portugal coast, the "barco-de-mar", considered very ancient in their roots, possibly of Greek, Phoenician times and their colonies in Iberian coast. Even the method of fishing used is the same as in Portugal, pulling the nets from the beach.

I may send you some pictures about these two examples of boats in Portugal for your analysis.

Best Regards,

Antonio's blog is extensive and looks very interesting, and Google's automatic translation function makes it somewhat intelligible to non-Portuguese speakers.

Antonio -- Thanks for your comments. Although I can't promise a well-informed analysis, I (and, I think, my readers) would be very interested in seeing the photos. Feel free to send them here.
