The Hawaiian Double Canoe Hokule'a

Hokule'a is without a doubt the most famous Hawaiian double canoe in existence. After a rough start beset by political and personal conflicts that nearly wrecked the project, she has gone on to complete many impressive voyages, the last one in 2007. Owned by the Polynesian Voyaging Society (PVS), she serves as an icon of native Hawaiin culture and a training platform for teaching traditional navigation and seamanship.

Hokule'a had her start around 1973, when Ben R. Finney, an anthropologist with an interest in the settlement of the Pacific islands, decided to scale up from a smaller, self-funded double canoe on which he had begun his investigations of the type. As described in his book Hokule'a: The Way to Tahiti, his original motivation was primarily scientific: to test whether the double canoe type had sufficient windward sailing capability to have made feasible the intentional colonization of the Pacific from west to east. This was in contrast to countervailing views that the colonization was either unintentional -- a result of unplanned drift voyages by castaways -- or that it had occurred from east to west, starting from the South American continent. (This latter theory was promoted by Thor Heyerdahl.)
Finney and his early partners founded the Polynesian Voyaging Society to help organize and fund the project but, according to Finney, the organization and the project were hijacked by nativist Hawaiians who wanted to use the canoe to promote Hawaiian cultural identity. Finney felt that the two objectives were almost entirely incompatible, and his book concentrates mostly on the resulting conflicts. (He acknowledges, however, that his narrative is quite one-sided.) The book is a tale of a terribly-managed project that just barely managed to fulfill its original goals in the face of tremendous personnel problems. Along with insubordination, there were fistfights and threats of mutiny.

Somehow, the Polynesian Voyaging Society turned the situation around later, and Hokule'a has clocked more than 32,000 sea miles on a half a dozen voyages, visiting most areas of the Pacific, mostly on cultural missions. (A circumnavigation is apparently in the planning stages!) Finney's name is hard to find in any context on the PVS website: he doesn't appear to be currently associated with the PVS, and it wouldn't surprise me if he dropped out immediately following the first awful voyage and has been placed under a taboo by the organization. PVS seems to be almost exclusively concerned with using the boat as a way to champion cultural identify -- there is very little about serious science on their website.

(In addition to the PVS website, much information on Hokule'a may be found on Wikipedia, although the article appears to hew closely to the PVS orthodoxy and gives little credit to Finney.)

The boat itself is unusual and impressive. The PVS calls her a "performance-accurate" replica, meaning that she is believed to perform like the traditional boats she resembles. Construction-wise, however, she's quite different. The hulls are cold-molded, with several intermediate bulkheads, rather than carved from single huge trunks. (PVS has subsequently built another canoe, Hawai'iloa, from huge Alaskan cedars -- about as close to the original construction as is possible at this time, since Hawaiian koa logs of the necessary size are no longer obtainable.) Steering is done with steering oars, which do not pivot side to side; direction is controlled by simply lowering the oars into the water or raising them out of it. With an LOA of 62'4" and beam of 17'6", she is much narrower than a modern catamaran of the same length but in keeping with the traditional configuration, which was narrow "due primarily to the limited ability of the wooden cross-pieces and coconut fiber lashing to withstand the phenomenal stress the ocean imposes on a widetrack double-hull craft," according to Tommy Holmes in The Hawaiian Canoe.

Her original rig was a very modest 540 square feet of sail area on two crab-claw (spritsail) masts, which gives her performance on the order of 3 or 4 knots upwind, and 5 or 6 downwind . She is capable of tacking to within 70 or 75 degrees of the wind -- comparable to the pointing ability of square-rigged ships -- which, based on the results of the first voyage, from Hawaii to Tahiti, was sufficient to have allowed double canoes to have indeed colonized Polynesia in an intentional effort of exploration and settlement.

Two Really Old Canoeing Books

Caveat: I'm addressing these two old canoeing books in a single post not because they're thematically similar, but because they're both of a comparable age, and because both were loaned to me by the same individual and I want to return them together.



Woods and Lakes of Maine, by Lucius L. Hubbard (1884, James R. Osgood & Co., Boston), has the lengthy subtitle "A Trip from Moosehead Lake to New Brunswick in a Birch-Bark Canoe to which are added Some Indian Place-Names and their Meanings." Hubbard's trip, conducted in 1881, was for purely recreational purposes. It involved one friend, and two Indian guides, and two canoes: one bark, one cedar/canvas.
 
A Maine Guide of the present day, Mike Everett, has written a nice capsule review of Hubbard's book. After condemning most contemporary books of this type as being too bigoted and too much self-absorbed by the authors' interest in killing things, he writes about Hubbard, in contrast:
"Lucius Hubbard’s book stands loftily above other Maine examples of the backwoods travelogue. The observant Hubbard and his party carried from the Allagash Lakes to the Musquacook Lakes, then down the Musquacook Stream and back into the Allagash, an impressive trip. Even more than Thoreau, Hubbard is an engaged participant in his story. He paddles. He works up a sweat on the portages. A good read and highly recommended."
Although Hubbard likes his Indian guides and admires their backwoods skills, there's a certain condescension in his descriptions of their characters. That condescension, though, was probably far less toxic than the attitudes of many of his contemporaries. If we can avoid viewing our forebears with today's attitudes, I think we can accept Hubbard's attitude toward other races as being sincerely well-intentioned.

There are many good, detailed descriptions of the outdoors, woodcraft, and paddling throughout the book, especially a fine description of how to make up a portage pack out of a canvas tent. Other detailed explanations include how to portage a canoe; how to call a moose; and how to pole up rapids; and he devotes much space to a discussion of the beaver's domestic arrangements. His friend, "the Captain," provides comic relief in his frequent complaints about weather, mosquitos, and hard work in general. Hubbard should be read with a large-scale map in hand, for most place-names haven't changed much, and one can follow his party's every move from Moosehead Lake to the St. John River.



By Canoe and Dog Train Among the Cree and Salteaux Indians, by Rev. Egerton R. Young (1898, Charles H. Kelly, London), is more memoir than outdoor adventure. The good reverend devotes most of his attention to his decades-long missionary activities (1860s through 1880s) in areas south and west of Hudson Bay. And although he is insufferably pious, bigoted, and self-righteous, he was also one heck of a dedicated missionary with impressive physical toughness. In order to bring the Word to the Indians (whom he usually calls Pagans) across a territory roughly the size of England, he traveled thousands of miles annually, covering up to 60 miles per day by canoe, and sometimes 90 by dog train, the latter in temperatures to 50 below zero (Fahrenheit), and sleeping in the open. (The dog train differs in a couple ways from a dog sled. It's basically a toboggan, not a sled, and it's pulled by dogs in line ahead, not spread out Eskimo-sled-dog fashion.)

There's not much detailed desription of canoeing practices, but a couple of illustrations are worth reproducing. (Unfortunately, the illustrator is not credited in the book. Based on both style and accuracy of rendering, I suspect there were two illustrators.)

The first shows an accurately rendered Cree canoe, by an illustrator who clearly had good source material to work from.

The next one, unintentionally comical, is captioned "We have looked death in the face together many times," but the page referenced makes no mention of the bizarre scene depicted. I can't figure out if the canoe is miraculously ascending the waterfall, or if it's being unaccountably swept down it stern-first from the apparently calm lake above. Either way, this illustration betrays the illustrator's lack of understanding of his subject matter -- a marked contrast to the excellent rendering immediately above.

The Unusual Beothuk Canoe

The Beothuk Indians of Newfoundland were completely exterminated by the early 19th century by a combination of direct, conscious oppression by European settlers (and, to an extent, by Micmac people in Newfoundland) and by diseases unwittingly brought to them by Europeans. Because the Beothuk attempted, in the majority of cases, to avoid all contact, including trade, with Europeans, little is known of them. They did build quite distinctive birch bark canoes, of which certain details are known. Others, however, will probably remain forever mysteries.

Beothuk canoes were from 15' to 20' long, and almost a pure V-shape in cross-section throughout their entire length, with just a bit of rounding off of the apex. They had dramatic sheer both fore and aft, and amidships the gunwales rose in an even more dramatic hump, a feature that I'll discuss below. The boats were amazingly deep (for canoes) between the humped gunwales (or "wings"), which were held apart by a particularly long thwart.

With their V-bottom, the canoes would have been extraordinarily unstable were it not for another unique aspect of the Beothuk design: they relied on interior ballast, in the form of stones. These were covered by battens and moss, skins, or some other soft material for the comfort of the paddlers. With their stone ballast, they would have been quite stable in their intended use, which was coastal and even offshore waters. The Beothuk took their canoes as much as 40 miles offshore to collect birds and eggs from smaller islands -- further than any other bark canoes used by Native Americans. They were not used for inland waters.

It may be presumed that they were also used to hunt sea mammals, as the Micmac did in their "rough water" canoes, which also had a humped gunwale (although not nearly so dramatic). In both cases, the raised gunwale amidships would have helped keep out water in rough conditions, while the lower sheer fore and aft of amidships provided clearance for the crew to wield their paddles. The Beothuk's V-bottom and great flare would have given the boat tremendous secondary stability (much like a Banks dory), which would have come in handly when hoisting a captured seal or porpoise over the side.

Beothuk canoes were unique among North American bark canoes in having a backbone. Not a keel, but a keelson, laid inside the bark covering and below the ribs, provided longitudinal strength. Most other construction details followed standard American Indian practice, with the possible exception of the gunwales, more on which below. Like other bark canoes, they had sheathing against the inside of the bark, held in place by bent ribs, and were lashed together with split spruce roots. As cedar was unavailable in Newfoundland, spruce took its place for the sheathing and ribs.

There is some disagreement about whether the bottom was deeply rockered or straight. A sketch from 1768 (below) shows the rockered interpretation, and the artist described the boat as being like a "half moon" in profile, "nearly, if not exactly, the half of an ellipse."

Three grave models have been found, however, which show a straight bottom with a distinct break where the ends rise from it, and the last surviving Beothuk, a woman named Shanawdithit, made a model in 1826-27 (shown below) that also had these attributes. Although boat models made by indigenous people are often inaccurate, I'd say the straight bottom seems more likely.

Another design feature about which there is some disagreement is the shape of the gunwales. The grave models referred to above had the gunwales rising to a smooth curved hump amidships. Shanawdithit's model, in contrast, shows the gunwales rising to a point amidships, as does another model held by the Royal Scottish Museum which, according to Kenneth G. Roberts and Philip Shackleton in The Canoe, was also of Beothuk origin. This is further supported by the 1768 sketch above, and by the accompanying description that noted the sharp angle and stated that the gunwales were formed of two pieces joined in the middle. One more bit of support appears in a very bare description dating to 1612 that compared the Beothuk canoe to the wherries of the Thames River in England. Although this description doesn't refer specifically to the sheerline or the gunwales, the "broken" sheer of the Thames wherries is perhaps their most obvious visual characteristic.

Adney concluded that the humped version was the correct one (see image below), saying of the "broken" interpretation: "This hardly seems corrrect since such a connection would not produce the rigidity that such structural parts require, given the methods used by Indians to build bark canoes." He speculates that the 1768 observer saw a damaged canoe, in which the humped gunwales had been broken, creating the sharply pointed sheer.


Reconstruction of a 15' Beothuk canoe in The Bark Canoes and Skin Boats of North America, by Edwin Tappan Adney and Howard I. Chapelle, Smithsonian Institution Press, 1983. (Click for larger image.)

I cautiously disagree with Adney's conclusion. He seems to be ignoring the unique construction feature of the keelson which, I believe, would impart the necessary longitudinal rigidity to the structure, reducing or eliminating the stress on the gunwales which, in other bark canoes, provide the majority of longitudinal strength. The preponderance of evidence, I believe, points to the pointed gunwales.

One more interesting feature to note in Adney's reconstruction is the nearly vertical post extending above the stems at both ends. This was used, he says, to raise the ends when the boat was inverted on the ground for use as a shelter. Raising the ends would have been necessary, even with their extreme rise, because of the equally extreme rise of the sheer amidships.
