Hōkūleʻa in Bar Harbor, Maine

Hōkūleʻa is a Hawaiian voyaging canoe in the midst of a multi-year voyage around the world. (We wrote about her previously here.) Launched in 1975, the double-hulled vessel is 62 feet LOA, with a beam of 20 feet and draft of 3 feet. Her hulls are cold molded, but she is considered to be a "performance-accurate" reproduction of the canoes that are thought to have been used by Polynesians to settle much of the Pacific, including Hawaii. Built originally to test theories about Polynesian seafaring techniques and technology, she has since become an ambassador of Polynesian culture and a campaigner for environmental awareness. There's plenty about the vessel, her mission, and her circumnavigation on the website of her owner, the Polynesian Voyaging Society.

We visited Hokule'a this weekend when she stopped in Bar Harbor, Maine. Because she was tied up to a pier with her rig stowed, we couldn't get a good view of what she really looks like, but we did go on board and took photos of some design and construction details. We also talked with Kaleo Wong, navigator on the most recent leg of the boat's voyage, about the mechanics of sailing a double crab-claw rig. (This is literally the first video we have ever done, so please be kind.)

Hawaiian voyaging canoe Hokule'a: lashing detail
Lashings between one of the main cross-beams and one of the hulls. The boat is entirely lashed together. There are no mechanical fasteners.
Hawaiian voyaging canoe Hokule'a: female idol
Hokule'a carries two idols on the vertical projections at the stern. On the port side (the female side of the boat) is a female figure. 
Hawaiian voyaging canoe Hokule'a: male idol
On the starboard or male side of the boat is a male figure. Where the female figure has prominent eyes and can see, the male is blind. But he holds a disc that represents the wisdom of the ancestors. Between the two of them, they have the perception and knowledge to guide Hokule'a safely.

There are five or six berths on top of each hull, all in a line, under a narrow sloped tarpaulin "roof," with tarpaulin covers over the entry side as well. Kaleo's feet rest on the starboard steering sweep, which is not steerable: it can only be lowered or raised to change the boat's center of resistance.

Hawaiian voyaging canoe Hokule'a: port berths
Two berths on the port side. There's just room to lie down, or sit up and place your feet over the edge. Accommodations do not look comfortable, and they're probably wet in bad weather. (This side was orderly. The starboard berths were a shambles of unstowed gear. Just sayin'.)

NOTE: We're obliged to Sym (5) and Ars Sonor for free use of the nice ambient music we used for the intro and outro of the video.

Bark Canoes in Arnhem Land, Australia

This short video clip, filmed in 1948 in Arnhem Land, Northern Territory, Australia, shows a few of the steps of building a bark canoe and a bit of paddling what appears to be a different canoe at the conclusion of a successful sea turtle hunt.

Source: (Australia) National Film and Sound Archive

What we observe of the canoe under construction:

  • The bark was stripped in a rectangular section, not the ovoid or lozenge-shaped sections as were used for the canoes of the Murray Valley and as seen in the image at the bottom of this post.
  • The bark appears to be charred on the inside of the hull. This might have been done to make it more flexible, to harden it, or to drive out insects and/or moisture and prevent rot.
  • The bark is folded roughly in half and held upright by stakes driven into the ground, which define the width of the hull.
  • The ends are stitched closed with what we presume is vegetable fiber. The stitching is on an angle for a bit of bow or stern overhang. The bark is cut back to a line several inches outboard of the stitches after they are in place.
  • A "thwart" is tapped into place to open the bark envelope to the desired width and keep it from closing up.
  • There are gunwale timbers of round poles (seen briefly at 0:24) that stiffen the sides but do not extend to the ends of the boat. We assume they are stitched/tied to the top edges of the bark, but can't make out that detail.
  • Abaft the thwart (assuming that we're looking toward the bow), a withy is tied between the opposite gunwales, apparently to keep the bark from opening too wide (which we assume could occur as it softens when wet).
  • The ends are caulked with a liberal application of tree sap, probably mixed with some hardening agent like ash or charcoal.
The canoe shown in use appears to have a different bow shape than one under construction. The stem is vertical; there are no gunwale timbers; and the visible thwart is shaped flat, not like the unshaped round stick as appears in the construction segment. In spite of the lack of gunwale timbers, the boat is well-shaped and apparently stiff, handily carrying its crew of four. Paddlers #1 and #4 have full-length paddles; crewman #2 paddles mainly with his hands but briefly uses a very short paddle or perhaps some other available implement; crewman #3 paddles with both hands only.

We've written previously about canoes in Arnhem Land as they appear in the movie Ten Canoes. The construction method shown there appears to be the same, but the bow shape is different. In Ten Canoes, the craft have a ram bow or reverse overhang that may have been useful in parting the tall grass in the swamps where they were used. In contrast, the canoes in the present video were used at sea, where an overhanging bow would serve to ride up on waves and keep the interior dry, and a straight stem would at least not tend to shovel water into the boat.


Gunwale timbers similar to those shown in this video appear in other Australian bark canoes, like the one shown at the bottom of the image below. The shape of the bow in this example, however, is quite different from either of the boats shown in the present video.
Australian bark canoe types
Three types of Australian bark canoes. The one at top is the Murray Valley style, with the ends plugged with mud or clay. The ends of the canoe in the middle are bunched and tied. The canoe at the bottom has timber gunwales and a stitched end of complex shape. (Source: Edwin Doran, Jr., Wangka: Austronesian Canoe Origins)

Canoe Paddle from Rio Beni

Canoe paddle from Beni River, Bolivia
Paddle from Beni River, obverse
This wonderful paddle, in the collections of the American Museum of Natural History, is from the Beni River, a tributary of the Amazon. It was collected prior to 1909 by a surveyor for a South American railroad.

The museum's description of the object is sparse, and even the exact location of its origin is ambiguous. The image listing says "Bolivia?," but old collection notes (see pages 311-312) say that it came from "the Beni." Rio Beni is entirely within Bolivia, although it flows into Brazil after joining other major rivers and changing names. The reason for the question mark, therefore, is unclear.

Although the museum's documentation does not say, one assumes the paddle was used with a dugout canoe. It was collected "by native boatmen," whom the surveyor evidently employed in his work. 

The paddle's appeal lies in its geometric purity. The blade is very nearly round, which is strongly emphasized by the painted designs on both sides. The shaft is untapered -- a perfect cylinder. And the grip is a simple triangle (apparently with a rolled top).

The design on the obverse of the blade divides the area into three concentric circles, the outer two of which are divided into quadrants. The reverse is two concentric circles divided into six wedges. The same four colors are used on both sides. A bit of asymmetry in the arrangement of the colors on both sides breaks up what might otherwise be a  too-rigid geometry.
