The Vattai of Tamil Nadu

Examples of traditional frame-first boat construction in Asian cultures are rare. Throughout the Far East, Middle East and east Africa, shell-first construction of planked boats is the norm, where it is used for everything from sampans and junks to dhows. One of the few exceptions is the vattai, an open, sail-powered, flush-planked (carvel) fishing boat common in the state of Tamil Nadu, in India’s southeast.

The vattai is described by Lucy Blue in “The Historical Context of the Construction of the Vattai Fishing Boat and Related Frame-First Vessels of Tamil Nadu and Beyond,” published in Ships and the Development of Maritime Technology in the Indian Ocean (David Parkin and Ruth Barnes, editors; Routledge, 2016). The information and images in this post are from that article.

To quote Dr. Blue:
"Vattai, are flat-bottomed, have a box-like transverse section and are near wall-sided over much of their length. They range in size from around 13.72m long, with a beam of 2.13m and a depth of 1.37m, to the smallest vessels of c. 5.18m x 1.07m x 0.76m. However, irrespective of their size, they are all similar in shape with very high bows, and two or three masts each with a settee-lateen sail, a balance board, and, uniquely on this coast, leeboards."
The design process is of much interest. A single mould form or template is used to lay out most of the frames on a scrieve board, the form being flipped to draw the port and starboard half-breadths. (Forms for different boats differ from one another, apparently, only in the radius of the curve that joins their two straight, right-angled legs.) Since the boat’s cross-section (half-breadth shape) is constant across its entire midbody, a single shape drawn on the scrieve board suffices to define most of the frames, and this follows the exact shape of the form laid square to the edges of the scrieve board.

Use of mould form and scrieve board to design a vattai boat
Use of the mould form and scrieve board (A) to create the shapes of the "equal" frames for the midbody (B,C,D), and the progressively narrower frames toward the ends (E, F, G). 
Fore and aft of the “equal” frames that constitute the midbody, each of the next three progressively narrower frames at the bow has an identical counterpart in the stern. These frames that define the ends are derived from the same mould form according to a formula that defines how far in from the scrieve board’s upper edge and how far up along the diagonal the form is placed. By rotating and raising the form, different frame shapes may be drawn to create the narrowing and flare of the hull’s ends. The final three frames in the very bow and stern, however, are not drawn or gotten out at this time.

In the boat recorded by Blue, there were 15 “equal” frames for the midbody plus 12 “unequal” ones, evenly divided between the bow and stern. The midsection always consists of an odd number of frames – the central master frame, and equal numbers of identical frames fore and aft of it. The design can be readily made longer by the addition of more equal frames in the midbody with no changes to the ends, and made wider starting with a wider scrieve board but using the same mould form. Rules of thumb establish ratios between length, breadth, depth, and frame spacing, so the builder’s discretion to make changes is limited mainly to his choice of the mould form and number of frames.

Frames are built up from floor timbers and futtocks, which are assembled with “a complex dovetail joint” that “extends right through the turn of the bilge.” The vattai has no backbone, so apparently the frames are set up on the straight, flat bottom planking, which must be laid down first. Stem and sternpost are butted with a lap joint against the ends of the central bottom plank. The article states variously that the shapes of the very ends are determined by battens (ribbands) or by laid planking between the midbody frames and the end posts. Whichever is truly the case, these define the shapes of the three final pairs of half-frames at each end. Only in these final three sets of frames do the shapes of the vattai’s bow and stern differ. They are installed without floors, their lower ends overlapping fore-and-aft where they land on top of, or are notched onto, the stem and sternpost. (This detail can’t be determined from the drawing.)

I have been unable to find any other photos, descriptions or even references to the vattai through Google searches and would welcome additional input. There is much else I’d like to know, including:
  • whether the planks have a caulking bevel, and the materials (if any) used for caulking
  • the design process for the end profiles (i.e., whether the stem and sternpost shapes are determined by template or drawn by eye.) 
  • details of the rig and leeboards
  • details of usage: crew size, responsibilities, sailing procedures and performance

I would also much like to see additional photos. Google image searches for terms like “fishing boat Tamil Nadu” yield a number of stock photos of open fishing boats that do not appear much like the vattai (the distinctive bow shape is an easily-noticed identifying characteristic), and nothing else even close. Please communicate in the comments if you can add to the discussion.

Bundle Boats in Oman and Elsewhere

In the last week or so, two bundle boats from Oman came to my attention. First, a reader sent me a link to this travel article in Daily Kos, containing this photo:
Mangrove root bundle boat, Oman
Caption from original article: "This old, traditional, fishing boat is made from “barasti”, the aerial roots of the mangrove.  I took this shot on the beach near Sohar, the third largest city in the country located near the UAE border." (Click any image to enlarge.)
This brought to mind the following photo of a shasha, another Omani bundle boat, from Tim Severin’s The Sinbad Voyage, which I reproduced in a post several years ago. But unlike the boat in the Daily Kos photo, this one was made from palm fronds.

The very next day, an image of another Omani bundle boat, also apparently made of palm fronds, appeared in my Facebook feed. I found it surprising that, even in the present day and within the confines of a rather small country, two methods of bundle boat construction, based on different materials, remain in use.
palm frond bundle boats, Oman
Original caption: "These are fishing boats in Oman. They are filled with polystyrene and paddled out to sea. At night the catch is landed and the village builds bonfires to cook supper. Which is fish." (Posted by Jonathan Savill to the Facebook page Church of the Double-Bladed Paddle)

Bundle boats are not really boats: they are boat-shaped rafts that derive their buoyancy from the materials of their construction, which are themselves buoyant. In contrast, true boats achieve buoyancy enclosing air within a watertight shell (or, to phrase it another way, by excluding water from a watertight shell).

In most cases, bundle boats are made from soft, flexible materials like grass, rushes, reeds, or leaves, large amounts of which are wrapped with cordage into long bundles – generally pointed at both ends – and then tied to other bundles into a boat shape – i.e., pointed at the bow (and often, at the stern), and usually with something approximating either raised gunwales, also composed of bundles, or a cockpit formed by leaving a cavity in or between bundles.

Sticks, roots or branches may also be used for construction. In most cases, these are tied into bundles in a manner similar to that used for soft, flexible materials, but in others, they are arranged and lashed side-by-side and not truly bundled. This method reduces the craft’s buoyancy and freeboard, also reducing its payload and leaving the boatman’s bottom constantly wet, but it also reduces its weight and makes it easier to dry, probably prolonging its life.

Indigenous to parts of Africa, ambatch is a  large shrub or small tree with a lightweight wood. (Source: Hornell)
ambatch bundle boat, Angola
An ambatch canoe on Lobito Bay, Angola. In this example, the branches are not truly bundled, but are lashed side-by-side into a boat shape. This photo and the one above it are from Hornell's 1946 work, Water Transport: Origins and Early Evolution. I don't know if such craft are still in use.
Absent gunwales or a cockpit, a bundle-built craft would have no “inside,” and lacking this characteristic, it would be a stretch to to call it boat-like. But that’s hardly a firm definition. Some models of papyrus bundle craft from ancient Egypt lack “insides” but are so boat-like in shape that it is hard to deny them the name bundle boat. (The models do have very low bundle-built toe-rails, however, which approximate the function of gunwales in a minimal way.)

Somewhat similar reed “boats” remain in use on Lake Titicaca, although they have substantial bundle gunwales, and thus a definite “inside.” What most distinguishes these craft from Egypt and Lake Titicaca from the Omani, Upper Nile and Lobito Bay types shown above, however, is the large volume of the bundles in comparison to the load, placing the boatman and his cargo well above the water and giving fair promise of keeping him and his cargo dry.
Reed balsa boat, Lake Titicacas

The bundle boat was an technological dead end in the sense that it apparently never evolved anywhere into a true boat. Although stick-built bundle boats appear superficially to be a step in that direction, they are still solidly rafts in concept.

But technological evolution is not the sole measure of past or present validity. The fact that bundle boats remain in use in more than one culture in the 21st century testifies to their practicality and the soundness of the concept.

Bronze Age Carpow Logboat Moves to Permanent Home in Perth

We haven't had time for a post lately, so to keep the pump primed, we'll bring this recent news item to your attention, courtesy of The Courier.

The Carpow boat, a 3,000-year-old logboat excavated in 2006 from the River Tay in Scotland, was recently moved to a permanent home at the Perth Museum and Art Gallery. The 9.25-meter-long boat was recovered in generally very good condition, and it includes the transom board that closed in the stern. It is the second oldest logboat discovered in Scotland. Sadly, much of the bow is missing, but it is still one of the best-preserved Bronze Age logboats in Britain. This short video summarizes the excavation.



This next video shows the boat after conservation. The transom board is not in place, but you can clearly see the bosses that held it there, which were left standing on the inner surface of the boat when the trunk was carved out.

The Yathra Dhoni - A Single-Outrigger Ship of Sri Lanka

yathra dhoni beached
The large vessel is a yathra dhoni. Its outrigger allows it to sit upright on the beach without temporary supports (from Devendra, "The Lost Ships of Lanka.") (Click any image to enlarge)
Seagoing ships with outriggers are a rarity. If one defines “ships” as “(floating mobile nautical) structures which constituted significant elements in the economies of the societies which built and operated them” (Basil Greenhill, in The Earliest Ships: The Evolution of Boats into Ships), then a few of the larger traditional single-outrigger canoes of Oceania would qualify, but based on their size, burthen, and the fact that they are “canoes,” most modern observers would still call them “boats” without hesitation. Some motorized bancas of the Philippines might be (just) large enough to be thought ship-like by some, but no one of these double-outrigger vessels would qualify on the grounds of economic significance.

The yathra dhoni of Sri Lanka and the Coromandel Coast on India, then, may be the only traditional outrigger vessel that was undeniably a “ship.” Large and burthensome enough so as not to be mistaken for a boat, and used as a cargo carrier on both coastal and short oceanic voyages, the single-outrigger yathra dhoni (also spelled yatra dhoni, and also known as the maha-oruwa or maha oru, meaning “big outrigger canoe”) was in use for centuries – possibly thousands of years – and remained in common use into the early twentieth century.

Admiral Paris's drawing of a yathra dhoni
Admiral Paris's drawing of a yathra dhoni (from Essai sur la construction navale des peuples extra-européens ou Collection des navires et pirogues construits par les habitants de l'Asie, de la Malaisie, du Grand Océan et de l'Amérique dessinés et mesurés pendant les voyages autour du monde de "l'Astrolabe", "la Favorite" et "l'Artémise")
Outrigger ships in Sri Lanka were noted by Strabo (65 BCE-19 CE) and Pliny (23-79 CE), and if these were not yathra dhonies per se, they were probably their direct ancestors. A temple carving in Borobudur, Java, dated to the 8th to 10th century CE, shows “the arrival of Aryan emigrants to the Indonesian Islands” (Vitharana) in an outrigger vessel with features similar to the yathra. (The original Aryans, however, were from the area that is now northern India, not Coromandel or Sri Lanka.) Near the end of their history, yathras were known to be trading as far as the Moluccas, so their earlier use transporting Aryans or their neighbors to Java (which, like the Moluccas, is in Indonesia, but closer to India) seems credible.

Most yathras were 50 to 60 feet LOA with a main hull beam of 12 to 15 feet. The largest were 100 feet long with a 20 foot hull beam. Vitharana states that they were 10 to 15 feet in height, although it is unclear what points of measurement are implied. Cargoes ranged from 25 to 75 tonnes, with 50 being typical. The main hull was double-ended, with slack bilges, full midsections, and a slightly hollow entry.

Vosmer's drawing of Dodanduva yathra dhoni model
Tom Vosmer's profile drawing of the Dodanduva yathra dhoni model (from Devendra, "The Lost Ships of Lanka)
The outrigger varied in length, from about a third (Paris) to well over two-thirds (Vosmer’s drawing of a highly detailed model built in the former yathra center of Dodanduva, Sri Lanka, that is widely accepted for its authority) the length of the main hull. It was always mounted on the port side, fastened directly to substantial, downward-curving booms that extended right through the main hull at the level of the deck beams. (One simplified model exists with the outrigger to starboard, but this model lacks a rudder and may represent a different vessel type, or the difference may be due to imprecision on the modeler’s part.) Guys leading diagonally from the main hull to the outer ends of the outrigger booms helped stabilize the outrigger float fore-and-aft.

Dodanduva model of a yathra dhoni

The yathra’s rudder followed the curve of the sternpost. The rudder on the Dodanduva model is enormous and wide, but other reliable sources show rudders of more graceful shape and conventional proportions. From this, it appears that rudders were fitted in a range of sizes and styles. Vitharana refers to a “secondary rudder to act as a leeboard … in the region of the main mast touching the water on the starboard side,” but in no models or drawings that I know of does such a feature appear. A leeboard would appear to be unnecessary, since the hull was built on a keel that provided significant lateral plane to resist leeway. Some models and drawings also show a “gripe” at the bow and a skeg at the stern (upon which the rudder’s lower end was hung), both of which added to the lateral plane and directional stability.

Hornell's sketch of a yathra dhoni
Hornell's sketch of a yathra dhoni
The common rig was a ketch with square headed, loose-footed cloth lugsails and a jib on a bowsprit, said by Green to be “a rig common to the region of the Indian subcontinent.” Some smaller yathras may have had a single mast. Hornell’s sketch of the ketch version shows a second headsail inside the first one, apparently set flying, with its tack led to the port bulwark or possibly to the foredeck. Admiral Paris’s drawing shows a whisker pole holding out the luff of the mainsail. Standing rigging included shrouds, fore- and backstays, and a stay between the mastheads. According to Green, “The arrangement of the halyards was such that they prevent the mizzen yard from passing around the forward side of the mast. It must therefore be concluded that the mizzen sail on the yatra was never tacked, but went aback against the mast when occasionally on a starboard tack.”

Two bulkheads divided the hull into three sections: small bow and stern compartments, the use of which I have not found described, and a large cargo hold between them. Much of the deck was covered by a light, removable deckhouse roofed with split bamboo, leaving only narrow walkways along the sides for the crew to move fore and aft. Sliding cargo hatches were offset to starboard, and a simple cargo handling crane was located to port. In order for this to come in use, lighters – probably small dugout canoes – must have come alongside the main hull between the outrigger booms. But because the vessel would sit upright on a beach, supported by the outrigger, it may be that loading and unloading was often done on land. One assumes that the deckhouse roof was removed before cargo was handled.

The hull of the yathra was of a carvel construction using an unusual combination of stitched and nailed fastening. The planks, a minimum of 2” thick, were stitched to each other with coir rope and nailed to the frames with iron nails and roves. Accounts differ on whether the stitching holes penetrated straight through to the inner surface of the planks or exited on the plank edges. In any case, it is clear that the stitching served only to hold the planks against each other and not to the frames. Details on the order of construction are lacking, but one presumes that the planks were stitched first to make them tight, and nailed second. Joints were caulked with coconut husks and leaves inserted before the stitches were drawn tight.

yathra dhoni construction drawings
Vosmer's construction drawings of the Dodanduva yathra dhoni model (from Devendra, "Pre-Modern Sri Lankan Ships")
Stem and sternpost were fastened to the keel with hooked scarfs held with locking wedges. The frames and deck beams were few in number and widely spaced but of heavy scantlings, providing sufficient overall strength. Deck beams extended through the planking on both sides. Green says the frames were continuous from sheer to sheer, but given their scantlings and the hull’s shape, this seems impossible. Perhaps his information, which is not footnoted, stems from observation of a model which used continuous frames for expediency.

Tom Vosmer took careful measurements of the Dodanduva model, fed the details into a hydrostatics program, and found that the main hull, even without the outrigger, was “reasonably stable.” The outrigger, of course, significantly increased the vessel’s righting moment (by a factor of 100). It also increased drag, and therefore, the ship’s powering requirements. The rig, therefore, could have been smaller and simpler if the (still seaworthy) hull did not have an outrigger attached.

Yathra dhoni at anchor in Kalpitiya, Sri Lanka, 1913 (from Devendra, "The Lost Ships of Lanka") 
Yathras were mainly short- and medium-haul cargo vessels, serving ports large and small throughout Sri Lanka and the Coromandel Coast and making regular voyages to the Maldives (550 miles from Colombo, Sri Lanka), although they also sailed at least occasionally to the Moluccas (3,600 miles). Typical cargoes included textiles, rice, salt, fish and fish products, tea, and tiles. A large one carried a crew of 18.

The outrigger was always kept to windward except, perhaps, in the most benign conditions – an unusual and highly limiting practice for a tacking single-outrigger vessel. Working within these limits required coastal voyages to make use of the daily reversal of land and sea breezes: the vessel sailed only during the part of day when the prevailing breeze allowed the outrigger to be kept to windward. On longer voyages, the monsoon breeze dictated direction. This would have meant just a single round trip from Sri Lanka to the Maldives in any given year, whereas a vessel that could sail with either side to windward would be able to make several round trip voyages of that distance each year.

Most accounts tell of the yathra succumbing to competition from steamships around the turn of the twentieth century. Vitharana claims that 40 of them were still serving Dodanduva in the 1930s, but all other accounts tell of the last one being built there to some fanfare in 1930; that is was wrecked on its first voyage in the Maldives; and that that was the end of the tradition.

Vatican boat model exhibit, Part 3


This is the final post about a current exhibit of boat models and canoe paddles at the Vatican Museums. Previous posts about this exhibit cover the other models representing boats from outside the Western tradition, and one full-size canoe from the Solomon Islands. As noted in the previous posts, exhibit signage was sparse. We reproduce the English text of the exhibit cards in quotation marks. Our own comments appear in parentheses. As always, click any image to enlarge.

"Chile: Yaghan (Yamana) canoe" (Images created by Europeans show greatly different forms of Yaghan or Yamana canoes. See the Alakaluf canoe two images above.)
model bark canoe with full decks
"Canada: Canoe" (...and a rather fanciful one at that! We're not aware of any bark canoes built with full decks and a round cockpit coaming. The modeler seems to be combining aspects of the open bark canoe with the skin-on-frame kayaks of Alaska.)

"Mozambique: Raft" (We'd call this a coracle, not a raft, since it relies on the enclosure of space for buoyancy. The model is made from a single piece of bent bark. If the full-size boat is built the same way, it must be quite small, or else it requires an enormously wide tree.)
model outrigger sailing canoe, Africa east coast
"Africa - East Coast: Sailing boat with outrigger" (The main hull is extraordinarily narrow and highly rockered. This must be a thrilling boat to sail.)

Vatican boat model exhibit, Part 2

In a current temporary exhibit at the Vatican Museums, dozens of models of watercraft from numerous nations and cultures are presented to represent the diversity and interconnectedness of humanity. (See our previous post on this exhibit.) The models are displayed in glass cases (hence the poor quality of the photos that follow) with little explanatory material. 

We present our photos with the scanty information from the exhibit cards in quotation marks, and our own brief observations in parentheses. We invite readers to contribute additional information about any boat in the Comments. Only models representing craft from "outside the Western tradition" are included here. More images of other models from the exhibit will follow in a subsequent post. As always, click any image to enlarge.
"Japan: Sailing boat" (looks like it would be highly capable in surf)
"Indonesia: Sailing boat with outrigger" -- (actually two outriggers. Although the rig is set as a square sail, it appears to be hung asymmetrically on the mast and can probably be canted to form a kind of lugsail.)
"Philippines: Sailing boat with outrigger" -- (again, two outriggers. This is a banca, with a Western-style sailing rig.)
"Sri Lanka: Boat with fisherman" (We wonder if the model attempts to represent any real type of boat, or if it is purely fanciful, its shape dictated by the material available to the modeler. What's surprising and touching about this model is the paddler, who is modeled with a great deal of humanity.)
"India: Pirogue with rowers" (paddlers, actually)
"China: Boat for recreation" (and by that, we mean eating, drinking and sex.)
(background) "India: Pirogue with rowers" (again, paddlers in fact)
"Thailand: Royal boat" (identical exhibit cards for both models)
"China: Sea Junk" (The truncated bow and minimal rig are fascinating aspects of this model, which is certainly not meant to be an accurate representation.)
"Southeast Asia: River boat" (a sampan)
"China: Sea Junk with three masts"
"China: River boat"
"China: Dragon boat for racing"
(Nationality not identified)
Back row:
Left: "Raft for fishing with cormorants"
Center: "Houseboat with passenger and boatmen" (Error in labeling, as this open craft is clearly not a houseboat. The Italian label identifies it as a sampan with a passenger and a boatman)
Right: (label illegible in photo)

Front row: 
Left: "Houseboat with coxswain"
Center: "Houseboat with passenger and boatmen" (Error in labeling, as this open craft is clearly not a houseboat. The Italian label identifies it as a sampan with a passenger and a boatman)
Right: "Houseboat with fisherman"
"Samoa: Seven paddle canoe" (Noticeable similarities to a Samoan canoe in our post about Buckminster Fuller's model collection)
