The Egyptian Aiyassa

Continuing our observations from The Last Sailors: The Final Days of Working Sail by Neil Hollander and Harald Mertes, let's look at the Egyptian aiyassa, which is not at all related to the boats of ancient dynastic Egypt. The aiyassa is the characteristic big bulk carrier of the Nile, and when the book was published in 1984, there were still thousands of them in commercial use. Hollander states that the hull form was based on the Portuguese galleass (from which the word aiyassa is derived), and so strictly speaking, I shouldn't be addressing it, as it's from the Western tradition, but one look at the huge lateen rig, and I think that most readers will cut me slack.

Anyway, Hollander's aiyassa is a big boat for a river sailing craft -- the big ones weighed in at over 100 tons. They sported huge lateen rigs, with the tip of the boom soaring 100 feet in the air. They also carried a mizzen -- the word for the mizzen, by the way, being the same as in English, since it was an Arabic term to start with. The mainsail rig weighs close to a ton, and in The Last Sailors, it took four men a half hour to raise it, using tremendously crude machinery. In the author's observation, everything aboard was in a constant state of disintegration, and this is borne out by Mertes' photos, which show every bit of the rig pieced together with innumerable, horribly unshipshape knots and splices. There is no pride of seamanship or sentiment here -- the boat being viewed simply as an inexpensive tool with which to do a job.

Aiyassas carry bulk goods like hay and bricks. In 1984, the upriver (i.e., southbound) trade in finished goods had dried up, being overtaken by road and rail transport, so the boats would travel upriver empty, and only return to Cairo with cargoes. They would sail south on the prevailing breeze, and drift north with the current, essentially out of control, moving astern, abeam -- however the current wished to take them. Extremely beamy, the craft are regularly loaded to the utmost limits of their capacity, so that they ride with mere inches of freeboard. Since they're drifting downstream when laden, there seems to be little or no chance of heeling and shipping water over the gunwale, but in the "old days," when they ran upriver laden and under sail, this may not have been the case. They are, however, extremely beamy, providing a great deal of heeling resistance, even with their huge rigs.

Most boats, it seems, were owned by small merchants in Cairo, in fleets of a few boats. Crews were paid $114 a month, which I interpret as meaning the salary not for individual crew members, but the whole crew. (On the boat described, there were four crew members, including the captain.) Even in 1984, they were being displaced by diesel-powered, steel-hulled boats called sandals, and now I can't find anything about aiyassas by Googling, or on Wikipedia. Hard to believe they've disappeared not only from the river but also from the written record, so I have to presume that they're also known by another name, whether or not they're still in use. Can't even find photos by Googling "Nile Sailboat"-- only lots of photos of feluccas, which are much smaller craft. If anyone can point me to a good photo that I could borrow without infringing somebody's rights, please let me know and I'll post it here.

Finally, don't be misled by the ancient Egyptian boats in the links below -- they are unrelated to the aiyassa, but pretty interesting nonetheless.

Jangadas Again

Do check out the April 1 post on jangadas at http://rowingforpleasure.blogspot.com/ . Nice photos, and very nice Brazilian music with more jangada photos in the YouTube clip.

I had meant to discuss just a couple more details of the jangada's rig in my last post, but the subject got away from me, so here they are:
  • The upper end of the mast is apparently very flexible: it appears bent severely back in every photo I've seen, and I presume that the bend is put there by tension on the mainsail's leech.
  • The loose-footed sail is huge, but since it's made of muslin, it probably lets a good deal of wind through. The Jangadieros carry a carved wooden scoop with which they throw water on the sail to swell the fibers and make it a bit less porous to the wind.
  • Most or all of the sails have advertisements printed on them. According to Hollander, savvy marketers in Brazil, who recognize the value of such a picturesque, tradition-laden image, provide the jangadieros with the sails for free.
All for now.
