Whats a Dhow

Good question. According to Clifford W. Hawkins, in his nicely illustrated book The Dhow: an illustrated history of the Dhow and its World, the term is mainly a European word that seems to encompass just about all of the medium and large indigenous sailing craft of the Indian Ocean, including those of Arab, Persian, and Indian derivation, and more lately including motor-sailing and pure power craft as well. Even before 1977, when the book was published, Hawkins interviewed dhow sailors throughout its range, and none of them used the term and few even knew it; and those who did were familiar with it only through their contacts with Westerners.

Now lets look at the typical "triangular" sail of a dhow:

Notice how the dhows sail is really a quadrilateral, with a short luff or leading edge, whereas the feluccas have a true triangular sail with no luff. This sail is called a settee, not a lateen. On some dhows this is very easy to mistake because the luff angles down only slightly from the line of the sails head, but its there nevertheless, and most easily recognized by the fact that the spar does not extend all the way to the tack or front-bottom corner.

But since both square-sail types are now extinct, cant we revert to the definition with the settee sail? No again, as a look at the thoni, an Indian type, shows at the top of the post. This thoni is flying an extraordinary diversity of sail types, including a settee main; a gaff spanker on the mizzen called a kose; a bome pai brailed up below it on the boom; a thanni or "water" sail hanging from the bowsprit; a settee-shaped topsail called a towser; a komitti, a rafee sail that appears just forward of the towser, flying from a stay; and a big four-sided jib called a dastoor that seems to have its upper forward corner ("throat"?) supported by a sprit or some other sort of yard. I believe theres at least one more sail flying on the mizzen but its covered entirely by the mainsail.

Bottom line, we probably cant come up with an iron-clad definition of a dhow, since it is a term that Europeans applied to just about all the sailing craft of the Indian Ocean, encompassing different rigs, hull forms, construction methods, and uses, and hailing from many different and far-flung lands and cultures. Best to think of dhows like seagulls -- there aint no such bird as a "seagull," but its a convenient cover-all term nonetheless and, even if you cant define it, most people know the group of birds, or boats, that youre talking about when you use it.
