I presume Chris R is looking at building a model of a traditional sailing dhow. Whilst the dhow is still used in the transport of goods there has been a massive revival of interest in sailing in the emirates in the last twenty or thirty years and the result has been the development of racing dhows. These are lightly built craft in three classes, 22ft 43ft and 60ft. They are long narrow craft built of wood with a large traditional lateen sail made in modern materials to power them, and power them they do. Large crews to 'sit them out'. From what I understand they have a long straight course set so that they are reaching all the way. I believe the 60footers have two masts. This form of racing has become very popular in the tourist areas with hotels sponsoring some of the boats.
I've been interested in these craft for some time and when I 'hopefully' manage to pull out of my present 'unwell' state, I shall finish my present project then seriously think about building one of these dhows. I'm sure it would be a most interesting project, particularly how she would handle under sail. I wouldn't bother with plans, a few photos, and as all they look like is an elongated racing dinghy, it shouldn't be difficult to build. Rigging too should not be difficult, though I have ideas about that to simplify. Anyway, we'll see.
