The Model Shipways Sultana was the first wood ship model I ever built. I have extremely pleasant memories of it - a nice kit representing a beautiful little ship.
I should note that I built mine a long time ago. I know Model Shipways has updated the kit in many ways; I really don't know how different the latest version may be from the one I built back in the early seventies.
My understanding is that it comes with a machine-carved basswood hull. That means the hull is one piece of wood, "carved" by a lathe of the type used to make furniture legs. That process produces a basically correct shape, but has its limitations. The typical machine-carved hull has good, accurate lines, but components that are relatively thin are either omitted or deliberately made oversized. The modeler has to thin down the bulwarks, and add such parts as the keel, stem, sternpost, and rudder. A few rough spots generally need to be smoothed out, and the entire hull needs careful sanding. Such pieces as railings, wales, and moldings have to be made from the stripwood supplied, according to the plans. The process of building one of theses kits is quite different from building a plastic sailing ship kit. Not necessarily more difficult - but different.
To my knowledge, no machine-carved hull has pre-scribed planking detail. The deck planking is applied separately, generally in the form of basswood sheet with grooves scribed in it. Some modelers "plank" the exteriors of machine-carved hulls with thin strips of veneer. Most just paint the hulls in the appropriate colors. Plenty of experienced modelers argue that such a finish is preferable to out-of-scale planking grooves. It's a matter of personal preference.
Some of the more elaborate fittings (gun barrels and carriages, for example) are provided in the form of either brass turnings or britannia metal castings. (Britannia metal is an alloy of tin and brass. It looks and works pretty much like lead, but is far more durable - an excellent modeling material.) The masts and yards are provided in the form of dowels, usually with the basic taper turned in. I believe Model Shipways is currently supplying wood blocks and deadeyes with all its kits. (Bluejacket opts for britannia metal ones.) The kit is rounded out by several spools of thread and a set of plans and instructions. (Model Shipways is famous for the high quality of its plans.)
With the caveat that I haven't seen the latest version of the Sultana, I can recommend it with enthusiasm. This would be a great kit to break into wood ship modeling. If you do decide to order it, I recommend that you also order (from the same source, Model Expo) a copy of The Neophyte Shipmodeler's Jackstay, by George M. Campbell. This is an old classic book that Model Shipways published many years ago as an introduction to the building of wood kits based on solid hulls. It's well illustrated, very reasonably priced, and full of valuable tips on modeling. And anybody who memorized all the information in that book about sailing ships and their evolution would be well on the way to being knowledgeable about the subject.
Hope this helps a little. Good luck.
