What are boats? Boats are vessels that vary in size and can float and travel on water. Small boats are found in the lake while larger ones are used for other purposes. There are three types of non-motor boats, sailing boats and motor boats. The first and oldest boat was the log boat or dugout canoe. It was made from a hollowed out tree trunk. The oldest salvage boat was the Pesse canoe. The first boat built on planks came from Egypt. The Egyptians created three types of boats, the reed raft was used for hunting, the wooden boats were faster and more stable than rafts and were used for transportation and the last one is the papyrus boat, it was similar to the boats of wood but was shaped like a papyrus to keep royalty and gods. These boats were used as funerals and burials. The Uru is a wooden ship built in Beypore, southwest India. This vessel was used by the Arabs since ancient times as a merchant ship. Urus is still produced in Arab nations. They are made of different types of wood and the main one was teak. The teak was sourced from the Nilambur forest. A yacht is a boat powered by an engine. They also vary in different sizes and classification. There are two yachts, one sailing and one motor. They were used by the Dutch navy which caught pirates on the ship. Yachts were made of wood until 1950 but over the years they used aluminum, steel and veneers. They also use it for sports and leisure. It has been an international sport since 1851. Yachts are used for holidays and cruises. Materials Boats Are Made Of Boat builders use many materials to build the actual boat and many techniques as well. One technique is "Sew and Glue" construction. Uses high quality marine plywood, simple sutures, f...... paper halves ...... food/epoxy are strips of wood veneer (a thin layer of wood) layered diagonally l 'relative to each other and protects against moisture. It is glued together with marine grade epoxy. Wood-Core/Epoxy is a wood core which is often balsa wood because it is very light and is covered on the outside with a layer of fiberglass. The main problem is abrasion by other hard objects and has a long service life. Plywood is only popular with some builders because it is quick and easy to build. It is quite expensive and not always available, but it is strong and heavy. It must be protected from any type of moisture and must be painted for protection. The main problem is humidity but it is quite easy to replace damaged parts. There are many other types of materials used by boat builders, but I can't find them all. The ones I have given are the ones most commonly used by boat builders now.
