Jongkong
A jongkong is a type of dugout canoe from Maritime Southeast Asia. "Jongkong" was the simplest boat from Riau-Lingga area, and can be found widely though in small numbers throughout the area. The first record of "jongkong" comes from the Malay Annals (which was composed no earlier than the 17th century AD), being used by Majapahit empire during the first Majapahit attack on Singapura (1350) and during the fall of Singapura (1398). Etymology. The name comes from two words, that is "jong" and "kong" or "jegong". "Jong" means a boat or sampan, no matter large or small, while  kong or "jegong" is the place where masts are set up to hold the sail. Thus the name can be translated as a sailing boat that is used by the coastline community. Description. In this region it is essentially a small, inshore boat and it is rarely built to a length of more than about 12−14 feet (3.7−4.3 m). It is typically a one-man boat, with a length of 9−10 feet (2.7−3 m), with depth at the mid-section about 10−12 inches (25.4−30.5 cm). It consists of a dugout base, with the hull spread slightly, and the sides built  up by the addition of a single plank. Larger versions have a small triangular sail, and smaller versions are usually propelled by a short, single-bladed paddle or rarely by a double-bladed paddle.
