A boat is a small watercraft propelled by paddle, oars, sail or motor. Boats have length not more than 30 m. Materials: wood, Plywood, fiberglass, aluminum, steel and polyethylene.

Pedal Boat

Basically boats are categorized into 3 types: a human power boat, sailboat and motorboat.

Human Power Boat
Boats powered by human move a cross water using paddle or row. At this time this boats mostly used for water sports and recreationally, such as canoe, kayak, dragon boat, rowing boat and paddle boat.

Canoe: small and narrow boat, at the bow and stern have taper shape and open on top. Generally, this boat has a length not more than 7 meters and can carry up to 8 persons.

Kayak: this boat is not different with canoe, kayak shorter than canoe and has a covered deck, carry no more than 2 persons

Sail Boat

Dragon Boat: This boat is similar with canoe but longer than canoe and at the front decorated with dragon heads. Dragon boat can carry between 10 to 50 paddles. Dragon boat only needs to use water sports and the national community Tong hoe.

Sailboat
A boat powered by wind driven using sail called sailboat.
Sailboats have 2 types differs based on the amount of mast, single mast and two masts. Sailing boat mostly used for water sports and sailing boat racing event.

Single mast
Sailboats with a single mast have relatively small size between 16 feet to 80 feet. This type of boat among other sloop, cutter and catboat

Sloop: this boat has single mast and supported by two sails, headsail on the front and mainsail attach to the mast and the boom.

Cutter: almost the same with sloop, only the location of the mast further back and having two jibs as well as a mainsail.
Catboat: these boats have a one mast and supported with one or two sails but without the jib.

Two masts
Sailboats using the two masts generally have length above 40 feet and usually used to offshore voyaging, such as ketch, yawl and schooner.

Ketch: These boats have two mast, main mast and second mast called mizzen mast. Mizzen mast has a size shorter than the main mast, main mast mounted at the front and mizzen mast at behind located in the front of rudderpost.

Yawl: This boat is almost the same with the ketch, only the mizzen mast located after rudderpost.

Schooner: usually have two masts, but can have more, despite having more than two-mast, the main mast which has a larger size.

Catamaran-Motor Boat

Motor Boat
Motor boat is a small watercraft powered by an internal-combustion or electric engine driven using propeller or impeller.

Motor boats driven using propeller have 3 types by the manner in which the engine is installed (power plan), the outboard motor, inboard motor and inboard-outboard motors (stern drive). Motor boats driven using impeller called jet boats. Jet Boats have 2 types differs by power plan: outboard motor and inboard motor.

Outboard Motor: the engine and propeller/impeller mounted outside on the back of the hull or transom.
Inboard Motor: the engine permanently mounted within the hull and, and propeller/ impeller passing through the hull.
Stern drive: the engine is contained inboard while the gear reduction and propeller are outside.

Hovercraft
Hovercraft or air cushion vehicle: a vehicle that can travel over land and water supported by a cushion of air that it creates by blowing air downward.

Small hovercraft are often used in physical activity,combustion, or passenger service, while giant hovercraft have been built for civilian and military applications to transport cars, tanks, and large equipment into difficult or hostile environments and terrain.

Airboat
An airboat is a flat-bottomed vessels propelled in a forward direction by an aircraft-type propeller and powered by either an aircraft or automotive engine. Airboats are a very popular in the Florida Everglades, and Louisiana Bayou, where they are used for fishing, hunting and eco-tourism.
