2. Crab claw sail - Wikipedia

   en.wikipedia.org/wiki/Crab_claw_sail

   The crab claw sail is a fore-and-aft triangular sail with spars along upper and lower edges. The crab claw sail was first developed by the Austronesian peoples by at least 2000 BCE. It is used in many traditional Austronesian cultures in Island Southeast Asia , Micronesia , Island Melanesia , Polynesia , and Madagascar .

3. Austronesian vessels - Wikipedia

   en.wikipedia.org/wiki/Austronesian_vessels

   The crab claw configuration used on these vessels is a low-stress rig, which can be built with simple tools and low-tech materials, but it is extremely fast. On a beam reach, it may be the fastest simple rig. Another evolution of the basic crab claw sail is the conversion of the upper spar into a fixed mast.

4. Fore-and-aft rig - Wikipedia

   en.wikipedia.org/wiki/Fore-and-aft_rig

   Fore-and-aft rigged sails include staysails, Bermuda rigged sails, gaff rigged sails, gaff sails, gunter rig, lateen sails, lug sails, tanja sails, the spanker sail on a square rig, and crab claw sails. Fore-and-aft rigs include: Rigs with one mast: the proa, the catboat, the sloop, the cutter; Rigs with two masts: the ketch, the yawl; Rigs ...

5. Rig (sailing) - Wikipedia

   en.wikipedia.org/wiki/Rig_(sailing)

   Lateen rig features a three-sided sail set on a long yard, mounted at an angle on the mast and running in a fore-and-aft direction. Crab claw sail (also known as Oceanic sprit or Oceanic lateen) features a three-sided sail with spars on both the foot and the head. It's either mastless, supported by a "prop", or mounted on removable or fixed masts.

6. Mast-aft rig - Wikipedia

   en.wikipedia.org/wiki/Mast-aft_rig

   A mast-aft rig is a sailboat sail-plan that uses a single mast set in the aft half of the hull. The mast supports fore-sails that may consist of a single jib, multiple staysails, or a crab claw sail. The mainsail is either small or completely absent. Mast-aft rigs are uncommon, but are found on a few custom, and production sailboats. [1]

7. Tanja sail - Wikipedia

   en.wikipedia.org/wiki/Tanja_sail

   The sail might be a derivative of the older Austronesian triangular crab-claw sail. It developed from the fixed mast version of the crab-claw sail and is functionally identical, with the only difference being that the upper and bottom spars of the tanja sail do not converge into a point in the leading edge.

8. Lashed-lug boat - Wikipedia

   en.wikipedia.org/wiki/Lashed-lug_boat

   The lashed-lug technique remains remarkably homogeneous throughout the entirety of the Austronesian range. The keel and the base of the hull is a simple dugout canoe.Planks are then added gradually to the keel, either by sewing fiber ropes through drilled holes or through the use of internal dowels ("treenails") on the plank edges.

9. Outrigger boat - Wikipedia

   en.wikipedia.org/wiki/Outrigger_boat

   They had no central rudders but were instead steered using an oar on one side. The ancestral rig was the mastless triangular crab claw sail which had two booms that could be tilted to the wind. These were built in the double-canoe configuration or had a single outrigger on the windward side.
