The Vietnamese/Asian version of the coracle is made of interwoven bamboo and made water proof by using resin and coconut oil. [5] Oval in shape and very similar to half a walnut shell, the coracle has a keel -less flat bottom to evenly spread the load across the structure and to reduce the required depth of water; often to only a few inches.
Sailing into the wind is a sailing expression that refers to a sail boat's ability to move forward despite being headed into (or very nearly into) the wind. A sailboat cannot make headway by sailing directly into the wind (see "Discussion," below); the point of sail into the wind is called "close hauled".

Boating is the leisurely activity of travelling by boat, or the recreational use of a boat whether powerboats, sailboats, or man-powered vessels (such as rowing and paddle boats), focused on the travel itself, as well as sports activities, such as fishing or waterskiing.
The ICC is a product of the United Nations Economic Commission for Europe Inland Water Committee (UN ECE IWC) Resolution 40 (hereafter called Resolution 40). [3] This states that the ICC may be issued by a government of one state to its nationals and residents who may be on the waters of a foreign state, on condition that both accept the requirements and conditions set out in Resolution 40.
Boats and ships, which float by having the submerged part of their structure exclude water with a waterproof surface, so creating a space that contains air, as well as cargo, passengers, crew, etc. In total, this structure weighs less than the water that would occupy the same volume. [2]: 7–8
That power increases as the speed of the boat increases, allowing the boat to go much faster than the wind. Limitations to iceboat speed are windage, friction, the camber of the sail shape, strength of construction, and quality of the ice surface. Iceboats can sail as close as 7 degrees off the apparent wind. [4]
On a square rigged vessel with more than one mast, a number of options are available; these generally involve bracing round the square topsail on one or more masts to an aback position to counterbalance the sails that remain set in their normal position. [7]: 225–230 On a modern two-sailed sloop, there is only the jib and the mainsail.
2. (more precisely, as used in inland waters) to propel a boat with oars, where each rower uses just one oar. On inland waters, one person using two oars, one on each side of the boat, is termed sculling [35]: 135 rowlock 1. The cutout in the washstrake of a boat into which an oar is placed, so providing a fulcrum when the oar is in use. [47]
