A port tack, in kitesurfing and sailing, is a state where the wind is coming from the left side of the direction of travel. In kitesurfing, it refers to riding with the left hand forward.
According to the basic right-of-way rules on the water, a rider on a port tack must yield to a rider on a starboard tack (where the wind comes from the right).
Etymology of “Port”
The origin of the term comes from the structure and docking methods of ancient ships. Early ships did not have a central rudder but instead had a steering oar (the “steer-board,” which became “starboard”) mounted on the right side. To avoid crushing and damaging this vital steering board against a dock, ships would always moor with their left side facing the port (wharf). As a result, the left side of the vessel itself became known as the “port” side.
Port Tack Start
In racing, there is a tactic known as the “port tack start.” While most competitors line up on the starting line on a starboard tack to maintain right-of-way, a rider using this approach deliberately starts on a port tack. It is extremely risky as the rider must avoid all other competitors, but it offers the advantage of securing a favorable upwind line by exploiting wind shifts on the starting line. Furthermore, it can reduce the number of tacks required to reach the upwind mark and allows the rider to quickly grab clean air away from the congested fleet, making it a highly effective strategy in certain situations.
