This defines the boat's tacking angles upwind, gybing angles downwind, and is useful for long distance navigation routing (a combination of both). If the polar data is stored in a lookup table or formula onboard, the boat could calculate it's most efficient heading. The polar plot can be created by relating the apparent wind angle (AWA), apparent wind speed (AWS) and speed over ground (SOG). To create the polar plot, the boat needs to be sailed in varying wind conditions at different headings. Maximizing VMG results in the shortest time to get to a target. In effect, it is usually more efficient to steer a precise zig-zag path.Ĭreating a polar plot for our boat would allow us to determine which direction the boat should point in order to achieve maximum VMG. For sailboats, it is very rare that a direct heading (ie sailing directly towards your intended target) has the best VMG. VMG is the distance traveled in the direction of a target. Polars are most useful as a means of quantifying a boat's best possible velocity made good (VMG). It is important to note that a polars are a best case scenario they assume flat water, constant wind speed and good sail trim. Altering the rig, hull and keel design will vastly change the polars of the entire boat. The further away the line is from the center, the greater the possible speed.Ī boat's polars are typically created one of two ways: data collection or computational. The graph on the left shows the wind coming from the top of the graph, each of the lines spiraling out from the boats position represent the optimal speed available at the corresponding angle. Since the boat will be using information in the form of angles and magnitude, the polar coordinate system might be able to simplify calculations. Instead of using (x,y) coordinates, the polar coordinate system uses an angle and distance away from the origin. Polar coordinates are just another way to represent points on a graph.

THE FOREST WIKI SAIL SAILBOAT MOD
This marks the first episode that Cameron Boyce becomes the permanent voice of Jake due to a change in Colin Ford's voice. In collaboration with Souldrinker, we proudly present a map mod for the ModAPI.Then the Wise Old Parrot tells Skully that he is giving his old ship (the Leaky Beak) to him. When the whistle is blown, the Parrot Guards lift up Hook and carry him away. When they open Wise Old Parrot's treasure, it turns out to be a whistle to call the guards of Skybird Island. Izzy uses pixie dust to fly up to the Leaky Beak and flip the switch back. But Hook accidentally hits the switch that opens the wings, and the ship starts to fall. Suddenly, Hook and Smee arrive and steal the Leaky Beak. Wise Old Parrot tells Skully that he used to own the Leaky Beak.
When they bring it to Skybird Island, they see Princess Winger and the Wise Old Parrot. They make it to Never Ever Peak Mountain and find the treasure. When Hook learns about this, he wants the map sail, but to everyone's surprise, the ship has wings and can fly. The crew sees that the map leads to a treasure on Never Ever Peak Mountain, which was meant to go to Skybird Island. When the crew lets the sail loose, they find a treasure map on it. Skully calls his new ship The Leaky Beak. Captain Hook, who is nearby, laughs and says: "That pitiful pile of planks will never be a ship, it's barnacle bait." That makes Skully feel bad, so Jake and the crew decide to fix up the old ship and give it a new coat of paint. The young pirates think it is perfect for Skully. It is a small, wrecked ship, with a bird figurehead on the front. Jake and his crew are sailing toward Never Land, when something on Shipwreck Beach catches their eyes. Jake and his crew discover a treasure map stuck on the sail of a shipwrecked boat on Shipwreck Beach.
