For many sailing craft 45° on either side of the wind is a no-go zone, where a sail is unable to mobilize power from the wind. Sailing on a course as close to the wind as possible—approximately 45°—is termed beating, a point of sail when the sails are close-hauled. At 90° off the wind, a craft is on a beam reach.
Burgos Wind Farm.It is currently the largest wind farm in the Philippines, providing 150MW of power to residents of Burgos, Ilocos Norte. Wind power in the Philippines accounts for a total of 443MW as of 2020 according to the Department of Energy, covering about 1.6% of the country's total installed capacity for both renewable and non-renewable energy sources.

Points of sail: the shaded area is the "no-sail" zone. Beating to windward on short (P1), medium (P2), and long (P3) tacks, each with a progressively wider corridor over the water. Sails are limited in how close to the direction of the wind they can power a sailing craft. The area towards the wind defining those limits is called the "no-sail zone".
APHC is committed to implementing the wind projects if the wind measurements and site-specific studies demonstrate that the power plants are commercially viable. [3] Phase 1 of this project is a wind farm in Barangay Halayhayin in Pililla, Rizal, Philippines. The wind farm is being undertaken by Alternergy Wind One Corporation. [4]
The Philippines being situated on the fringes of the Asia-Pacific monsoon belt, exhibits a promising potential for wind energy with 76.6 GW. [7] Wind power plants are the third most operated renewable energy source in the country. Solar Energy. In 2015, three solar farms were constructed in the Philippines.
The ancestral rig was the mastless triangular crab claw sail which had two booms that could be tilted to the wind. The sails were made from mats woven from pandan leaves. The triangular crab claw sails also later developed into square or rectangular tanja sails, which like crab claw sails, can be tilted against the wind. Fixed tripod or bipod ...
Sailing into the wind is possible when the sail is angled in a slightly more forward direction than the sail force. In this aspect, the boat will move forward because the keel (centerline), of the boat acts to the water as the sail acts to the wind. The force of the sail is balanced by the force of the keel. This keeps the boat from moving in ...
Sailing relies on the physics of sails as they derive power from the wind, generating both lift and drag. On a given course, the sails are set to an angle that optimizes the development of wind power, as determined by the apparent wind, which is the wind as sensed from a moving vessel.
