33-552: Originally known as the Kallang River Reservoir, Singapore's second reservoir was impounded across the lower reaches of the Kalang River in 1910. In 1922, it was renamed Peirce Reservoir in commendation of the services of Robert Peirce, who was the municipal engineer of Singapore from 1901 to 1916. In late 1960s, due to increasing demand for water and the need to increase the capacity of Peirce Reservoir,

66-662: A 200-metre stretch of the Kallang River at Kolam Ayer a S$ 2.5 million facelift. The "demonstration project" by the National Parks Board (NParks) and the Public Utilities Board (PUB) is part of the Active, Beautiful and Clean Waters Programme to transform rivers and reservoirs into vibrant community hubs, and to get Singaporeans to cherish and take care of their waterways. NParks and

99-482: A capacity of 27.8 million m of water over 304 hectares of water surface. Upper Peirce Reservoir Park is a 5 hectares park beside the reservoir. Adding to its local scenery is the surrounding secondary forest which was protected as a water catchment area when the reservoir was built. This Singapore location article is a stub .

132-474: A common sight off the sea front even up to the 1960s. Today, this long, winding river has little or no industry except for a short distance, although a new industrial estate at Kallang Basin , near Kallang Bahru , has been built. The Pelton Canal ( Chinese : 佩尔顿水道 ) is a canalised river that flows from Ubi via MacPherson into the Kallang River in Kallang . It is one of the numerous tributaries of

165-639: A higher dam was constructed upstream of the existing dam at Peirce Reservoir in 1970. In 1975, a major water supply project to develop new water resources was undertaken to support Singapore's rapid housing and industrialisation programmes. A dam was constructed at the upper reaches of the Peirce Reservoir, forming the Upper and Lower Peirce Reservoirs. Upper Peirce Reservoir was officially opened by then Prime Minister Lee Kuan Yew on 27 February 1977. The fourth and largest reservoir of Singapore has

198-407: A jib. Most modern designs have only one sail, the mainsail; however, the traditional catboat could carry multiple sails from the gaff rig. Catboat is a charming and distinctive sailboat featuring a single mast with a single large sail, known as a gaff-rigged sail, and a broad beam that ensures stability. This type of vessel, named after the "cat" tackle used in sailing, has a rich history dating back to

231-431: A lot of weight in two "wings" which run sideways from the main part of the keel. Even more recent is the concept of canting keels , designed to move the weight at the bottom of a sailboat to the upwind side, allowing the boat to carry more sails. A twin keel has the benefit of a shallower draft and can allow the boat to stand on dry land. Multihulls, on the other hand, have minimal need for such ballast, as they depend on

264-411: A reduced draft, with a much reduced underwater profile. This, in turn, results directly in reduced wetted surface area and drag. Without a ballast keel, multihulls can go in shallow waters where monohulls can not. There are trade-offs, however, in multihull design. A well designed ballasted boat can recover from a capsize, even from turning over completely. Righting a multihull that has gotten upside down

297-523: Is a boat propelled partly or entirely by sails and is smaller than a sailing ship . Distinctions in what constitutes a sailing boat and ship vary by region and maritime culture. Although sailboat terminology has varied across history, many terms have specific meanings in the context of modern yachting . A great number of sailboat-types may be distinguished by size, hull configuration, keel type, purpose, number and configuration of masts , and sail plan . Popular monohull designs include: The cutter

330-489: Is difficult in any case and impossible without help unless the boat is small or carries special equipment for the purpose. Multihulls often prove more difficult to tack, since the reduced weight leads directly to reduced momentum, causing multihulls to more quickly lose speed when headed into the wind. Also, structural integrity is much easier to achieve in a one piece monohull than in a two or three piece multihull whose connecting structure must be substantial and well connected to

363-461: Is easier for a short-handed crew to manage. A yawl is similar to a ketch, with a shorter mizzen mast carried astern the rudderpost more for balancing the helm than propulsion. Traditional sailboats are monohulls , but multi-hull catamarans and trimarans are gaining popularity. Monohull boats generally rely on ballast for stability and usually are displacement hulls. This stabilizing ballast can, in boats designed for racing, be as much as 50% of

396-436: Is similar to a sloop with a single mast and mainsail, but generally carries the mast further aft to allow for a jib and staysail to be attached to the head stay and inner forestay, respectively. Once a common racing configuration, today it gives versatility to cruising boats, especially in allowing a small staysail to be flown from the inner stay in high winds. A catboat has a single mast mounted far forward and does not carry

429-606: Is the longest river in Singapore , flowing for 10 kilometers from the Lower Peirce Reservoir (originally named "Kallang River Reservoir") to the Kallang Basin . It originates in the planning area of Central Water Catchment , flows in a southeast direction through Bishan and Toa Payoh , before finally arriving in Kallang . Prior to extensive land reclamation along Singapore's southeastern coast,

462-421: Is the sloop, which features one mast and two sails, typically a Bermuda rigged main , and a headsail . This simple configuration is very efficient for sailing into the wind. A fractional rigged sloop has its forestay attached at a point below the top of the mast, allowing the mainsail to be flattened to improve performance by raking the upper part of the mast aft by tensioning the backstay. A smaller headsail

495-469: Is what prevents leeway and allows sailing towards the wind. This can be an external piece or a part of the hull. Most monohulls larger than a dinghy require built-in ballast . Depending on the design of the boat, ballast may be 20 to 50 percent of the displacement. The ballast is often integrated into their keels as large masses of lead or cast iron. This secures the ballast and gets it as low as possible to improve its effectiveness. External keels are cast in

528-702: The Geylang River and Rochor River . All these aforementioned waterways form part of the Marina Reservoir , as a result of the Marina Barrage . The Kallang Park Connector of the Park Connector Network (PCN) runs almost parallel to the Kallang River, providing a stretch of recreational space along the river. The Kallang Riverside Park straddles both sides of the Kallang River near the river mouth. In pre-colonial times,

561-530: The Marina Reservoir . A dam , the Marina Barrage , was built at the mouth of the Marina Channel at Marina South . With the completion of the Marina Barrage in 2008, the entire region comprising the basins of the Singapore River , Rochor River , Geylang River and Kallang River has transformed into a water catchment area. In April 2006, the Singapore government announced plans to give

594-552: The 19th century in the coastal regions of the United States, particularly New England, where it was widely used by fishermen and sailors. With its straightforward design and uncomplicated rigging, the catboat offers a straightforward and laid-back sailing experience, making it an ideal choice for beginners and pleasure sailors alike. Even today, catboats continue to be cherished by enthusiasts who appreciate their heritage and enjoy their picturesque appearance while cruising through

627-751: The Kallang River used to empty into the Singapore Straits at the Kallang Basin, near where Merdeka Bridge is standing. Today, the Kallang River flows into the open sea via the Marina Channel . Tributaries of the Kallang River include Sungei Whampoa, the Pelton Canal, and the Bukit Timah Second Diversion Canal. Other rivers that empty into the Kallang Basin, other than the Kallang River, include

660-486: The Kallang River. A section of the underground Kallang-Paya Lebar Expressway (KPE) follows the course of the Pelton Canal. Sungei Whampoa ( Malay for "Whampoa River", Chinese : 黄埔河 ) begins in Whampoa , near Jalan Rajah, and flows into the Kallang River in Kallang . The Bukit Timah Second Diversion Canal ( Chinese : 武吉知马第二分水渠 ) is a canalised river flowing from Whampoa to Kallang , following closely

693-757: The PUB reviewed some of the world's best rivers such as the Charles River in the United States and the Cheonggye Stream in Seoul to draw inspiration and learn best practices. By August 2007, the Kolam Ayer stretch of the river was transformed to include more greenery , floating decks, pathways and boardwalks for recreational activities. A water wheel was introduced as the centrepiece of

726-731: The aboriginal Biduanda Orang Kallang tribe lived in the swamps at the mouth of the Kallang River, and fished from their boats, seldom venturing out into the open sea. At the time of Sir Stamford Raffles landing in Singapore in 1819, half of the population of 1,000 were the Orang Kallang . Kallang River was also the place, where in the early days the Bugis traders from Sulawesi (Celebes) unloaded their cargoes of spices and tortoise shells , gold dust and slaves from their palari or their leteh-leteh . These sailing boats were

759-481: The bottom end in a receptacle that is supported above the keel of the boat or on the deck or other superstructure that allows the mast to be raised at a hinge point until it is erect. Some masts are supported solely at the keel and laterally at the deck and are called "unstayed". Most masts rely in part or entirely (for those stepped on the deck) on standing rigging , supporting them side-to-side and fore-and aft to hold them up. Masts over 25 feet (7.6 m) may require

792-513: The flow of rainwater so that downstream waterways have more time to drain. Bio-engineering techniques such as soil bioengineering and intensive hydraulic calculations were applied to create this. Besides slowing down rainwater, it now also offers residents a new recreational experience – soft planted river banks encourage people to get close to the water. 1°18′N 103°52′E  /  1.300°N 103.867°E  / 1.300; 103.867 Sailing boat A sailboat or sailing boat

825-536: The geometry of their design, the wide base of their multiple hulls, for their stability. Designers of performance multihulls, such as the Open 60's , go to great lengths to reduce overall boat weight as much as possible. This leads some to comment that designing a multihull is similar to designing an aircraft. A centreboard or daggerboard is retractable lightweight keel which can be pulled up in shallow water. On small sailboats, masts may be "stepped" (put in place) with

858-470: The hull itself has sufficient buoyancy to remain afloat. A multihull optimized for light weight (at the expense of cruising amenities and storage for food and other supplies), combined with the absence of ballast can result in performance gains in terms of acceleration, top speed, and manoeuvrability. The lack of ballast makes it much easier to get a lightweight multihull on plane, reducing its wetted surface area and thus its drag. Reduced overall weight means

891-450: The hulls. All these hull types may also be manufactured as, or outfitted with, hydrofoils . All vessels have a keel , it is the backbone of the hull. In traditional construction, it is the structure upon which all else depends. Modern monocoque designs include a virtual keel. Even multihulls have keels. On a sailboat, the word "keel" is also used to refer to the area that is added to the hull to improve its lateral plane. The lateral plane

924-573: The mainmast, but forward of the rudder post. The second mast is called the mizzen mast and the sail is called the mizzen sail. A ketch can also be Cutter-rigged with two head sails. A schooner has a mainmast taller than its foremast , distinguishing it from a ketch or a yawl. A schooner can have more than two masts, with the foremast always lower than the foremost main. Traditional topsail schooners have topmasts allowing triangular topsails sails to be flown above their gaff sails ; many modern schooners are Bermuda rigged. The most common modern sailboat

957-539: The path of the Pan Island Expressway (PIE). It joins the Kallang River near the traffic interchange at Whampoa Flyover. Other than those listed above, there is another unnamed Kallang River tributary in Toa Payoh . It flows from Braddell Road, via Toa Payoh North and Lorong 6 Toa Payoh, before meeting the Kallang River at Lorong 8 Toa Payoh. Kallang River is now part of the water catchment area for

990-401: The project. The water level was kept at a constant level — 3 metres deep — making activities such as kayaking and dragon boating possible. The upstream of the Kallang River is located at Bishan-Ang Mo Kio Park. Officially opened on 17 March 2012 by Prime Minister Lee Hsien Loong , the meandering river's capacity is now 40% more than when it was a canal. The river helps to slow

1023-399: The shape of the keel. A monohull's keel is made effective by a combination of weight, depth, and length. Most modern monohull boats have fin keels, which are heavy and deep, but short in relation to the hull length. More traditional yachts carried a full keel which is generally half or more of the length of the boat. A recent feature is a winged keel , which is short and shallow, but carries

1056-399: The waterways. A dinghy is a type of small open sailboat commonly used for recreation, sail training , and tending a larger vessel. They are popular in youth sailing programs for their short LOA , simple operation and minimal maintenance. They have three (or fewer) sails : the mainsail , jib , and spinnaker . Ketches are similar to a sloop, but there is a second shorter mast astern of

1089-720: The weight of the boat, but is generally around 30%. It creates two problems; one, it gives the monohull tremendous inertia, making it less maneuverable and reducing its acceleration. Secondly, unless it has been built with buoyant foam or air tanks, if a monohull fills with water, it will sink. Multihulls rely on the geometry and the broad stance of their multiple hulls for their stability, eschewing any form of ballast. Some multihulls are designed to be as light-weight as possible while still maintaining structural integrity. They can be built with foam-filled flotation chambers and some modern trimarans are rated as unsinkable, meaning that, should every crew compartment be completely filled with water,
