A fender system consists of the fender (boating) itself, the panel, and the various hardware required to anchor and stabilize the unit. Fenders are made of a grade of rubber chosen for their flexibility. The more compressible, the more energy the fender can resist. They come in multiple sizes and shapes, aimed at handling different situations.
Holding ground is the area of sea floor that holds an anchor, and thus the attached ship or boat. [4] Different types of anchor are designed to hold in different types of holding ground. [5] Some bottom materials hold better than others; for instance, hard sand holds well, shell holds poorly. [6] Holding ground may be fouled with obstacles. [6]
Boat building is the design and construction of boats (instead of the larger ships) — and their on-board systems. This includes at minimum the construction of a hull , with any necessary propulsion, mechanical, navigation, safety and other service systems as the craft requires.
Reconstruction of a 19th-century naval architect's office, Aberdeen Maritime Museum General Course of Study leading to Naval Architecture degree Naval architecture, or naval engineering, is an engineering discipline incorporating elements of mechanical, electrical, electronic, software and safety engineering as applied to the engineering design process, shipbuilding, maintenance, and operation ...
A marine parachute anchor for a large yacht awaiting bagging up. A conical sea anchor with tripline (from an illustration in The Sailors Handbook by Halsey C. Herreshoff). An early wooden drogue. A sea anchor (also known as a parachute anchor, drift anchor, drift sock, para-anchor or boat brake) is a device that is streamed from a boat in heavy ...
Each arm must be rotated out manually; uses manila rope falls. Goose-neck shape to the arm that is swung out. [6] Mechanical (obsolete) – This type is like the radial davit, but both arms are moved out at the same time using a screw system; uses manila rope falls. An example is the Welin Quadrant davit type used on RMS Titanic. [6]
[a] [2]: 34–37 The design process saw the early adoption of the logarithm (invented in 1615) to generate the curves used to produce the shape of a hull, especially when scaling up these curves accurately in the mould loft. [1] Shipbuilding and ship repairs, both commercial and military, are referred to as naval engineering.
The design of anchor piles allows for three types of mooring configurations—vertical tethers, catenary moorings, and semi-taut/taut moorings—which are used for the mooring of offshore structures such as offshore wind turbines, floating production storage and offloading (FPSO) vessels, floating liquefied natural gas (FLNG) facilities, etc.
