In a 1994 review Richard Sherwood notes that the, "Dolphin is a lateen-rigged cat board boat, slightly longer than most. Capacity for reasonable sailing is two adults." [2] Randle B. Moore wrote about the design in 2011, saying, "the Dolphin Senior is one of many small sailboats patterned after the world's most produced boat, the Sunfish.
Excessive ship motions may hinder the vessel's ability to complete its mission such as the deployment and recovery of small boats or aircraft. A measure of an individual's ability to complete a specific task while on board a moving ship is the motion-induced interruptions [ 2 ] (MII).
An Ultra Light Displacement Boat (or ULDB) is a term used to refer to a modern form of sailboat watercraft with limited displacement relative to the hull size (waterline length). Principally manufactured from the mid 1970s through mid 1980s, these boats generally sit higher in the water allowing them to move faster in nearly all water types ...
The Trophic State Index (TSI) is a classification system designed to rate water bodies based on the amount of biological productivity they sustain. [1] Although the term "trophic index" is commonly applied to lakes, any surface water body may be indexed. The TSI of a water body is rated on a scale from zero to one hundred. [1]
Evaluation of Water Quality Using Biotic Index Values [3] Biotic Index Water Quality Degree of Organic Pollution 0.00 - 3.50 Excellent No apparent organic pollution 3.51 - 4.50 Very Good Possible slight organic pollution 4.51 - 5.50 Good Some organic pollution 5.51 - 6.50 Fair Fairly significant organic pollution 6.51 - 7.50 Fairly Poor
Lightweight displacement – LWD – The weight or mass of the ship excluding cargo, fuel, ballast, stores, passengers, and crew, but with water in the boilers to steaming level. Loadline displacement – The weight or mass of the ship loaded to the load line or plimsoll mark. Deadweight tonnage (DWT) is a measure of how much weight a ship can ...
RNLI inshore rescue boat during Falmouth Lifeboat Day, August 2006. A rigid inflatable boat (RIB), also rigid-hull inflatable boat or rigid-hulled inflatable boat (RHIB), is a lightweight but high-performance and high-capacity boat constructed with a rigid hull bottom joined to side-forming air tubes that are inflated with air to a high pressure so as to give the sides resilient rigidity along ...
