Shore power or shore supply is the provision of shoreside electrical power to a ship at berth while its main and auxiliary engines are shut down. [1] While the term denotes shore as opposed to off-shore, it is sometimes applied to aircraft or land-based vehicles (such as campers, heavy trucks with sleeping compartments and tour buses), which may plug into grid power when parked for idle reduction.
A rip current is a horizontal current. Rip currents do not pull people under the water—they pull people away from shore. Drowning deaths occur when people pulled offshore are unable to keep themselves afloat and swim to shore. This may be due to any combination of fear, panic, exhaustion, or lack of swimming skills.
Shore power allows cruise ships to run on the electrical grid on land while docked, rather than running their own engines to produce electricity. When cruise ships use shore power, they can switch ...
Hydrodynamics is important to stroke technique for swimming faster, and swimmers who want to swim faster or exhaust less try to reduce the drag of the body's motion through the water. To be more hydrodynamically effective, swimmers can either increase the power of their strokes or reduce water resistance.
While the team success was perhaps a bit down compared to 2023, there were still plenty of standout individual performers.
It is similar to the swimming action of a frog or the leg action in the breaststroke style of swimming. [7] Frog kick involves the simultaneous and laterally mirrored motion of both legs together, approximately parallel to the frontal plane. The description assumes that the diver is trimmed horizontal and intends to swim horizontally.
Contrary to popular misunderstanding, a rip does not pull a swimmer under the water. It carries the swimmer away from the shore in a narrow band of moving water. [1] A rip current is like a moving treadmill, which the swimmer can get out of quite easily by swimming at a right angle, across the current, i.e. parallel to the shore in either ...
Basic diver training entails the learning of skills required for the safe conduct of activities in an underwater environment, and includes procedures and skills for the use of diving equipment, safety, emergency self-help and rescue procedures, dive planning, and use of dive tables. [146] [147] Diving hand signals are used to communicate ...
