Electrofishing by boat. There are three types of electrofishers: backpack models, tote barge models, and boat mounted models, sometimes called a stunboat. [2] Backpack electrofisher generators are either battery or gasoline powered. They employ a transformer to pulse the current before it is delivered into the water.
If an electric boat has sails as well, and will be used in deep water (deeper than about 15 m or 50 ft), then a towed generator can help build up battery charge while sailing (there is no point in trailing such a generator while under electric propulsion as the extra drag from the generator would waste more electricity than it generates). Some ...
Battery balancing and battery redistribution refer to techniques that improve the available capacity of a battery pack with multiple cells (usually in series) and increase each cell's longevity. [1] A battery balancer or battery regulator is an electrical device in a battery pack that performs battery balancing. [ 2 ]

An electric vehicle battery is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). They are typically lithium-ion batteries that are designed for high power-to-weight ratio and energy density.
With drive train and lithium-ion battery provided by a California startup named Tesla, the second-generation ED with the second-generation 451 chassis was introduced in 2009 and made available in 18 markets around the world for leasing, or through the Car2Go carsharing service in selected cities, with over 2,300 units delivered.

As both the ship to be piloted and the pilot's own vessel are usually moving this may be dangerous, especially in rough seas. With outgoing vessels, a pilot boat returns the pilot to land after the ship has successfully negotiated coastal waters. [10] [11] [12] Pilots are required by law in most major sea ports of the world for large ships. [13]
The Pleasure Craft Operator Card (PCOC) is a document used in Canada as proof of competency to operate a recreational boat with a motor. [1] It is required for any craft fitted with a motor, even if the motor is not in use, for example an auxiliary motor on a sailboat. PCOC has been required since 1999.
Other duties vary, but the second mate is often the medical officer [2] and in charge of maintaining distress signaling equipment. On oil tankers, the second mate usually assists the chief mate with the cargo operations. The navigator's role focuses on creating the ship's passage plans. A passage plan is a comprehensive, step by step ...
