Direct drive, in which an actuator is attached to the steering quadrant, at the top of the rudder stock inside the boat. This is the least intrusive method of installation. Wheel mounting, in which a motor is mounted near the steering wheel, and can be engaged with it when in use. This typically involves either a belt drive or a toothed gear ...
A mass-produced radio-controlled yacht In 1898, Tesla demonstrated a radio-controlled boat (U.S. patent 613,809 —Method of an Apparatus for Controlling Mechanism of Moving Vehicle or Vehicles). A radio-controlled boat is a boat or ship model controlled remotely with radio control equipment.
Winch. A grinder is a crew member on a yacht whose duties include operating manual winches (called "coffee grinders") that raise and trim the sails and move the boom. [1] It is a physically demanding role with a significant impact on a racing yacht's overall performance.
A footy sailboat. The Footy is a very small (usually) radio-control sailboat whose length is a mere 12 inches (30.5 cm). The hull can be made from a fiberglass mold, 3D printed or simply with thin sheets of plywood or even depron fitted together. Two servos are used, one to control the sail and one for the rudder. These are the smallest remote ...
[3] [4] The snubbing winch is used to pull vehicles out of mud, snow, sand, rocks, and water, and to pull vehicles through or over obstacles. The winch is made of cable made up of a braided synthetic rope, or a steel cable wrapped around a motorized drum. Each is controlled electronically, allowing the operator to control the winch speed.

The boat has a draft of 4.75 ft (1.45 m) with the standard keel. [1] For sailing the design is equipped with a halyard winch console, with vertical cleats to secure the halyards. The design rules limit the adjustable backstay, the boom vang and the mainsheet to a maximum of an 8:1 mechanical advantage.
Hydraulic piston vangs are used on larger sailboats and controlled by manual or electric hydraulic pumps. [2] By controlling leech tension, the boom vang is one way of controlling sail twist. [3] The boom vang may also be used to flatten the mainsail on dinghies. [4] On small sailboats and some cruising sailboats a vang may be omitted.
