Abstract
A control handle for controlling an electric drive system of a sailboat is provided. The control handle comprises a handle and a handle shaft, where the control handle is provided with a plurality of engagement positions. A first engagement position is adapted to engage a forward drive mode of the electric drive system, a second engagement position is adapted to engage a reverse drive mode of the electric drive system, a third engagement position is adapted to engage an idle drive mode of the electric drive system, and a fourth engagement position is adapted to engage a hydro energy generation mode of the electric drive system.

A control handle for controlling an electric drive system of a sailboat, where the control handle comprises a handle and a handle shaft, where the control handle is provided with a plurality of engagement positions, where a first engagement position is adapted to engage a forward drive mode of the electric drive system, a second engagement position is adapted to engage a reverse drive mode of the electric drive system, a third engagement position is adapted to engage an idle drive mode of the electric drive system, wherein the first engagement position is reached by rotating the handle in a first direction from the third engagement position, and the second engagement position is reached by rotating the handle in a second direction from the third engagement positionwherein a fourth engagement position is adapted to engage a hydro energy generation mode of the electric drive system, where the fourth engagement position is reached by moving the handle in a first longitudinal direction on the handle shaft, and in that the control handle further comprises a locking position in which none of the engagement positions can be changed, where the locking position is reached by moving the handle in a second longitudinal direction on the handle shaft.
Method for engaging an electric drive system of a sailboat in different drive modes, a generation mode, or a locking position in which none of the engagement positions can be changed, where the modes and locking position are set by the use of a control handle comprising a handle and a handle shaft, comprising:
- engaging the electric drive system in an idle drive mode when the handle is in a third engagement position,
- engaging the electric drive system in a forward drive mode by rotating the handle in a first direction from the third engagement position,
- engaging the electric drive system in a reverse drive mode by rotating the handle in a second direction from the third engagement position,
- engaging the electric drive system in a hydro energy generation mode by moving the handle in a first longitudinal direction on the handle shaft, and
- engaging a locking position by moving the handle in a second longitudinal direction on the handle shaft.
