1. Surfboard comprising:
a surfboard body extending along a longitudinal direction and having an upper surface and a bottom surface, an electrical battery pack being removably positioned in an upper compartment accessible from the upper surface, and an electrically driven water-jet configured to propel the surfboard and being provided with electrical power from the electrical battery pack, wherein the electrically driven water-jet is provided in a propulsion module being removably positioned in a lower compartment accessible from the bottom surface, wherein the upper compartment and the lower compartment partly overlap each other a distance as seen along the longitudinal direction, [ wherein the jet-propulsion module comprises a jet-box forming circumferential walls of a water channel, a directly attachable electric motor and an electronic drive module comprising circuitry for controlling the electric motor, wherein a drive shaft from the electric motor extends in rearward direction through a wall of the water channel and along and inside a rear portion of the water channel, wherein an impeller, a stator and a jet-cone are mounted rearward of the jet-box, wherein the stator and the impeller are dismountable in a rearward direction] .
7. Surfboard according to claim 6 [ 1, ] wherein the jet-box is made of heat-conducting material allowing heat to be transferred out away from the jet-box.
[ 17. Surfboard comprising: a surfboard body extending along a longitudinal direction and having an upper surface and a bottom surface, an electrical battery pack being removably positioned in an upper compartment accessible from the upper surface, and an electrically driven water-jet configured to propel the surfboard and being provided with electrical power from the electrical battery pack, wherein the electrically driven water-jet is provided in a propulsion module being removably positioned in a lower compartment accessible from the bottom surface, wherein the upper compartment and the lower compartment partly overlap each other a distance as seen along the longitudinal direction, wherein the upper compartment and the lower compartment partly overlap each other as seen along a height direction extending between the upper surface and the bottom surface of the surfboard, wherein the battery pack is directly connected to an electronic drive module of the propulsion module, wherein the jet-propulsion module comprises a jet-box forming circumferential walls of a water channel, a directly attachable electric motor and an electronic drive module comprising circuitry for controlling the electric motor, wherein a drive shaft from the electric motor extends in rearward direction through a wall of the water channel and along and inside a rear portion of the water channel, wherein an impeller, a stator and a jet-cone is mounted rearward of the jet-box, wherein the stator and the impeller are dismountable in a rearward direction, wherein the electrical battery pack is a replaceable and rechargeable water tight pack, wherein the electrical battery pack is provided with a first battery connector provided in and fixed relative to a lower wall of the electrical battery pack, wherein the propulsion module is provided with a second battery connector provided in and fixed relative to an upper wall of the propulsion module, the electrical connector being configured to be directly connected to the electrical battery pack.]
[ 18. Surfboard comprising: a surfboard body extending along a longitudinal direction and having an upper surface and a bottom surface, an electrical battery pack being removably positioned in an upper compartment accessible from the upper surface, and an electrically driven water-jet configured to propel the surfboard and being provided with electrical power from the electrical battery pack, wherein the electrically driven water-jet is provided in a propulsion module being removably positioned in a lower compartment accessible from the bottom surface, wherein the upper compartment and the lower compartment partly overlap each other a distance as seen along the longitudinal direction, wherein the jet-propulsion module comprises a jet-box forming circumferential walls of a water channel, a directly connectable electric motor and an electronic drive module comprising circuitry for controlling the electric motor, wherein a drive shaft from the electric motor extends in rearward direction through a wall of the water channel and along and inside a rear portion of the water channel, wherein an impeller, a stator and a jet-cone are mounted rearward of the jet-box, wherein the stator and the impeller are dismountable in a rearward direction.]
