Sail shape - Outhaul, Downhaul and Boom Vang

Quest: Position @ wheel station is too close to wheel
At the Wheel station, the wheel is too close to the player. I have to look down, and hold the controller awkwardly to grab the wheel and steer. I compared the same stationary guardian with Big Breezy Boat and the position is much more comfortably back from the wheel. Both pictures were from the same sitting position; I just switched from 1 game to the other. L - Marineverse Cup, R - Big Breezy Boat.
Controller input mapping
Allow players to map different buttons on controllers to different functions in the game. For example right joystick could be used for locomotion, jib or mainsail.
