Direct links #
stateDiagram Helm --> Direction Sail --> Propulsion Weight --> Balance
- The helm affects the direction:
- If I put my helm to the left or right, I luff or pull down.
- The sails affect propulsion:
- If I put a lot of sail area, I have a lot of power, I move faster.
- The weight of the crew affects the balance:
- If I put the weight on one side the boat heels more or less.
Indirect links #
The helm #
stateDiagram Helm --> Propulsion Bar --> Balance
- The helm plays on propulsion:
- If with my helm, I face the wind: I stop the boat.
- On the contrary, if I turn the boat so that the sails are inflated: I make the boat move forward.
- Using the helm generates a drag in the water which slows down the boat.
- The helm also affects the balance:
- If I use my helm to sail close-hauled: the boat heels.
- On the contrary, if I put the boat into the wind or downwind: the boat is flat.
The sail #
stateDiagram Sail --> Direction Sail --> Balance
- The sail plays on the direction:
- To knock down, I shock
- To luff, I tuck
- The sail also plays on the balance:
- If I tack, the boat heels
- If I ease off, the boat heels over
If several sails are present, it is possible to play with the balance of the two around the mast: the headsail will allow to bring down and the mainsail will allow to luff.
Dinghy at the head
To get this dinghy back to flat, you can either ease the sail or increase the recall.
The weight #
stateDiagram Weight --> Direction Weight --> Propulsion
- Weight plays into the direction:
- To shoot down, put the weight to windward and aft.
- To luff, you have to put your weight to leeward and forward.
- Weight also affects propulsion:
- Since the weight has an action on the direction, it has one on the propulsion.
- Depending on the placement, the weight allows a better upwind or downwind ride
Tilt-turn
The tilt tack and gybe are the first application of weight as indirect links, by making the boat heel, we force its direction by limiting the drag of the rudder
