Question 71 Deck General
70% to passTo get the best speed when tacking and using a mainsail and jib, how should the sails should be trimmed?
A
With as much of a gap as possible between the two sails in order to catch the most wind
B
Trimmed so that an air slot is formed between the two sails
C
With one sail set as close to a right angle as possible to the other
D
Trimmed so the jib is on one side of the vessel and the mainsail on the other
AI Explanation
The correct answer is B) Trimmed so that an air slot is formed between the two sails. When tacking and using a mainsail and jib, the sails should be trimmed to create an air slot between them. This allows the wind to flow smoothly between the two sails, maximizing their efficiency and providing the best speed. The air slot prevents turbulence and disruptions in the wind flow, which would occur if the sails were trimmed too close together (option C) or on opposite sides of the vessel (option D). Option A, leaving a large gap between the sails, would not provide the optimal aerodynamic interaction between the two sails.
