Rule of Thumb: what is the recommended deviation for compass and rudder on either side?

Explanation:
Keeping your heading close to the intended course is the key. The rule of thumb is to hold the compass course within about five degrees of the target and make only small, incremental rudder adjustments to stay there. This small tolerance accounts for the ship’s inertia, sea conditions, and minor compass deviations, so you don’t chase the needle with big, abrupt turns. If you let the deviation creep past five degrees, you’ll drift more, need larger corrections, and the ship can become unstable or uncomfortable to steer. Larger tolerances like ten, fifteen, or twenty degrees would allow noticeable off-course drift and more aggressive steering later on, which is inefficient and harder to manage. So five degrees is the practical sweet spot for smooth, controlled steering.
