Table of Contents #3.3 The operator is able to:
A: Maintain directional control at minimum control speed... B: while keeping the boat on a predetermined course for a distance of at least five boat lengths.
Understanding the Element
• This is an important skill since many situations arise when an operator needs to maneuver a powerboat at a very slow speed while maintaining control of the boat. For example, achieving the slowest possible speed is necessary when approaching a dock, slip, or ramp, coming alongside another boat, or operating in congested traffic or a buoy/ anchorage field.
• “Minimum control speed” is different from idle speed (see Appendix D for definition of terms).
Designing Instruction • Directional control involves helm, gearshift, and throttle adjustments to keep the boat on a predetermined course. The techniques vary by type of boat and power. For example, for twin-screw inboards, use of the gearshifts alone while keeping the wheel centered may be the most efficient method.
• Practice use of coordinated helm, gearshift, and throttle controls before introducing the maneuver. • Emphasize turning the helm in the appropriate direction before shifting into gear. • To maintain a predetermined course, the operator could utilize a fixed object to steer toward.

Proficiency description
The operator: Keeps boat on a predetermined course for a distance of at least five boat lengths under minimum control speed. Maintains predetermined course within 10°. Steers smoothly and adjusts for wind and/ or current. Maintains proper lookout throughout the entire maneuver.
The operator: Keeps boat on a predetermined course for a distance of at least three to four boat lengths under minimum control speed. Maintains predetermined course within 10°. May oversteer, requiring over- correction at times. Does not adjust heading for wind and/or current. Maintains proper lookout throughout the entire maneuver.
The operator:
Is unable to keep boat on a predetermined course for at least three boat lengths at minimum control speed. Maintains predetermined course more than 20°. Oversteers most of the time. Does not maintain proper lookout throughout the entire maneuver.
