Table of Contents
Minimum control speed. The slowest speed at which an operator can effectively control the heading of the boat using intermittent application of power, steerage and headway.
Navigation rules. Rules for the operation of a boat while on the water, whether underway or at anchor, and designed to prevent collisions.
Neutral. The engine/propulsion unit are not in gear or engaged.
Normal operating speed. The speed at which the boat is operated for optimum performance and efficiency. The actual speed is dependent upon design of the hull (see Planing Speed).
No-sail zone. The zone in relation to the wind where the sails cannot generate power; sometimes called the “no-go zone.” Novice. A person who is new to an activity and typically has little or no knowledge or skills related to that activity.
Objectives. Specific end results students will achieve that collectively accomplish the overall goal for the unit of instruction. They provide guides to selecting content, designing the instructional strategy and preparing the materials to engage students in the instructional activities.
On-water instruction. A course or program of instruction that is boat-based and on the water for skills development and assessment. Instruction takes place primarily in the natural setting of the boat (on or near the water) with experiential/ active learning as the primary method of delivery used by instructors.
Outhaul. A line used to tension the foot of the mainsail. Passengers. Any person on board, excluding the operator.
Performance Objectives. Specific focused outcomes to be achieved as a result of engaging in a learning experience. Objectives may identify the concrete knowledge, skills, attitude or behaviors a student will be able to demonstrate as a result of the learning experience.
Planing speed. On hulls capable of planing, the speed at minimum RPM needed for the boat to remain on plane.
Planing stop. The stop used to bring a planing hull to a stop with the least amount of movement or advance along its original track while avoiding having water enter the boat over the transom. This applies only to planing hulls.
Point of sail. The direction a boat is sailing relative to the wind. There are five points of sail: Close-haul (or Close- hauled), Close Reach, Beam Reach, Broad Reach, and Run (or Running).
Porpoising. The motion of the bow of a boat bobbing up and down due to its fore and aft trim and resulting interaction with the water. Not wave generated. Port. 1. A harbor; 2. the left-hand side of a boat when facing forward.
Prerequisites. Something that is required before a student can participant in a learning experience. For example, a prerequisite for attending a course might be a previous learning experiences attended, a set of skills previously acquired, or knowledge previously learned.
Proficiency. A description of the behaviors and actions that demonstrate the level of competence, accomplishment or skill in operating a recreational boat.
Program. A collection of courses designed to accomplish a comprehensive set of goals and objectives too large to be accomplished by any one course of instruction.
Propulsion unit. The mechanism that causes the powerboat to move (e.g., propeller, jet). The phrase is applied to a mechanical device rather than a sail or paddle.
Radius of turn. The distance a boat offsets laterally during 90° of turn; usually measured in feet, yards, or meters. Rate of turn. The change in vessel heading per unit of time, typically measured in degrees per minute.
Rubric. A mechanism used to define and describe distinct levels of proficiency for a particular skill in behavior and action. Along with distinguishing successful from unsuccessful demonstration of a skill, rubrics identify performance that needs improvement to obtain targeted successful level of proficiency.
Rudder. The movable appendage attached to a boat under the water and with which it can be steered. A rudder could be attached to a post underneath the boat or hung on the transom with fittings called pintles and gudgeons.
