Navigation - Lesson 7 | Print |

Topic: Navigation Plotting Worksheets


This lesson is a student work session that allows students to apply all the skills they have developed from the previous lessons. 

US Navy using navigation skillsWorking in groups around a chart, they will solve a series of problems.  For the example provided, we use the 12283 Annapolis Harbor Chart, but you can use any local navigation chart to allow the students to learn and experience the waters in your local area."

After reviewing how sails generate speed for a sailboat, they will learn how to generate speed for their boat while also taking into account the many other factors affected by a boat’s sail area.

 

Lesson 7 - Sailboat Design Project

US Navy using navigation skillsAs a final exercise for the class, student groups will create a basic sailboat design and prepare a report that identifies the specifications of the boat and the data used to calculate those specifications. The report will also provide discussion as to the intended use of the vessel and why their design is optimally suited to that use, as well as a comparison to other boat types.

STEM Sailing™ - Navigation

The National Sailing Hall of Fame STEM Sailing Navigation on Land and at Sea Course is designed for 10th Grade high school students.

Each lesson includes a PowerPoint presentation and lesson plan. There are also handouts you can download and print for your students, including worksheets and exams.

 

 


Lesson 1 - History of Charts & Maps

Image from Lesson 1An introduction to charts and maps, whey they exist and their importance in our history and current life.

 

Lesson 2 - Deciphering Charts & Maps

Image from lesson 2Introduces students to learning how to read, decode, and decipher a nautical chart and topographic map.

 

Lesson 3 - Three Norths & Variation

lesson3Explains to students the differences in the three different ways to determine north. From this, they will be able to understand the concept and importance of magnetic declination or variation.

 

Lesson 4 - Magnetic Compass

lesson4Explains the science behind how a magnetic compass works and gives them the opportunity to practice taking bearings using a hand-bearing magnetic compass.

 

Lesson 5 - Bearing Triangulation

image from lesson 5Students will learn how to determine their location by triangulation. They will accomplish this by taking bearings of surrounding objects. This lesson will build on their work with the hand-bearing compass and demonstrate one of the primary uses of a compass.

 

Lesson 6 - Dead Reckoning

image from lesson 6Students will learn how to navigate by determining their expected future position based on current course and speed. After learning how to properly take a fix using both GPS and visual bearings, this introduces the concept of time, speed, distance, and direction.

 

Lesson 7 - Navigation Plotting

US Navy using navigation skillsThis lesson is a student work session that allows students to apply all the skills they have developed from the previous lessons.

 

Lesson 8 - GPS (with Exam Review)

image from lesson 8Students know how to use GPS, but will now learn how GPS actually works. Understanding the history and development of GPS is critical to allowing the students to look at the concept as an innovator or entrepreneur. Every day people are discovering ways to make our lives easier through GPS and this lesson aims to provide the students with a foundation behind the science.

Primary Goal: After this lesson, students should be able to determine the final piece of their sailboat design, the sails. After reviewing how sails generate speed for a sailboat, they will learn how to generate speed for their boat while also taking into account the many other factors affected by a boat’s sail area.

Lesson Objectives:

• Students will review how sails are able to generate lift, and thus speed

• Students will learn the importance of and how to calculate Sail Area

• Students will learn how to calculate Sail Area – Displacement ratio

Lesson Outline:

  1. Intro
    1. A sailboat uses her sails for propulsion by generating lift (upwind) or by blocking the wind and being pushed (downwind)
    2. Just like a sports car is interested in a high horsepower – weight ratio, sailboats use a similar type of measurement to determine the potential speed, or acceleration, of the sailboat
  2. Sail Area
    1. A sailboat’s propulsion comes from the wind on her sails and is proportional to the area of all the sailboat’s sails
    2. This is measured by calculating the area of a each of the sails and then simply adding those numbers together
      1. The measurement of sail area is calculated using square feet
    3. For more advanced courses you can discuss the measurements of E and P for the mainsail and I and J for the headsail
      1. It is also worth noting that actual sail measurements are more complicated because of the curvature shape of the sails
  3. Sail Area – Displacement Ratio
    1. In order to compare sailboats with one another, we use the Sail Area – Displacement ratio
    2. This shows how much power the sails generate compared to each pound of displacement
      1. Under this calculation, we are assuming that displacement is the sole limit of a boat’s speed due to the reasons discussed in previous lessons
      2. The calculation also involves dividing the displacement by 64. This is done because the weight of seawater is 64 lb/ cubic foot
    3. The higher the ratio indicates a high performance sailboat usually designed for racing
    4. Because of the large sail area, these boats are sometimes more difficult to handle and can become easily overpowered in high winds
      1. Low ratio – 8-13
      2. Medium ratio – 14-20
      3. High ratio – 21-40+

Exercises/Activities:

The actual calculation for Sail Area–Displacement is quite complicated. This is a great opportunity to give students practice using a scientific calculator. Also, the excel model provided can make quick calculations easier and can be used to check student’s work.
