Curriculum

The National Sailing Hall of Fame STEM Sailing Science of Sailing Course is designed for 10th Grade high school students.
Each lesson includes a PowerPoint presentation and lesson plan, plus handouts you can download and print for your students, including worksheets and exams.
This course will teach students about the components of a sailboat, how they work to propel the boat, and scientific factors that impact a sailboat's performance.

Students will learn how sailboat designs have evolved and improved over hundreds of years. They will also begin to understand why certain designs have succeeded and why others have failed.

Students will learn about the different forces on a boat and how they all work together. They will understand how sail aerodynamics affects boats with different designs.

After this lesson, students should be able to determine the proper hull designs necessary to compliment the various rigs.

After this lesson, students should be able to determine the proper hull designs necessary to compliment the rig they chose for the sailboat design. They will also understand the equations to make sure their boat is built within the necessary parameters to ensure seaworthiness.

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.

As 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.


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

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

Explains 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.

Explains the science behind how a magnetic compass works and gives them the opportunity to practice taking bearings using a handbearing magnetic compass.

Students 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 handbearing compass and demonstrate one of the primary uses of a compass.

Students 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.

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

Students 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:
 Intro
 A sailboat uses her sails for propulsion by generating lift (upwind) or by blocking the wind and being pushed (downwind)
 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
 Sail Area
 A sailboat’s propulsion comes from the wind on her sails and is proportional to the area of all the sailboat’s sails
 This is measured by calculating the area of a each of the sails and then simply adding those numbers together
 The measurement of sail area is calculated using square feet
 For more advanced courses you can discuss the measurements of E and P for the mainsail and I and J for the headsail
 It is also worth noting that actual sail measurements are more complicated because of the curvature shape of the sails
 Sail Area – Displacement Ratio
 In order to compare sailboats with one another, we use the Sail Area – Displacement ratio
 This shows how much power the sails generate compared to each pound of displacement
 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
 The calculation also involves dividing the displacement by 64. This is done because the weight of seawater is 64 lb/ cubic foot
 The higher the ratio indicates a high performance sailboat usually designed for racing
 Because of the large sail area, these boats are sometimes more difficult to handle and can become easily overpowered in high winds
 Low ratio – 813
 Medium ratio – 1420
 High ratio – 2140+

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.
