Introduction: As sailboat designers know, the hull characteristics that keep a boat moving efficiently, resist handling difficulties and keep a sailboat upright, are sometimes in conflict.
Most modern sailboats give nearly equal attention to stability, load-carrying ability and a speedy hull, with perhaps a slight tilt toward one factor or another, depending on the designer's special aims. Sailboat hulls are designed to pursue a straight-ahead course with as little disturbance of the water as possible.
The portion of the hull shape that minimizes leeway is called either a keel or centerboard depending upon which is used in the design of the boat. NOTE: It is best to set up the tank outside the building, but it may be possible to have it inside. Ask students to suggest some considerations and goals for sailboat design (speed, stability, capacity). Introduce students to a variety of sailboat and sailing ship designs using books, magazines, and the internet.
Attach the sails to the masts, and attach the masts to the hull, making sure they all stay upright. In the testing tank, each boat will sail with a "following wind and following sea," and must sail straight without running into the shore or sinking. Each boat will have three trials to determine how much weight it can carry while still sailing at least six feet. Evaluation: Students should record the speed and distance sailed before the boat hits the side of the tank.

In the nearly "pure" racing sailboats, speed-producing elements are emphasized to the detriment of other factors. At the same time the boat is moving forward, wind pressure on the sails is pushing it to one side.
This fin-shaped feature in the bottom of the hull allows forward movement, but increases the side profile of the hull thereby increasing lateral resistance.
Support the boxes with books or large rocks where needed to withstand the pressure of the water when the tank if filled.

She has been lovingly maintained for the past eight years by an owner passionate about wooden boats. All boats, sail or power, are compromises, but sailing craft embody more trade-offs in their design than do other types. This lateral movement of the boat in the water is called leeway and is partially counteracted by the hull shape.

Students may want to design their boats so that the sails can be adjusted to control the effect the wind has on the sails and the direction the boat sails.
