Understanding Sailboat Heel: Dead Tiller, Balanced, and Excess Heel Explained #1260180 (License: Personal Use)

The diagram depicts a sailboat in three progressive heel conditions: 'Dead Tiller' shows the boat upright with no heel, indicating insufficient sail power or improper trim; 'Balanced' illustrates an ideal 15° heel angle where forces are optimized for speed and control; 'Excess Heel' demonstrates dangerous over-leaning that risks capsizing and loss of efficiency. Each state is labeled and visually distinct against a stylized waterline.

This image is commonly used in sailing instruction materials, marine safety guides, and beginner boating websites to teach fundamental boat dynamics. It serves users seeking to understand sail trim, balance, and stability-especially new sailors or students preparing for certification exams.
