🔍 Key Concepts

• Review common stability and trim plan symbols used on ship plans and curves of form. • Think about how naval architects often abbreviate or combine letters to mark the ship’s centerline on drawings. • Notice how some symbols visually resemble the initial letter(s) of the word they represent.

💭 Think About

• Look closely at symbol #5 and ask: does it look like a stylized combination of any of the option words’ first letters? • Which of the four choices is most commonly labeled on almost every ship’s plan or midship section drawing? • Would displacement, leverage center, centerline, or counterflood limits normally need a simple, easily repeated marker across many plan views?

✅ Before You Answer

• Compare symbol #5’s shape carefully to the letters in the word you think it represents — focus on C and L first. • Recall from your stability and construction studies which items are routinely drawn as a vertical reference line through the ship. • Before choosing, eliminate any terms that are usually shown as numbers, curves, or areas rather than a small graphic symbol.
