Power-Driven Vessel Underway T-Shirt – Navigation Lights Humor (Less Than 50m)

The Power-Driven Vessel Underway T-Shirt is inspired by COLREG navigation light rules — with a bold, humorous twist.

Featuring a detailed vintage-style maritime badge design illustrating:

• Starboard (Green)

• Masthead (White)

• Port (Red)

• Less than 50 meters in length

This design references the classic navigation light configuration for a power-driven vessel underway under COLREG rules. It’s instantly recognizable to deck officers, navigators, maritime students, and anyone who has memorized light combinations for exams — or midnight watch.

Perfect for:

• Deck officers

• Maritime academy students

• Captains & Chief Officers

• Navigation instructors

• Crew gifts

• Off-watch maritime humor wear

Soft, lightweight, and comfortable for everyday use, this T-shirt blends maritime knowledge with clever visual humor — a true insider piece.
