From Loren Wiseman's website:
The ship's boat is a small vessel ordinarily carried to perform odd jobs and minor operations for a larger ship or deep space installation. This book contains five variants on the same basic design, and includes deckplans (scaled at 1/2" = 1.5 meters) and game ratings for Classic Traveller, MegaTraveller, and GURPS Traveller.
In addition to the standard, unmodified ship's boat, this book details:
The lifeboat variant, carried by such starships as the Bastien-class subsidized Liner, and equipped with emergency low berths for 48 passengers.
The System Transport variant, used for short trips within a star system.
The VIP variant, used to convey nobles, executives, or high government officials in comfort and style.
The ramshackle Belter variant, used for deep space prospecting among the planetoid belts of hundreds of star systems.
