Roman Ship

A Roman Ship appears in Book 3 of the How to Train Your Dragon Book series, How to Speak Dragonese. A proper name for this ship is not given in the story.

Description
The Roman ship is not named, but appears to be under the direction of the Fat Consul and is utilized for "Dragon Rustling". It has an enormous cage aboard to hold captured dragons of many species, to be sent back to Rome for food and hides. It is a large ship, with many soldiers aboard, and, presumably, a ship's crew.

"It was, infact, a sizeable Roman ship, seventy meters long from stern to prow. The sails were pure white, and high above, when Hiccup craned his neck, he could see the Roman flag of the Imperial Eagle flapping cheerily in the wind."

How to Speak Dragonese
Hiccup and Fishlegs sail on the Sea-Known-As-Woden's-Bathtub in their small boat, The Hopeful Puffin as part of 'Board-an-Enemy-Ship' lesson in the Pirate Training Program. The Novices are to board a Peaceable fishing boat, menace the fishermen, and take a helmet as a trophy. They are knocked off course by Snotlout and the area is obscured by fog. Fishlegs becomes frightened by the possibility of being attacked by Sharkworms. He boards the first ship they come across without verifying what ship it is. It turns out to be a Roman ship, and Fishlegs is captured by Roman soldiers. Hiccup sneaks aboard, frees Fishlegs by releasing the captured dragons aboard, and escapes. However, Toothless is captured at the last moment, and looses half of his How to Speak Dragonese notebook to the Thin Prefect.
