The following tables are based on information found at http://digilander.libero.it/anno1503/ and http://www.a-pianto.ch/Englisch/e_Anno1503/e_Index.htm . Some of this information exists in the in-game help, but the statistics seem to have been mixed up - for example, Swordsmen are listed as "Damage: 1 Square, Range: 8", which does no sound particularly logical.

"Cargo" indicates number of cargo holds. Each hold can contain up to 50t of one item. "Unit" shows the number of ground units than can be carried. War machines with an assigned crew count as a single unit. One Scout (including mule) likewise counts as a single unit. "Cannon" is the maximum number that may be mounted. Upkeep costs of all ships are included under military expenditure.

Ship speeds are increased in the expansion - original values are given.
