HULLS

Hulls are rated by size (from 1 to 20). Each hull size has a set number of hatches and engine mounts. The length and diameter of a given hull can be increased or decreased as much as 25%, however, since two hulls of the same size can be of very different shapes.

Hatches always include an airlock inside the opening in the hull. The airlock provides an enclosed area that can be filled with air, allowing "spacewalkers" to take off spacesuits and then enter the ship. Hatches are located once every two or three decks, but there never is a hatch on the deck closest to the bow.

Engine mounts on a hull will take any type of engine. Chemical drives can be mounted in the tail. Ion and atomic drives must be mounted on struts. Note that a ship does not need to use all of its engine mounts; the engine mount number is simply the maximum number of drives the ship can carry.

Entries in the ADF/MR column show the ADF and MR that a ship of that size will have if it is outfitted with the maximum number of atomic engines its hull can carry. This is explained in more detail under Spaceship Drives.

HULL AVAILABILITY AND COST

Availability

Class I Centers. All types of spaceship hulls are available at Class I spaceship construction centers.

Class II Centers. Military hulls of type 6 or smaller, and hulls for civilian purposes of type 14 or less may be available at Class II spaceship construction centers. There is a 75% chance that a specific type of hull will be available.

EXAMPLE: A character at a Class II construction center wants a size 7 civilian hull. The player rolls d100 and gets 60. This is equal to or less than 75, so the hull is available.

Class III Centers. Class III construction centers can build only civilian system ships. Only 20 hull points of ships can be under construction at any one time. There is a 35% chance that a system ship hull of a specific size will be available at that Class III center.

Cost

The cost of a spaceship hull depends on the hull size and the type of center where the hull is purchased.

At a Class I center, the size of the hull being purchased is multiplied by 50,000 Credits. At a Class II center, the size of the hull is multiplied by 60,000 Credits. At a Class III center, the size of the hull is multiplied by 75,000 Credits. The price is higher at small centers because hulls are harder to build without major facilities. Hull prices are summarized on the Hull Cost Table.

HULL COST TABLE

Construction CenterCost Multiplier
Class I50,000 Cr
Class II60,000 Cr
Class III75,000 Cr

EXAMPLE: An assault scout hull (hull size = 3) costs 150,000 Cr at a Class I construction center. The same hull costs 180,000 Cr at a Class II construction center, or 225,000 Cr at a class III construction center. (The hull can be used only to construct a system ship at a Class III center.) The price for the hull is the same whether it is used for a system ship or a starship.
