The Treader class Free Trader is a small civilian mercantile starship.


The Treader-class is a merchant vessel commonly encountered within the Distant Fringe region. It is classified as a Transport and is constructed as a conventional design. Similar designs have been in use from the time the Distant Fringe was first settled. Some believe that it was a further development of an ancient Solomani design.

Basic Ship Characteristics[edit]

Following the Imperial Navy and IISS Universal Ship Profile and data, additional information is presented in the format shown here. The small craft factor indicates the number of squadrons (of ten subcraft) carried on the ship. Tonnage on the universal ship profile is shown in kilotons (thousands of tons) where necessary. [1]

Basic Ship Characteristics [2]
#. Category Remarks
1. Tonnage / Hull The Free Trader is constructed using a 200 dTon hull built in a conical configuration. The hull is streamlined and has airfoil surfaces, giving good atmospheric performance that is reliant on its onboard gravitic systems.
2. Crew Total Crew Complement: x6

There are x6 Staterooms.

There are x10 Low Berths, primarily used for transporting livestock.

Accessible areas of the hull are fitted with grav plates and inertial compensators and have full life support and environmental systems.

  • There are internal monitoring and security systems throughout the vessel. Sections of the ship can be isolated in the event of an emergency.
  • There are multiple Emergency Lockers.
3. Performance / Engineering The vessel mounts a DeVoss-type Jump-2 drive, a Maneuver-1 drive and a Power Plant-2, giving performance of Jump-2, 1-G acceleration and producing 4 Energy Points. The ship has an agility rating of 1. The internal fuel tankage is sufficient for one Jump-2 and gives the power plant 4 weeks duration.
  • The engineering section has a main control room.
    • Ladders, gantries and platforms give access to the machinery.
  • The jump drive utilizes a hull grid.
  • The jump drive is fitted with a jump governor.
4. Main Section / Electronics Adjacent to the bridge is a Model/2 Computer: the vessel does not have a backup computer.
5. Hardpoints x2 hardpoints.
  • The listed battery groupings are considered standard for the class. Alternative battery groupings may be designated for specific routes.
6. Armament / Weaponry The normal weapons fit-out for a Treader is:

x1 triple Missile turret, firing as an independent battery.

7. Defenses The hull is unarmored.

x1 triple Sandcaster turret, firing as an independent battery.

The vessel is not fitted with screens or other passive defensive systems.

8. Craft / Subcraft The vessel carries no subcraft.
9. Fuel Treatment The vessel has internal fuel tankage of 44 dTons.
10. Cost The basic cost of the vessel is MCr104.700.
  • Both craft are standard designs. Detailed architectural plans are widely available and no design fee is chargeable.
  • If multiple examples of the design are ordered all of the ships in the production run qualify for a 20% discount, which reduces the price per unit to MCr83.760.
11. Construction Time 44 weeks (9 months) as standard.
  • Build times can be reduced by mass production and the efficiencies such processes generate, by increased financing, and by allotting additional yard resources and facilities to the construction contract.
12. Remarks Standard cargo capacity amounts to 80 dTons.

There is a 1 dTon secure locker.

History & Background[edit]

The Distant Fringe is said to be a far spinward-rimward area inhabited by colonists and refugees originating on Terra and separated by vast, almost uncrossable rifts that were once broached by a massive system of calibration points. Those few academics within Charted Space who have heard of the Distant Fringe regard it as little more than a tall tale. Likewise, many of the inhabitants of the Distant Fringe believe the existence of Charted Space to be mythical.[3]

These vessels are very rarely encountered outside of the Distant Fringe region. However, misjumps do occur and anomalies with bizarre spacetime and jumpspace effects exist: as such, craft of this type are not entirely unknown within Charted Space.[4]

The Treader class shares a basic hull pattern with the Wanderer class Luxury Yacht. The design is representative and a large number of variants exist, particularly with regard to the allotted weapons systems, onboard electronics, and the fit out of internal spaces.

Class Naming Practice/s & Peculiarities[edit]

A number of companies manufacture ships equivalent to the Treader class. They vary in hull shape and internal layout but all share the same basic design and all have very similar capabilities and performance characteristics.

  • Each variant class is named by the company that produces it: these organizations generally draw on traditional naming protocols. It is not uncommon for a historical class name to be reused.
  • Individual vessels within a class are issued specific serial numbers and transponder codes but traditionally are named by their owners. This is considered a serious affair and a ship with a frivolous name is considered "unlucky".
