The Coaster is a spelljamming ship built and used by groundling humans.


The Coaster is a groundling coastal trading ship, which is not intended for use in space. Sometimes used by those new to space travel, the Coaster makes a poor spelljammer. Coasters are very clumsy, suffering from poor maneuverability, and heavy handling which makes it difficult for a helmsman to operate. This results in a -1 penalty to SR (to a minimum SR 1). In addition, Coasters are poorly armoured, and require a large crew for their size. Most Coasters carry a single heavy weapon to deter pirates, however this is mostly for show, and the ship is very vulnerable to attack. Most spacefarers using a Coaster will upgrade to a more suitable spelljammer as soon as they can; assuming that they survive long enough.


When used as a spelljammer, a Coaster will typically carry a crew of about a dozen men. This is somewhat less than the 20 men which a Coaster usually carries when used as a sailing ship, but it is still more than the ship's air envelope can comfortably accomidate, making long journeys a poor idea.

Ship UsesEdit

Trader: Most Coasters in space are used as trading vessels. The only advantage that such a ship has over more capable ships designed for spelljamming is the fact that a Coaster can land in the water, and trade with groundling ports without attracting undue attention. In some of the safest areas of space using a Coaster as a trading vessel is actually a viable option; however, most of wildspace is not safe for the ship, and even in those areas that are safe a Caravel would be a better choice.

Other ConfigurationsEdit

Modifications to the Coaster are rare, since it is usually more cost-effective to simply purchase a better ship.
