The only difference seems to be that the Muslim warships were, according to some Byzantine manuals, generally larger and slower than the Byzantine ones, perhaps indicating differences in construction, or the result of different types of wood being used. Like with the Byzantines, however, the terms adrumūnun and shalandī were often used interchangeably, along with the generic terms shīnī ('galley') and markab ḥarbi or asātīl ('warship').[164][165] Alternative interpretations consider the shīnī—which as a term appears relatively late and is particularly associated with the Levantine and North African coasts—a different, and larger, type of vessel than the common shalandī. The Ayyubid-era official and writer Ibn Mammati records that it had 140 oars, and featured a single mast with two to three lateen sails.[166] Unlike the warships of Antiquity, medieval Arab and Byzantine ships did not feature rams, and the primary means of ship-to-ship combat were boarding actions and missile fire, as well as the use of inflammable materials such as Greek fire.[167]
