I stitute of Naval Research, Beiji g 100073, Chi a) Abstract: Based o the equatio s gover i g the motio of the ship a d three dime sio s equatio s of the towed cable system, the o li ear towi g system dy amic model of the towi g ship a d towed ship co ected with cable is established by matchi g both the positio s of the towed poi t of ship a d the e d poi t of cable. For evaluati g the relatio ship betwee course stability a d tra sverse stability of the towed ship, the four degree equatio s of the towed ship is used i the towi g system dy amic model. For the research o regular waves i flue ce o the motio s of the towed ship, the wave actio force a d mome t o the ship is also i troduced. The towi g ship motio is simulated by steeri g rudder us i g co trol rule of PD, so the motio of towi g ship u der steeri g rudder is calculated truly for simulatio . For o e towed system that i cludes o e towi g ship of 5 000 to s a d o e towed ship of 3 000 to s co ected by towi g cable, its motio s are simulated by usi g the o li ear tow i g system dy amic model established i this researc
