Fei Lun Jia Hai Zhou was a warship of unusual design, possibly a Ming-era throwback to older paddle wheel warships from the previous dynasties (as hinted by its tower ship-style crenellated superstructure). Intended as a capital-class warship despite its moderate size, Fei Lun Jia Hai Zhou was made of expensive and durable
nanmu wood and came with two masts, four inboard paddle wheels and twelve large oars. In addition, it also had two large slots at the bow and stern, which allowed two ships to be connected together via wooden beams into a
catamaran-like configuration for increased stability.

Tao Chuan Zi Mu Lun Zhou Chuan was actually not a different ship design per se, but a detachable exterior shell/auxiliary armour equipped by Fei Lun Jia Hai Zhou. Made of
Chinese fir, the exterior shell enclosed the warship from the front and both sides, and came with a bow fitted with barbed spikes and storage space filled with gunpowder and flammable materials. Beside protecting the warship from grounding hazards, the exterior shell was also a potent weapon in its own right, allowing the warship to ram into enemy ship, ignite the payload, then discard the shell to disengage.
