The Revolutionary Army had prepared three models of merchant ships. These three models referred to three different sizes: large, medium, and small merchant vessels.
The small merchant ships were somewhat like electric cars, used for short-distance commuting across this vast, boundless sea, and their prices were set very low.
There was no need for this twin-dial setup to use electricity. The entire merchant ship was equipped with two Wind Dials: one was mounted atop the mast to absorb wind energy, while the other hung behind the sail, blowing fiercely to provide propulsion for the whole ship.
These small cargo ships allowed small merchants to travel freely between smaller islands, fully solving the problem of supplying daily necessities to islands that major merchants were unwilling to visit.
They were somewhat like the bicycles or small vans Leo used when traveling to the countryside in the past. These ships thoroughly solved the problem of "the last nautical mile."
This medium-sized merchant ship was the vessel before Luffy and the others. Coincidentally, its specifications were extremely close to those of the Thousand Sunny.
The ship was roughly fifty meters long and fifteen meters wide, using a dual power system of electricity and wind energy.
When powered by electricity, it could reach a speed of thirty knots. At the lookout tower atop the mast was a moderately sized wind turbine, which could use sea winds to store electricity and help the ship sail for longer periods.
