My other hobby is model boats, My passion tug boats, I built this one last year, working navigation lights, complete with bow thrusters twin steerable 58mm props with 60mm steerable Kort nozzles, working smoke funnels. All run with twin 700 brushless motors on 12 volts with an 11:1 planetary gearbox.

I have just finished a submarine the hardest part is setting the dive mechanism, Basically, there are two ways to submerge a boat: dynamic diving and static diving. The boat submerges by filling the main ballast tanks with water. After that, the buoyancy is accurately adjusted with the trim tanks. Once underwater, the depth of the boat is controlled with the hydroplanes.
