This is a simple 1-bit memory, mechanical unit, that uses the position of the boat to store the on/off output. Pressing the button once, switches it on. Pressing it again, switches it off.

I got this idea from #gneruinseruihnutshnu, who suggested I try build one using minecarts.

I did not build this to try improve upon some redstone circuit. I actually have no idea what type of flip-flop this is. I was hoping a redstone expert could tell me, and also break down the Pros & Cons of how it compares.
