Circular supersmelter

Hello everyone, I have designed a circular supersmelter that uses floating chestboats as the distribution method. Those chestboats are pulled by a main boat that goes in a circle on an ice track. The boats go in a circle roughly every 10 seconds, thus ensuring every furnace is used at all times. Only one item is in the furnace at any given time, thus ensuring an efficient spread of materials. The chestboats floating is very important to the design, as this allows them to go the same speed as the puller. The puller is above and a bit offset to the boats. This ensures they float and that they can clear the corners. A second puller boat is required to reach all the boats. The second puller boat is pulled by the main boat. This supersmelter is designed to work with fuels that have at least 200 ticks burn time. It features 408 furnaces, 1224 hoppers, 9 chestboats and 9 bunnies. The bunnies are used so you open the chest by default and not enter the boat. It can smelt and deliver a doublechest of materials in ~110 seconds. The theoretical minimum for 408 furnaces to smelt a doublechest would be ~85 seconds assuming no item transfers, so this design is close to the theoretical limit. It features a manual mode and an automatic mode that stops the boats once there are no more items to distribute. The logic of the automatic mode is designed to collect all the smelted items before stopping the boats You need to load and unload the chestboats yourself, as any other method would have slowed down the design. You can smelt less than a doublechest if you want, just make sure to load fuel in the boats adjacent to the input boat. The automatic mode is designed to work with both input boats. This design is not 100% fuel efficient as there are a few ticks where a furnace is empty. This was a deliberate choice as it would have made the design somewhat more complicated. It can probably be done, but I don't think it is that important. I recommend having a 1:1 fuel to input material ratio. The worst that can happen is you load too much fuel in the furnaces. Another important aspect is that the loop cannot be exactly 10 seconds with this design (it has to be ever so slightly longer). This is because the output hoppers cannot pull and push items in the same tick. You could get around this by having a dedicated track for the output boats with it's own slime launchers or by delaying the output boats with a longer boat chain. The amount of furnaces is limited by how much ground the puller can cover in 10 seconds. In the upcoming Chaos Cubed update it can probably be expanded by using a sulfur cube as the puller, as they can move a lot faster. This would mean lower times to smelt a full double chest. You can use less than 408 furnaces as long as you keep the 10 second loop by delaying the puller boat. This can be done at any of the slime launchers in the corners. This ensures that the automatic mode still works as intended. This design uses 3 hoppers per furnace. The output could be collected by hopper minecarts, so you use only 2 hoppers per furnace, but it would probably be slower.
