Single Main Hull
Building on our experiences from last year, we decided to forego the design of an air tight o-ring based central tubing. This is mainly due to the risk of detaching wires, and breaking circuitry, while opening the central tubing. We have now moved on to a more robust latch-on, latch-off system. All our electronics are encased inside one single hull, and the ease of removability of the roof of the sub makes sure no electronics get damaged in the opening process.
