Hello everyone, as someone interested in this cool little hobbies, I have some questions regarding the rules of construction, specifically rule 8. As well as just a general question No water belts, double hull areas, watertight compartments, or other construction techniques may be used to defeat this rule. This rule is clearly aimed at creating water tight air pockets. But I can't help but but think, why not use the same compartment scheme as titanic (never thought I'd say that)? This is not an air tight compartment, and would not prevent sinking. However it would prolong the life of a sinking ship that would normally sink bow or stern first. By allowing water to flood one compartment at a time. A small water channel underneath would allow some water to get to a pump, so you aren't just holding a bunch of water. A bit dodgier, but adding a bulkhead that does not go all the way to the bottom, would not be water tight, but in the event the ship begins to lean towards the bow or stern it could trap air. Furthermore, gyroscope and a counter weight? Why do you all use CO2 when compressed air would be easier to fill, and you could cut a huge amount of weight by using a ninja super light. Air is also just lighter than CO2.
