Haha you're dedicated. I was just joking but I guess a gram here and there makes a difference for you. Keep up the good work

Weight is very important for the entire project. The weight needs to be approximately 450g or else it won't work as expected. The battery weighs 70g (or 15% of the total weight). That 15% needs to be placed where the center of mass is neutral. All things need to be considered. Consider a situation where the center of mass is 1cm to the right of the center of buoyancy.. It will want to rotate to the right. Even a real jet ski is very close to being neutral.. They lean slightly to the right when water fills the exhaust tube, but when underway that water evacuates and it becomes neutral. Think how much that thing wants to roll if you are traveling 10mph and you place your weight on the bondrail. This kind of puts everything into perspective at this scale. Offset the weight towards the front some and it will submarine. I added rocker just in case.
I looked up titanium and it needs to bent at high temperature. At room temperature it has a ton of springback and it weakens considerably if tried to be bent.
