This design utilizes a “pontoon style” assembly of the barrels which is the most efficient way to maximize floatation and minimize drag. To offset the weight of our shelter, we would fill the barrels on the opposite end with water. Since each barrel has a maximum buoyancy of ~450lbs. and a 20ft raft would […]

Barrel Raft Design Round 3

After some internet research, I decided to sketch out my idea for the barrel raft. I was reading about flow dynamics and hydrodynamics to see which principles we should include to maximize our flow rate. Flat stern is our powerhouse of motion, we need to maximize the flat surface area increasing the amount of push. Pointed […]
