Coins Cat #MakeItFloat

These objects were designed for the Thingiversity Science Challenge: Make It Float. The challenge consists of the creation of a 3D model of a boat or other floating object. To increase your chances of winning, 3D print your model and then test, redesign, and retest to optimize the amount of weight your boat can support using coins in your local currency, and this is our story:

The best an optimum solution for this contest is a box, with dimensions a multiple of the coin diameter, and as high as your printer limits. But a box is hard to push through the water...

But we wanted to reproduce a real ship for this contest, so we choose a catamaran (double hull ship) that could take the coins with style... and certain speed. The real ship is named Zephyr and is a wind turbine service catamaran, that is able to run at 26 knots.
A catamaran hull presents better speed and stability for carrying load (including coins). See our video of the prototype advancing in the water with a slightly
