Assumptions: -All calculations assume air is of negligible mass Design goals: -Maximize hydrodynamic efficiency -Build a boat straight from the imagination -Create a boat that can actually be 3D printed successfully Design explanation: -From some basic research on hull design, multihull boats gain many advantages over monohull boats, such as increased stability and improved speed. http://www.sailingissues.com/yachting-guide/catamarans.html Final Design Calculations: Total boat volume= 10172.3717 mm3 => 101.72 cm3 Mass of boat=107.82 g Force of gravity on boat=1056.67 mN Hull volume (just plastic) = 8992.8251 mm3 => 89.93 cm3 Void volume in hull = 3573.6095 mm3 => 35.74 cm3 Total hull displacement = 125.7 cm3 Buoyant force due to hull (assuming air is of negligible mass) = 1231.57 mN Assuming quarters have a mass of 5.670g, the boat could theoretically hold 30 quarters safely Dimensions: Hull length = 9.3 cm, large hulls 5.08 cm, small hulls -Boat hull comments: Assembly: -Haven’t had a chance to print the full design, but the hull and bottoms can be attached together
