Sketched on paper and in CAD possible designs and determined approximate length and width dimensions.
Collaborated with Land and Water groups to discuss design.
Purchase a used boat hull for a reasonable price and modify it.
Install a support frame/structure with crossbars around the rim of the hull to minimize wear and weight on the thin aluminum of the hull.
We will also need to drill holes through the hull for the axles for Land mode.
A top priority of ours will be to properly seal any holes we drill in the hull so that the vehicle does not take on water.
Build it as hydrodynamic as possible to maximize speed in water.
Attach plastic drum pontoons to the sides to increase buoyancy and balance.Design Statement
A stuffing box, or packing gland, is used around a propeller shaft at the point it exits a boat's hull underwater. It is the most common method for preventing water from entering the hull while still allowing the propeller shaft to turn.
In a conventional stuffing box, the seal itself is provided by packing rings, or a square cross-sectioned rope, made of greased flax, which is packed or wound tightly around the propeller shaft, and compressed in place with a threaded nut and spacer. The box may also be fitted with an opening for periodic insertion of grease between the rings, and sometimes with a small grease reservoir.
Our design requires 5 stuffing boxes, one for the propeller drive shaft, and 4 for the axels. We will be constructing our own stuffing boxes.
