Design Requirements

• Limits heeling to 20-30 degrees with winds at 30km/h
• Waterline should be in a certain spot (needs to be determined)
• Low hydrodynamic drag on fore/aft axis
• High hyrodynamic drag on port/starboard axis
• Hull attachment points are waterproof
• Keel can be detached and reattached to the hull

Constraints

• Uses existing 1/4” threaded rods with existing spacing to attach to hull

Considerations

• Math to figure out how heavy and how far down the keel needs to be

• Lead is ideal material, but molten lead is difficult to work with
• One solution is using small lead scrap (will need to find/buy somewhere) and an epoxy mold - https://www.youtube.com/watch?v=reXc0vZ47N4
• Ideal hydrodynamic shape looks something like a teardrop for the bulb, maybe it is a good idea to put an acrylic plate between the threaded rods to increase drag side-to-side (do we need to worry about an airfoil shape here as well?)
• Need a good order of operations for manufacturing
• Attachment points to hull currently (using 1/4” nuts on either side of the aluminum extrusion substructure) not waterproof (water can leak in where the threaded rod exits the hull, need to figure out how to seal while still allowing keel to be removed. Or maybe we just attach the keel permanently?

Figure out assembly all masses and COM
