Questions => Decisions
ask the right questions, create an open set
2.1 Hull shape
all agreed a sheet based keel is good for testing different shapes.
evaluate options for a rugged hull:
air-pressurised vers. foam filled segments vers. conventional solid, sheet based.
all agreed on streamlining the segmented hull => flexible membrane vers. overlapping petals.
petals are more robust but complex -> need a lot of different shapes ; mechanical fragile, may get jammed.
2.4 Motor/Control/electronic components
option A is favourite
2.5 Transmission of power
2.5 Emergency procedures for the sail
