← HistoryWhich capability allows the mariner's astrolabe to achieve accurate readings at sea?
A)Weighted alidade resists wind effects✓
B)Complex gear trains track sidereal time
C)Simplified scales aid rapid calculation
D)Hermetic sealing prevents corrosion damage
💡 Explanation
The mariner's astrolabe uses weighted alidade design principles offering an stable instrument base despite the ships movement; the extra weight dampens erratic environmental forces, therefore improving reading accuracy rather than providing computational scale or corrosion control.
