Do I need a real sextant?

No. Sailcasted simulates the sights — you receive the altitudes already measured with realistic noise injected. You need your HO 249 tables, a nautical almanac, a plotting sheet, a ruler and a compass. The goal is to practice sight reduction and line of position plotting.
