This case teaches structured profitability analysis through a less familiar industry, requiring the candidate to think analogously (marina as hotel). The math is straightforward but the key value lies in building a comprehensive framework covering revenue drivers (slips, moorings, occupancy rates, pricing), cost structures (setup, maintenance, wages), and strategic considerations (market size, seasonality, competitive risks, regulatory factors). The thin 3-year profit margin ($134,000 on $4.6M revenue) reveals that success heavily depends on accurate demand forecasting and execution risk—critical for an inexperienced operator.
