Marine Watermaker Options:

• Compact reverse osmosis systems for smaller yachts (30-60 gallons per hour) typically cost between $15,000-25,000 for installation and equipment
• Medium-capacity systems (60-120 gallons per hour) suitable for most recreational yachts range from $25,000-45,000 with full installation.
• High-capacity commercial grade systems (120+ gallons per hour) for larger vessels cost $45,000-100,000, offering redundancy and advanced features
• Installation costs typically add 25-35% to the base unit price, including plumbing, electrical work, and control integration

2. Annual Maintenance Budget

Regular Maintenance Expenses:
