Planning Water Tank Capacity With Your Watermaker
Tank volume plus production = anchoring freedom
Formula
Reserve = Tank volume + (Hourly output × Run hours). Two days at anchor needing 300 L with a 200 L tank leaves a gap — daily 150 L production closes it.
Strategy
- Fill overnight on generator, consume by day
- Two hours watermaker each morning at anchor
- Hybrid marina + watermaker (cost comparison)
