QUICK ANSWER÷
Required output starts with litres per day—not yacht length.
Add realistic freshwater uses, divide the total by the planned daily operating hours, then review reserve, storage, seawater conditions and available power. Yacht length helps describe the installation, but it does not replace a demand calculation.

MARINE PLATFORM SELECTIONTWO SEAWATER PATHWAYS
Compact DC watermaker or higher-capacity PM platform?
DESAL YACHT30 · 60 · 110 L/h
For compact onboard production where 12/24 V integration, footprint and normal yacht service access lead the decision.
- PRO and PRO Touch configurations
- Six catalog codes: STD-0001–STD-0006
- Compact yacht and sailboat route
DESAL-SWRO PM62.5–1,041.67 L/h
For larger yachts and vessels where required output, longer duty and an engineered electrical arrangement move beyond the compact platform.
- 11 A, B and E catalog configurations
- Marine seawater duty up to 56,000 µS/cm*
- Project-specific power and integration review
*Catalog duty boundary; final output and configuration depend on verified feed water, temperature, pressure, intake condition and the approved technical proposal.

ONBOARD INSTALLATION REVIEW
The watermaker needs an operating envelope—not just a free corner.
Six interfaces determine whether the selected platform will be serviceable, quiet and dependable onboard.
Intake & discharge
Locate the seawater intake for stable submergence and clean flow; coordinate an unrestricted, visible brine discharge.
Pretreatment access
Allow service clearance for strainers and cartridge filters. Intake quality and harbour operation determine the final arrangement.
Power & protection
Verify voltage, cable run, protection, battery or generator duty and realistic concurrent onboard electrical loads.
Service envelope
Reserve access for filters, pump, membrane pressure vessels, preservation and normal inspection—not only the equipment footprint.
Noise & vibration
Use a suitable foundation, flexible interfaces and separation from accommodation spaces where practical.
Marine materials
Seawater-wetted components, fasteners, piping and installation practices must suit the vessel and marine environment.

MARINE APPLICATION FAQ
Questions that change the selection.
01How many litres per day should I allow per person onboard?
Use the vessel's real consumption records whenever available. Showers, cooking, drinking, deck wash, laundry and guest expectations vary widely, so a generic per-person number can mis-size the system. Add each use, define storage and then apply a design reserve.
02Is the smallest calculated capacity always the best choice?
No. The calculation gives a minimum nominal output. Colder or more saline water, membrane condition, available power, desired runtime and reserve can justify the next capacity. Final selection follows the vessel review.
03When should I move from DESAL YACHT to DESAL-SWRO PM?
DESAL YACHT is the compact 12/24 V route at 30, 60 and 110 L/h. DESAL-SWRO PM extends marine seawater production from 62.5 to 1,041.67 L/h for larger demand and engineered power arrangements. Overlap is resolved by installation, duty cycle and electrical constraints.
04Can a watermaker operate while the yacht is in a marina?
The equipment can only be considered after reviewing local water quality and intake risk. Harbour water can carry suspended solids, oil, biological loading and other contamination that may require different pretreatment or make operation inadvisable.
05Are the stated flow rates guaranteed in all sea conditions?
No. Catalog capacities are selection references. Actual output depends on seawater temperature, conductivity, pressure, membrane condition, intake conditions and installation. Guaranteed performance is defined in the approved technical proposal.
