Which Watermaker Is Right for Your Boat?

Boat type → power supply → crew → model recommendation

Choosing a watermaker is not as simple as matching boat length to litres per hour. Your power system (12V batteries only, or 230V generator?), daily water consumption and cruising style — anchorages vs marina nights — all shape the right choice. This guide walks you through the Seacraft SCW range step by step.

For a deeper look at daily consumption and hourly output, read How to Choose a Watermaker for Your Yacht.

4-Step Selection
  1. Boat type and size
  2. Power supply (12V / 230V / 380V)
  3. Daily water requirement
  4. Model match

Step 1 — Identify Your Boat Type

Segment Typical Length Recommended Models Not Recommended
Small sailing yacht / tender 8–15 m SCW-30, SCW-50 SCW-500, SCW-1000
Mid-size sailing yacht / catamaran 15–20 m SCW-50, SCW-100 SCW-500, SCW-1000
Motor yacht / gulet 18–25 m SCW-100, SCW-150, SCW-350 SCW-30, SCW-50
Large motor yacht / superyacht 25 m+ SCW-350, SCW-500 SCW-30, SCW-50, SCW-100
Commercial fishing vessel 25 m+ SCW-500, SCW-1000 SCW-30 – SCW-100

Step 2 — Check Your Power Supply

12V DC

SCW-30 & SCW-50

For sailing yachts with battery banks only — no generator required. Can be supported by solar panels. Output: 30–60 L/hour.

230V / 50Hz

SCW-100 – SCW-350

For motor yachts, gulets and large sailing yachts with generator or marina shore power. Higher output, shorter run times. 100–350 L/hour.

380V / 50Hz

SCW-500 & SCW-1000

Commercial vessels and shore-side installations. High power requirement. Output: 500–1000 L/hour.

Practical rule: If your boat runs on 12V batteries only, SCW-100 and above are not practical — running them through an inverter drains batteries quickly. Stick with SCW-30 or SCW-50 on pure 12V systems.

Step 3 — Estimate Daily Water Consumption

Average consumption per person per day on a cruising yacht:

Use Litres / person / day
Drinking water3–5 L
Cooking, tea, coffee5–10 L
Shower (short)20–40 L
General cleaning10–20 L

Example: A 6-person sailing crew with moderate shower use needs roughly 150–200 L per day. An SCW-50 (50 L/hour) running 3–4 hours covers that. A 12-person gulet on a blue cruise can easily need 400–600 L daily — SCW-150 or SCW-350 is the better fit.

Frequently Asked Questions

No. Two boats of the same length can have very different crew sizes, generator capacity and cruising habits. Length is a starting point — power supply and daily consumption determine the final recommendation.

SCW-50 is the maximum 12V output in the Seacraft range. You can run it longer each day, add solar to support battery charging, or upgrade to a 230V SCW-100 if you install a generator or inverter system. Our team can assess your battery bank and advise the safest path.

Yes. We install directly at your berth in Göcek, Marmaris, Bodrum, Antalya and marinas across the Turkish coast. Book a vessel survey before installation — most surveys can be done by video call if you are not yet in Turkey.

We strongly recommend it. Our technicians assess your boat's power, space and plumbing before confirming the model. Use the appointment form to book a survey.
