Water Needs for Gulets and Blue Cruise
Crew plus guest consumption, watermaker capacity and model direction
Water demand on gulets and blue cruise boats is higher than on a typical sailboat: crew and guests sail together, shower use is heavy and routes rely on anchoring in bays. Watermaker selection depends on head count and usage habits, not boat length alone.
Our product selection guide recommends SCW-100, SCW-150 and SCW-350 for motor yacht / gulet (18–25 m); SCW-30 and SCW-50 are not recommended. Use our capacity guide for daily litres and tank + watermaker planning for storage.
Gulet Difference
- Guests + crew together
- Heavy shower use
- Bay cruising — limited marina water
- 230V generator — outside 12V segment
How to Calculate Daily Consumption
Same averages as our capacity guide. Gulet and charter routes usually use medium–high columns.
| Item | Low | Medium | High | Unit |
|---|---|---|---|---|
| Drinking water | 3 | 4 | 5 | L / person / day |
| Galley, drinks | 5 | 8 | 12 | L / person / day |
| Shower | 15 | 30 | 50 | L / person / day |
| Cleaning, laundry | 5 | 10 | 20 | L / person / day |
Formula: Head count × litres/person/day = daily total
Our selection guide notes a 12-person gulet may need 400–600 L/day. The capacity guide's 12 crew / 24 m gulet example uses high consumption at ~600 L/day and points toward SCW-350.
Example Gulet Scenarios
Aligned with our capacity guide and location pages.
8 people — mid-size gulet (~20 m)
4 crew + 4 guests, medium-high use ~45 L/person/day
Daily total: ~360 L (capacity guide — 8 crew motor yacht example)
Model direction: SCW-150 (150 L/hour) → ~2.5 h/day. Requires 230V generator.
12 people — blue cruise gulet (24 m)
Crew + guests, high use ~50 L/person/day
Daily total: ~600 L (capacity guide)
Model direction: SCW-350 (350 L/hour) → ~2 h/day.
20–24 m blue cruise gulet (Göcek profile)
Our Göcek location page cites SCW-150 Pro Modular and 2–3 hours/day for typical 20–24 m blue cruise gulets (8–12 people band).
Note: Final model at survey with head count and tank volume.
24 m+ or 12+ people
Göcek FAQ and SCW-350 product page: step up to SCW-350 above 24 m or more than 12 people.
Target vessel (SCW-350): 20–30 m motor yacht, gulet, large sailboat — 350 L/hour, 230V.
Seacraft Model Direction for Gulets
Target vessel and capacity from product pages — starting point only; survey required.
| Model | L/hour | Power | Target vessel (product page) | Run time at 600 L/day |
|---|---|---|---|---|
| SCW-100 | 100 | 230V | 12–18 m motor yacht, mid-size sailboat | ~6 h* |
| SCW-150 | 150 | 230V | 14–20 m motor yacht, large sailboat, gulet | ~4 h |
| SCW-350 | 350 | 230V | 20–30 m motor yacht, gulet, large sailboat | ~2 h |
* Capacity guide targets 2–5 hours/day; above 6 hours suggests a larger model. SCW-100 may suit lighter gulet profiles; heavy blue cruise load more often points to SCW-150 or SCW-350.
Power and Tank Planning on Gulets
230V generator
SCW-100 – SCW-350 on gulets are 230V / 50Hz AC. Units usually run while the generator is on. 12V vs 230V — gulets sit in the 230V segment; SCW-30/50 are not suitable.
Fresh water tank
Gulets may have large tanks; blue cruise still drains them in days. Tank = buffer; watermaker = sustainable production — tank + watermaker planning.
Charter gulet
Capacity guide: size for peak guest load, not average day-use alone. Final model confirmed at survey with tank volume and generator hours.
Blue cruise route
Capacity guide: water independence matters more on blue cruise from Göcek, Marmaris or Bodrum than on marina-hopping itineraries. See service locations for installation areas.
4 Steps to Plan Gulet Water
Total head count (crew + guests)
Litres/person/day — medium–high for blue cruise
Daily total ÷ L/hour = hours/day (target 2–5 h)
Survey — generator, tank, installation space
