Is a watermaker worth it?
A watermaker costs in the neighborhood of $5 grand, plus installation (or DIY) and then ongoing prefilter costs, pump maintenance and membranes. So it really comes down to convenience. If you spend most of your time away from a dock, it’s a great convenience.
How do watermakers on boats work?
How a watermaker works. Watermakers turn salt water into drinking water using reverse osmosis. They pump seawater through a rolled-up semi-permeable membrane at high pressure to filter out the salt molecules and produce fresh water. The pressure required is achieved using a belt off the engine or AC or DC power.
How much does a Marine watermaker cost?
An “off-the-shelf” watermaker can cost U.S.$8,000 or more depending on the capacity and features.
Can you drink water from a watermaker?
Whether you use it to drink, cook, shower or wash, Parker watermaker systems offer more than enough potable water for any size crew.
How do sailboats get fresh water?
A watermaker is a device used to obtain potable water by reverse osmosis of seawater. In boating and yachting circles, desalinators are often referred to as “watermakers”. The devices can be expensive to acquire and maintain, but are quite valuable because they reduce the need for large water tanks for a long passage.
What size watermaker do I need?
The simple answer is “bigger than you think”. General recommendation: 5-20 gallons per day per person. In reality, it depends on how many people are going to be on the boat, where you plan to go and for how long, and what the weather’s going to be like.
Do watermakers work in fresh water?
Yes they’ll work. You’ll get better output from them than you would in seawater too. The way they work is essentially like a really fine filter.
Where do super yachts get fresh water?
desalination
superyachts need to be able to produce their own fresh water through desalination. Having a yacht watermaker (also known as reverse osmosis desalination systems) on board is a huge advantage because of the reduced need to have large, heavy water tanks on board for long charters.
Can you drink rain water at sea?
Normally, a small amount of seawater mixed with rain will hardly be noticeable and will not cause any physical reaction. In rough seas you cannot get uncontaminated fresh water. When it rains, drink as much as you can hold.

How does a Spectra water maker work?
Energy Recovery Watermakers All Spectra Watermakers use a similar energy recovery technology; the high pressure waste stream from the membranes is channeled to the underside of the pump piston, allowing them to recover 90% of the available energy or more.
