I’m curious if anyone has a watermaker in their Nic 38? We’re thinking of getting a modular DC version (either Echotec or Village Marine) and pondering the best place to install it. Anyone have any words of advice about installation locations? Thanks – |

Hi Jeff – thanks for the reply. Yes – watermaker decisions are tough. They are not cheap and add maintenance. Do we really need one for our future cruising plans? If yes, what’s the best watermaker? I’ve been pondering this for a couple months, reading as much as I can. We finally decided that there is no right answer, so we decided that if we get one, what is best for us is: 1) If we buy a DC model, then we can run from renewable energy when possible, and run the engine to produce DC power when desperate. Besides, an engine driven one makes me think we’d be lugging from shore jerry cans of diesel rather than jugs of water. 2) We won’t use excessive amounts of water just because we can make fresh water since running the watermaker is not free. 3) We have to run the watermaker frequently to avoid pickling, so we’ll pick a unit that in about 3 hours run time will produce our needs and run it every 2-3 days using excess renewable energy. 4) We’ll pick a DC unit that has consumables and other parts readily available from a variety of sources, rather than pick one that requires proprietary (and therefore more expensive) parts. Hope these guesses are right for us. It’s so hard to know, without ever having used one. But I think we’re about to buy one and find out. Marilyn |

Hi Jeff – We’ve learned that the 2 of us comfortably need about 4-5 gallons. Sure we could use more, but that’s enough for our normal cruising lifestyle. So if we run the unit every 3 days for 3 hours, we’ll need to produce 15 gallons usable water plus the water needed for flushing the system (maybe another 3 gallons). If we decide we need more water than that, then maybe we’ll run the unit every 2 days so we can have 7.5 gallons per day. Our future cruising plans take us to where reliable water will not be available, so we’re going to have to do something. We’re debating on adding wing tanks to increase capacity and then rely on rainwater catchment, or install the watermaker and believe that a mechanical device will work when we need it to. Both solutions have a certain amount of faith involved. We will update later if we decide to buy one and install it. Marilyn |

When we took up cruising I removed the heads in the aft cabin and put in easily dismantled shelves throughout and I fitted a box construction across the the locker where the WC had been but only about ten inches wide in the fore and aft direction. Essentially just big enough to hold the water maker. The construction of the box allows it to be completely dismantled for servicing the watermaker. My “error” was to fit too small a watermaker: Katadyn power survivor 40E. This only takes 4 amps and we had the capacity to generate a spare 4 amps when it was fitted. It on,y produces 5.5 litres per hour. This was sufficient for three men sailing from Europe to Brazil with daily showers, etc. but we did run it for ten hours a day. With hindsight I should have got one that consumed 8 amps. I would have got very much more water per amp hour. |

Hi Marilyn I use 12v village Marine. It produces 12 Gph, using very little amperage. I mounted the unit, supply pump and 2 filters under port v berth. Added a couple of access hatches. I run it when the aux is running. 25 gal day tank is at the bottom of the standing locker. |

We decide to install a Village Marine Little Wonder LWM-145 in the aft head space (which is no longer a head on our boat). The unit seems to work as spec’d. I think the manual is HORRIBLE. It’s a mishmash of former information from before Parker bought the company, and new Parker information. Sometimes the information is contradictory. We bought the unit from Oil Filter Service in San Diego. Funny name for a company that sells watermakers, but they are a large Parker distributor and so picked up these LWM models. I found Oil Filter Service to be very helpful, and I would buy from them again. They have an online shop where you can see prices. We got a good sale price during the San Diego boat show, and then had the unit shipped to Seattle for us to install it. Their technician gave us phone support during the install. |

Just wanted to see if anyone had updates to offer this thread? I am thinking to install a water maker for Pacific cruising and general live aboard ease. I have narrowed it down to Katadyn PowerSurvivor 40E but which seems to be a bit on the low capacity side, and the Schenker Zen30 which is latest technology, 30 litres/ hour and more expensive, around £4000 all bits included… Has anyone found a good spot to install one other than in the converted aft heads? I do not have an aft head on my boat. But that cabin is mainly storage so in terms of noise it perhaps makes sense to have it there. However it’s a long way from my toilet /galley sink seawater inlet, but not so far from the engine raw water inlet. Any thoughts? |
