      It’s Memorial Day weekend and I’m stuck at work. To make things worse business is slow. Everyone is in the pool or at the beach. So with plenty of time on my hands I’ve been looking at Pete’s DC generator/dive compressor and can’t help thinking that it is a fantastic idea. Even without the compressor it seems that a simple DC generator with a small diesel would not be too difficult to put together. I have not been able to find a genset for less than 10K that looks suitable for installing on the boat. I have thought of using a small Honda EI 2000 on the swim platform for the short term to run my trailer park A/C setup in July and August. 90 degree temps with 99% humidity makes it tough to sleep. I got the Victron inverter that has power assist to meet the start up demand of the A/C compressor by switching to inverter when the demand exceeds the output of the generator, thereby letting me get by with a smaller generator. What type of generators do some of you have and what would you change about your setup if you could? I know it will be a while before I get any responses because everyone else is out sailing while I sit here almost alone. At least I got all the wings and beer you could ask for and the scenery is not far from what you have at the beach.

      Hey Linus,

      I’m celebrating Memorial Day with some fiberglass work on my foredeck/chain locker project. I’m on the home stretch with that now, about to deck it over, mount the new windlass and move on to something else. Actually, what I’m doing right now is procrastinating (I do so love messing with fiberglass!) by answering your email.

      On my last cruising boat I had a 4 HP, one cylinder Yanmar diesel engine mounted at the after end of an over-long quarter berth compartment. All it did (in my case) was drive a huge alternator for fast-charging the batteries using minimal fuel. A big inverter provided all the AC I wanted, sans air conditioning. As I recall the Yanmar only burned a cup or two of fuel per hour. There were wheels (sheaves, pulleys, sprockets – whatever you call them) to accommodate a couple of more attachments, so it could easily have driven a compressor. This engine was air cooled when I got it and sounded like a fleet of helicopters in the harbor. I fabricated a water-cooled, muffled exhaust system for it, though, and it became tolerable to operate.

      My inclination this time around is to go with the Honda 2000 for extra juice when I need it, just because it’s simpler and cheaper.

      Now, how about passing me some of your wings & beer.

      Linus, if it is any consolation, we are working in Canada today as well. My
      boat came with a 4 Kw Apollo genset. Because of this, the refrigeration
      system is a Seafrost 110V (BF-3) system, so I am stuck having to run it
      daily. It also has a 12,000 BTU Cruiseair system, so in theory, I could air
      condition while sailing. It was a live – aboard Florida boat, so I guess
      that explains the setup.

      If I were starting from scratch, I assume I would have gone the solar / 12v
      route for less dollars. However, that would not address your need for
      air-conditioning in the summer. I probably also would have purchased a Honda
      EU 2000. It sounds like most people are pretty happy with them and they only
      cost around $1000. At a 5 year life, that is $200/yr, less than the interest
      cost on a full diesel genset. If you are wanting to air condition all night,
      they would be the quietest way to go. Note, you can get adapters to run them
      from a larger, portable tank, like you would use for an outboard. Of course,
      the biggest hassle over a diesel genset could be the handling of the gas,
      depending on your circumstances.

      Going the homemade route could be pretty cost effective. Rich Boren (Pearson
      365) also went that way, adding on a water maker at the same time. I think
      Alan is also making one. Rich picked up his Kubota diesel for $500 off of
      e-bay. Here is a link to a discussion on his system

      Hi Linus,

      I bought Pelican in June of 07 and was living aboard at a mooring in City Island, NY. I got the Honda 2000 EU for around 850 with shipping on line. I have used it to heat my water, charge batteries, and do all sorts of stuff – I may even get a 120v hooka for underwater maintenance.

      As far as work goes, I had to rebuild my head yesterday with company aboard.

      I have seen enclosures for the Honda to be mounted on trucks and trailers that don’t seem to have much in the way of louvers or openings for air. Being air cooled I had been afraid to put the generator a box but after looking at those I was thinking of using a cheap Igloo cooler that I could drop the generator in and have a deck plate at each end to allow air in and also cut down on noise while protecting the Honda from spray while on the swim platform, It would also be a storage box with the deck plates in place so I can keep the gas fumes with the generator. Thanks for the input I think that I will give the Honda a try. Besides you can use it anywhere, just have to remember to bring it to the boat when you need it.

      For several years, I had a 2200W Yamaha generator mounted on the forward companionway sliding hatch cover. I made a canvas cover for it to keep sea spray and rain off it. It worked fine, but made too much noise. The unit I owned was fairly quiet, but in a quiet anchorage, this was even too noisy. I understand that these things are quieter than they used to be. If you don’t mind replacing it every few years, they would probably work well.

      There were a couple of problems with the installation.
      Placing the unit forward of the hatch also placed it forward of the head dorade vent.
      Caution was needed to make sure that the cabin was properly ventilated.
      The fuel tank was not removable. This made it awkward to refill. I had to lug a jerry-can around.

      I case you don’t follow the SSCA DB, here is an on going discussion on Gas
      vs Diesel gensets that may be of interest. As allows, it covers opinions on
      both sides of the issue.
