Exactly. Use some common sense and courtesy. No one group gets to have all their way all the time. The world is only getting smaller.

I'm a sailboat owner with no genset who is on the brink of becoming a trawler owner with two gensets. So I'm reading this with great interest!

I must anchor in different spots than some other folks. Rarely am I near anyone at all, much less often close enough that I could even tell if their gennie was running or not.

Sometimes raft up for a gathering, but that is noisy mess of fun on purpose.

Never been offended by another boat running a gennie.

The Eagle has a main 10 kw gen and a 5 kw cruise gen which are more popular on single engine and sail boats. The main gen is run the mian 671 is not running, and it power the hydraulic for the get home and bow thruster. The crruise gen is run when the 671 is running, so we always have 120 volts AC, dock, criuse or main. The main 10 kw gen has 2700 hours, but the 671 has 1, 500 hours.

We also have an inverter and three 8 D batteries, which we have used occasionally. In the PNW solar is very limited with little sun and wind is not consistent. The primary purpose use of the mailn is to power the hydraulics, and AC secondary as we do not anchor so we have dock or use the cruise most of the time

This June were are going to see if we're can bet more get more thurst from the bow thruster, increase gen set rpm, increase sizes of hoses and or pulley and belts. The main gen set is the limiting factor,

So to get back on point. If you have an anti-generator bias, why? If the boat is equipped with a genny, why not use it? Most gennies I have seen are mostly quiet. Yep there are a few that are noisy but not many. So why spend all the extra money, time and space for solar/wind?

See, thats the difference...

We also have a properly installed NL generator. You cannot hear my generator at all for example walking down the dock. As you walk down the finger you can start to detect something, and if you stand on the swim step you can kinda hear it.

Compare that to my slip mates diesel furnace which sounds like a jet turbine running next door.

Yes, and I need to correct, the brand of generator isn't relevant, the sound produced when its running is.

There are in my opinion only two reasons not to have a generator

1. Your boat is not designed to have one
2. you do not want to spend the money on one.

We can always find a way not to "need" something so "don't need it" doesn't count. Generators add flexibility.

Maybe with an older mechanical diesel. I would never consider putting used motor oil in the tank with a modern common rail diesel. I would not want to subject that 2 micron fuel filter to extra crap from dirty oil.

In boats with low electrical consumption (gas cooking, no A/C, LEDs, ...) solar/wind can greatly reduce the time the genny is run and still keep the batteries fully charged. This is good for the batteries as they are fully charged and not cycled as low. It is also good for the genny as it it not run under-loaded for a long time to fully charge the batteries.

If the genny needs to run for several hours a day anyway, for A/C or electric cooking, then I would think solar/wind probably do not make sense. There are many other opportunities to "invest" in a boat!

My boat is equipped with a very nice inverter, 8kw genset, and after the refit a very nice battery bank. Everything can run very nicely overnight off the battery bank with the exception of the electric stove and the ac/heat. I view generator usage in the same way as the engine. Plan to use it whenever I need it, but won't run it if it's not needed. See the boat similar to my home. Plan to be comfortable; no nautical camping here. That being said, I don't leave every light on in the house 24/7 to save the effort of throwing a switch when entering a room. So to with the genset, only when needed, but always whenever needed.

I was at Baranof Warm Springs a few years ago between seine openings. The dock was filled mostly with seiners, except for 3 or 4 pleasure boats and a big packer. The packer had to run its generator the whole night to keep fish cold.

Since they had plenty of extra power, they provided shore power for anyone on the dock via huge power cords with junction boxes on the end. This at least partially mollified the sailors on the dock.

Yep. That is me also.

It's simply not efficient to run the Gen simply to charge the batteries. It takes forever.

Also when anchored, I like the quiet. If I want noise, the main engine can do that and get me somewhere at the same time.

Value of two solar panels and a small wind generator. Ran generator at six am this morning for 1/2 hr. Since then we have been on the boat with refrigeration going and have done a load of wash in the Splendide and made water for two hours. Current state of charge at 4:30 pm is 12.8.

Admittedly this is unusual in that a trough is coming through Martinique and we have had winds in the 30kts for a couple of days and the sun is shining.

Only downside is our Magnum inverter/charger will not charge at bulk mode unless the voltage is below 12.6 volts - but I can trick it by turning on the tea pot. Thus we can both charge the batteries and turn on the water heater for 15 minutes tonight. (Tea pot is tuned off as soon as Magnum begins charging.)

No problem for me with the 6 am generator running. Boats on all sides are friends and everyone is up with the sun.

Multiple ways to generate amps are good, I see no reason to run the genny if I can get amps passively, like via panels. But for some jobs only the genny will do, and I`m not hesitant to start it. I can make tea with LPG, but can`t run the espresso machine without the genset, which I load and multitask if I can.

To recycle it yourself and reclaim some of the money spent on it. Plus if you're running around in the boonies you don't have to store it till you find a way to properly dispose of it. Some engine manufacturers even state you can mix between 1-10% used oil in the diesel fuel you are feeding the engines.

But I understand why some people are skeptical of this. As they are of extended hour oil changes based on proper oil analysis with perhaps bypass filtration. But I'm sure the petroleum companies love you.

This may be of interest to some:

My two cents worth.

I have a good size genny that came with the boat and I use it for battery recharging, refridgeration and hot water. It is an well installed modern unit with sound shield. When out and about I use for an hour or so in the morning and same late afternoon.

In the more remote bays we access no one, but no one leaves their generators on much after sunset, on boats like my IG 36' with an above waterline through hull fitting generator noise is inevitable.To me part of the problem is the type of noise a generator makes, that low insistent never ending diesel drone with the water whoosh to accompany it.

Sometimes in summer down here the cicadas can be deafening far far louder than generators, however who doesn't like being in the middle of nowhere surrounded by that cacophony of sound, likewise who doesn't feel his/her blood pressure rise with the sound a of a single generator splitting the night in a secluded bay.

A couple of years ago we were in a bay with about five other boats and one had the genny running well into the evening. We were all pretty cranky when a voice from the end of the bay boomed out,"turn the f**cking thing off", a couple of minutes later dead silence. This was followed by clapping from the other boats in the bay.Once everyone had settled down we then all went back to opening another bottle of wine and putting some music on. Yes, I know a bit hypercritical of us it's just the sound of conversation and laughter with a bit of music on is closer to the cicada end of the spectrum than the generator.

For me the ultimate is to run my boat without the aid of a generator, while not breaking the bank to achieve it.

To Run or Not to Run the Generator

However, the last 10-20% of the battery charge takes 1-2 hours *after* bulk charge is complete to top them off properly. Being on a mooring most of the time, I don't have the luxury of shore power to provide the relatively small amount of power required for that final topping off. To help the batteries live longer I am planning on installing a single 100watt solar panel. My total outlay for the solar will be less than $300. I expect it will pay for itself in less than 2 years.

What he said. I'd like solar to top up the last 15-20% charge on the batteries, every so often! to keep them happy. I hope to install a solar charging option in combination with the genny for that purpose.

I'm surprised that no one has commented on the noise made by a sailor's Honda 2K gas generator buzzing away on his foredeck for hours into the night. Frankly, that noise can drive me nuts.
