Once I close the storm boards and zip down the cockpit awning I can't hear the genset i wonder having the 2 would make it louder or just hum at the same decibels? I sleep in the bow can hardly here it.


What about your neighbours??

I splashed out and bought a fridge and a 2000w inverter at xmas plus 2 new batteries. I have installed the batteries but not the inverter and the fridge has hardly been used. Reckon I have gone that long with the luxuries that I'm no longer bothered by their absence.

I have moved the small computer fan over my bunk!

What I meant for air circulation on still nights was the "air conditioning" systems used in Arab cities where they use vertical towers to create drafts. It would mean some research on designs and then stitching up a unit in sail cloth. Unit like this attached to a deck hatch and hauled vertical might be the answer.


I thinking you're referring to "wind catchers" (en.wikipedia.org/wiki/Windcatcher). They are a form of evaporative cooling, and would probably work great in southern Australia, i.e., dry, hot summers, esp. SA. Not likely to be effective in the tropics though.

Yep that's the idea. If it works in Barbados it would suit the Whitsundays.

For deck shade something along this style appeals.

Two hours per day running my genny is well worth my 38L Engel and my 8 hours a day of 13 or so 'free to air' tv channels @ 60 watts/hour.
ACE, I'm assuming that you are trying to boot the a/c compressor with the Hondas governor turned off. That is, when the a/c switches itself on the generator was already running flat out (a full 1600 watts) eco-throttle turned off.
Something to think about.....whenever I use the windlass, IF my gen is in eco mode, and just ticking over running the freezer for example, withinin a few seconds of pulling 900 watts with the windlass the genny trips...because the instantaneous load req'd by the windlass, say a momentary surge of much more than the rated 900, actually is greater than the 1600 available. So to use the windlass, genny running flat out @1600w. When anchor is docked only then can I actuate the eco throttle and the gen settles down to its' desired speed.
IS IT POSSIBLE, that your Honda WILL in fact boot your a/c if running flat out prior to the a/c booting? Maybe just honda one will do the booting job.
Is it possible that even with 2 Hondas delivering 3,200 watts, they need to be running flat out because the induction load of the compressor is greater than the juice available WHEN @idle speed.
If you already know all this then sorry for the ramble.
Been on the hook for six years running gennies and have made every mistake in the book, mechanic or not.
If you want to talk pm me and I'll give you my mob #
Cheers.


Why did I bother.
