We've got a little Paguro genset in the cockpit
locker with an exhaust on the inner starboard hull
It's not any noisier than most boat gensets and probably quieter than a petrol Honda
on the back steps. Still, any engine
running at a quiet anchorage is not a good thing. There is always a sigh of relief on board when I shut the generator down. Diesel
fumes in the cockpit are not a problem. We try not to use it much, but it gets turned on when we need to make water
or the sun fails to shine on our solar panels
. We try to make water when traveling, this provides cleaner water to our water maker filters and means that generator noise
I'd not such a problem.
The noise level is higher behind or in front of the boat than in the cockpit. The sound is directed out either end of the between hulls tunnel. This can be a very useful feature to repel those who like to anchor
too close to me!
We have a normal wet exhaust which exits 150 mm above waterline. I think ours would be quieter if the rubber flap on the exhaust end cap was removed, or better still, an exhaust water separator was fitted.
By the way, are you committed to a Fischer-Panda? We heard lots of bad reports from owners when we were researching gensets. I can't give a glowing endorsement of Paguro generators either, as ours is only 18 months old but has not performed as well as expected.
