To be completely off oil
is unrealistic, unless you have all the time in the world.
Our preliminary test results show that sailing and limited motoring can be done with out the help of fossil fuel
. However on longer voyages with the possible no wind
conditions along the trip a emergency generator
can be useful. Depending on how much solar
power is installed, in case of our testing FastCat
1800 watt Peak the use of this emergency generator
can be minimal.
In the next 2/3 months we will find out if this generator is really needed while sailing
Green eMotion to Europe
from Durban via Cape Town
, Cape Verdi Islands a trip of 10.000 NM. we will keep an exact log and the diesel fuel
on board will be measured both in the beginning and the finish of this trip.
If we find out that none or almost no diesel fuel is used ( cooking
is also done electric )
we can save another 500 kilo or 1100 lbs by not putting a gen set in and leaving the fuel out.
I expect the generator will only be used during the passage
thru the doldrums if at all.
