I will be taking delivery
This Sept. 24 in La Rochelle and need to know how far she'll go on 53 gallons of diesel
First of all, if you still have the chance, go for the 30 HP instead of standard 20 HP's.
I own Orana
with 2X40HP Volvo
sail drives, standard props. Never used 2 engines at the same time, unless I am heading to very strong winds, high waves or strong current
. One engine
at 2100-2200 RPM
easily gives me 6+ knots.
web side gives a conpsumption of 0,5 gallon per hour at 2.300 RPM
for yr engine
. (assuming that is a new generation D1-20 serie engine). That should give you 6 knots w/out problem. (If not then in my view 20 HP's are too small for the boat)
If you get 6 knots with this consumption
, you should get a range of app. 600 nm.)
Remember, this is for perfectly calm water
, no wind
. If you can sail motor
the range would get longer. Ia you head
heavy seas/winds, that's another story; two engines at around 2.000 RPM would be necessary. Then total consumption of 0,8-0,9 gal per hour is likely and you should average beetween 5 and 5,5 knots.
