Engine RPM vs Boat speed for Amel-Super-Maramu 2000


VLADIMIR SONSEV
 

I bought my boat several months ago. Boat was made in 2002, she has 75 HP Yanmar engine.
I decide to establish my boat performance characteristic. I tested boat speed at three different engine RPM. My test results are as follows:

Engine RPM           Boat speed in KN
1500.                                  4.7
2000.                                  6.3
2500.                                  7.5

Boat speed test minimised current or wind effects. The speed was taking from GPS at maximum stable speed.
I wonder if those results are as good as expected or not. Do we have any similar data from Amel?
