My thanks to you and your staff for the work you
put in on the propeller modifications for “Swordfish
II". It was great to meet some people who
were actually interested in listening to and understanding
my requirements and the disappointment we had in
the performance of what were virtually new props.
Whilst they ran quite well, we were sure that they
could provide better performance, particularly
as we’d spent so much time researching the
options prior to having them manufactured.
I was very impressed with the Prop Scan technology
and the accuracy with which it evaluated all facets
of the propellers. It clearly allows you to determine
the best modifications quickly and confidently.
The proof of that has been demonstrated in the
significantly better performance of “Swordfish
II", especially at cruise speed and above.
We have picked up over two knots at cruise, giving
our most economical running at a little over twenty
knots, which is what we were looking for. In addition,
fuel consumption has dropped by almost eight percent
at this speed, meaning that not only do we get
there faster, we also do it cheaper.
Whilst the props were always smooth running, we
find that the hull pops onto the plane much more
easily. There seems to be virtually no transition
phase in doing so and we are also able to hold
planing attitude down to around thirteen knots.
Top speed is back to what it should be at about
twenty seven knots and the boat really sits beautifully
at all planing speeds.
Thanks again Colin, you and your staff certainly
have my endorsement for your technology and skills.
