T&T: Active Fin Stabilizers

[Joel Wilkins]

Don't know if they would make the data available, but when the Nordhavn 40 went from CA to Hawaii I seem to recall that they shut off the active stabilizers to conserve fuel. Perhaps a call to Jim Lishman or Nordhavn would get long term data you need.

  Does anyone have any before and after data on what speed and fuel
consumption they got a given RPM prior to installing Active Fins VS after
installation what speed and fuel consumption they got at the same RPM? There
is a price to pay in economy as you are creating drag, I would like to know
how much that price is before I make a decision on installing them.

For those slower trawler folks that have them........Are they still
effective when you are only making 6 knots speed through the water? I am
not talking about 6 knots speed over ground. The Stabilizer only knows the
speed at which they pass through the water. The lift is a function of the
speed squared and if the speed is too low to create the needed lift then you
put larger fins on. This creates more drag and less economy.
