Hull Vane BV estimates it has invested at least
€2 million in Hull Vane-related research.
This year the company will market a semi-
custom Hull Vane for inland and offshore
boaters. It has developed a standardised version
for 10m-20m boats, based on common hull
parameters for that length bracket. The semi-
custom Hull Vane consists of aluminium
extruded profiles, and is adapted by varying the
size and position relative to the transom, while
the profile shapes are always the same.
The ‘dynamic’ version may premier at Monaco.
It rotates around an axis to vary the angle of
attack and is for large yachts and naval ships. This
Dynamic Hull Vane is billed as the world’s first
active pitch stabiliser for displacement ships. “We
will have the only pitch stabiliser on the market,”
says Bouckaert. “We already have a patent.”To develop the dynamic Hull Vane, the
company knocked on Naiad Dynamics’ door.
Bouckaert: “A Dynamic Hull Vane includes
technologies we are unfamiliar with like
mechanical pivot points and electronic and
hydraulic control systems. We know underwater
hardware. Naiad has much experience with
hydraulics and stabiliser controls.”
The Dynamic Hull Vane (shut it off and it
is a fixed wing) also acts as a pitch stabiliser.
That’s novel. Boats have roll and zero-speed roll
stabilisers but no pitch stabilisers. “We intend
to change that, offering owners the ultimate in
comfort and efficiency,” says Bouckaert.
He says in principle just about all steel and
aluminium yachts are Hull Vane candidates.
That only about 5% of the world’s 80,000
commercial ships qualify does not faze him.
Tankers and bulk carriers are never in a hurry.
“And 5% of 80,000 vessels is still 4,000 vessels,
on which we can achieve extraordinary efficiency
gains” he says.BRUNO BOUCKAERT | SALES MANAGER
