through reliable performance and smooth operation. VEEM products are
made at one site under a stringent quality control system.
Propellers for this market require customised designs to ensure maximum
performance. Base propeller designs suitable to conventional ferry
applications include the VEEMStar and VEEMStar-C. These designs operate
successfully on ferries constructed by prominent builders around the
world. VEEM also offer complete propulsion systems for surface drive and
water jet applications. They have extensive experience in the design and
manufacture of innovative and unconventional propulsion solutions.
VEEM uses cutting edge technology in the design and selection of
propellers. This includes noise and vibration prediction, propulsive
efficiency optimisation using Computational Fluid Dynamics (C.F.D.)
software and cavitation tunnel testing, followed by blade strength
calculation using Finite Element Analysis (F.E.A.) software. A cost effective
package is developed using these technologies, applying their experience,
and streamlining the design process.

Super yacht manufacturers seek propulsion systems that provide
maximum propulsive efficiency combined with the smoothest possible
operation. Application specific versions of the VEEMStar or VEEMStar-
LC are recommended for super yachts. The VEEMStar-LC is suited to
applications with high horsepower and limited diameter.
VEEM’s custom engineering of each propeller design is tailored to meet the
specific requirements of each vessel. Problems associated with cavitation,
noise and vibration are solved through optimisation of blade profiles,
skew and sizing expertise. VEEM employs professional engineers and Naval
Architects to ensure that the right propeller is fitted first time, eliminating
the need for costly post trial modifications.

with a complete VEEM shaft line package, designed and manufactured by
VEEM, tailored to suit each vessel.

SUPER YACHTS
VEEM has extensive experience in the super yacht market.
This experience shines through in the success of the designs
for this sector. VEEM’s ability to provide products specifically
for the application means that the performance is optimized,
and tailored to clients needs.

COMMERCIAL FISHING & WORK BOATS
VEEM’s experience within the fisheries market extends for
more than 45 years. Our practical knowledge combined
with the latest technology in software, manufacturing and
design, position VEEM as the market leader. A wide range of
trawlers, fishing boats, tugs and other work vessels benefit
from VEEM propellers.
Trawlers and work boats require a propeller that offers
maximum thrust, smoothness and manoeuvrability, whilst
offering maximum fuel economy. VEEM’s primary focus is
to design propellers with high efficiency. High propeller
efficiency translates to improved fuel economy and
increased vessel speed. For many vessels, the saving in fuel
consumption over one to two years will pay for the cost of
a new propeller.
COMMERCIAL FISHING & WORK BOATS
VEEM offer many designs suitable to the fishing and work boat industry
which ensures that the optimal solution for each vessel is available. For
trawlers, pusher boats and tugs with nozzles, VEEM offer traditional designs
such as the Kaplan, however our new Skewplan and Maxifoil Skewplan
designs offer the ultimate in thrust, smoothness and efficiency. Low speed
work boats without nozzles fitted benefit from either the Loadstar or
VEEMStar designs, both providing excellent thrust and manoeuvrability.
Cray boats, pilot boats, offshore supply vessels and other medium to high
speed commercial vessels with open propellers benefit from either the
VEEMStar or VEEMStar C designs, both offering smooth, fast and efficient
operation.
While ensuring maximum thrust and smoothness, VEEM’s fishing and work
boat propeller designs also prevent common problems such as cavitation
burn and poor manoeuvrability. VEEM’s design and selection skills ensure
