Varifold Propellers have taken the market by storm. Regularly fitted by such notable yacht building names as Baltic, Swan, Wally, Moody and Oyster, the complete range of Varifolds has a model for cruiser racing and racing yachts of every size. Varifold is revolutionary in design and brings a revolution to the yachts they are fitted to. Radical reductions in noise and vibration and excellent performance under engine, both ahead and astern, are the result of the propellers unique design. Varifolds have proper helical pitch distribution, including pitch reduction towards the blade tip. This pitch reduction 'unloads' the blade tips and, combined with the skewed blades, greatly reduces noisy pressure pulses against a yachts hull. While some other folding propellers have a helical pitch shape, few have proper sections or pitch distribution. None, put all these requirements into a complete package, except Varifold.

A propeller is possibly the most essential component of a motorboat and very important for sailing boats too. It requires a lot of attention, both by the naval architect and by the propeller manufacturer. "Specialists", who are able to tell you "off the cuff" what type of propeller your boat requires, simply do not exist. VETUS makes good use of an especially developed computer programme, which ensures the determination of the exactly right propeller for your boat with the aid of some (correct) information, which we require from you.
What are the most important demands made upon a propeller?
Balance
If you bear in mind that a propeller is often rotating at 2.000 r.p.m. (which is more than 30 revolutions per second!), you will appreciate that a good propeller should be well-balanced. A difficult and time-consuming job. but an absolute "must" nonetheless.

A fixed propeller is a sure choice when you know which propeller is the optimum propeller for your application, and when there are no substantial variations in the speed and payload of your boat. Most pleasure boats, some sailboats and many professional vessels are equipped with fixed propellers. These propellers usually range from two-blade to five-blade depending on individual needs. West Mekan calculates and produces fixed propellers of diameters up to 1500mm, and also distributes fixed propellers from a range of manufacturers. Fixed propellers are suitable for speeds up to approximately 40 knots.
Modern motors, with high RPM rates that make the boat capable of reaching great speeds, can make it difficult to find a suitable standard fixed propeller. This because it is not an easy task to find the correct main parameters such as diameter of the propeller, design pitch, pitch distribution and blade area may with this type of propeller. A specially designed fixed propeller can therefore very well prove to be your best option. But even if the fixed propeller is specially designed, the result may not be satisfactory. Our Type FR propeller is a better and more secure choice in such cases.

The Type FR is a fixed adjustable propeller, and is the best choice when you do not know which propeller is the best for your boat, when a suitable fixed propeller is hard to find, or when there are special requirements to the propeller.
The Type FR propeller is easily adjusted to optimum pitch using two wrenches. Adjusting the propeller to optimum pitch ensures a correct load on the motor, while also providing maximum power and fuel efficiency. In addition, the cost of a Type FR propeller is low compared to buying several fixed propellers in order to find the best one for your application. The Type FR propeller has approximately the same efficiency as a fixed propeller, in some cases even exceeding the fixed propeller's efficiency. When adjusted, it is used in the same way as a fixed propeller.
Fixed adjustable propellers are used for all types of boats, and usually have three or four blades. West Mekan calculates and produces these propellers in diameters of up to 1500mm, for speeds up to approximately 40 knots.
Fixed adjustable propellers with more or fewer blades can be specially designed.

Fully machined Inboard propellers by Acme have revolutionized the propeller manufacturing industry. Acme's superior design, coupled with the 100% CNC process, positions Acme Propellers as the most efficient and consistently smooth performers in the world. Acme Inboard Propellers are engineered for quicker plane times, improved speeds and lower fuel consumption. However, the best news is that, with Acme, superior performance is NOT based on "the luck of the draw". Accuracy is built into the design and manufacturing process. This means that you will spend less time and money, testing and tuning, and more time with your boat in the water and a smile on your face.
All Acme Propellers are cast in our own North American foundry and then 100% CNC machined in one of our two QS-9000 manufacturing facilities.
Computer Numerically Controlled milling machines offer the most accurate and consistent means for removing metal and finishing a propeller to its correct dimensions. This method of production, relative to hand-finished, translates into Acme Propeller perfection and the elimination of one big variable in boat performance.
Acme is currently producing propellers up to 48 ” in diameter. Contact us to see if we have the perfect propeller for your boat and application.

This type of propulsion system is particularly suited
to working vessels (tow-boats, fishing boats, river
bargers and pusher tugs) in the sea and on
rivers.
The nozzles can be of two types: "Fixed" or "Rotating"
(Steering Nozzles).
The advantages gained are the following:
- Reduction of propeller diameter;
- Reduction of propeller shaft and stern tube diameter;
- Reduction in vibrations, expecially in the wider stern as the nozzle regulates the water flow; - Reduction in ship's pitching when in rough waters;
- Increase in the propeller thrust to the tow and to the Bollard-Pull;
- Possible increase of ship speed by approx. 15%;
- Better performance from heavily loaded propellers, especially in shallow water;
- At the same conditions of speed, trawler work, Bollard-Pull, need 30% less power engine;
- The smaller engine cost, the reduction of fuel consuption, the high-performance of trasmission allow to recover the investiment within one or two years.

For this application a variable plunger pump with a compensated pressure/ flow control and a limitable stroke volume should be used.
An electric generator set that is also fitted with a variable hydraulic plunger pump as shown here, is able to provide both hydraulic and electrical power and may therefore be genuinely called a multifunctional "powerpack . However, if the generator set is required to provide hydraulic power, under certain circumstances it may be that there is insufficient electrical power to meet demand, due to the limitations of the engine horsepower. In this
(case the electrical supply will be automatically locked out. Please see the relevant instruction manual. With a view to the fact that the pump stroke volume and operating pressure can be limited, the hydraulic output power may be limited to any maximum value, as required.
