Janousek JV 4-/+/x
The VEB shape is the best selling hull since it was first used in 1981. (The first production four is still in use at the original club it was supplied to on 30th April 1981!) The JV four is slightly shorter and wider than the Janousek Long Mould, which makes it comfortable and easy to sit, and lends itself to being suitable for any standard of oarsman/woman. This shape has achieved widespread success at various championships, Henley Royal Regatta and national regattas. |

Janousek JL 4+/-/x
Longer than the Janousek VEB 4, Janousek JL mould is also narrower. The shell performs very well as a quadruple scull but requires more attention to balance and therefore more suited to more experienced crews for sweep rowing. This mould is available in coxed and coxless forms for crews ranging from 60-110kg. The Janousek 4 /-/x Long hull has 11 hull sizes dependent upon crew weight. Each mould has a 5kg average crew weight allowance, which allows boats to be build more specifically, unlike many other boat builders. |

Janousek JS 4x/-
Similar to the FISA Short Pair/Double, the Janousek JS 4 is recognised as the fastest shape in its category for oarsmen and women between 60kg and 80kg. This shape is extremely popular with all categories of lightweight and junior rowing. In the past this hull shape has won number World Champion and Olympic medals, and continues to dominate both international and national rowing regattas. |

SCHOTTEL controllable-pitch propellers (SCP), manufactured by SCHOTTEL-Schiffsmaschinen GmbH (formerly WPM), are propulsion systems that can be used with almost any type of vessel. The power spectrum ranges from 600 kW to 30,000 kW, with propeller sizes varying between approximately 1.5 to 8.0 metres.
Advanced calculation methods allow the controllable-pitch propeller systems to be optimally adapted to the vessel’s hull form, thereby maximizing efficiency and minimizing noise generation.
The simple structure of the SCP guarantees a high level of user-friendliness, and the robust design keeps maintenance requirements to a minimum and ensures it a long service life. |

| Unlike a fixed propeller which efficiently transfers motor power in only a limited r.p.m. range, the Controllable Pitch Propeller guarantees optimal power transfer throughout the whole r.p.m. range of an engine. Advantages AWM-Controllable Pitch Propeller: more speed in calm sea, more power reserves in rough sea, lower fuel consumption, improved manoeuvring and the maximum power transfer throughout the whole r.p.m. range of an engine Advantages of low fuel consumption: Motor-sailing yachts and motorboats has to cope with changing sailingconditions and wether types. In contrast with Regatta yachts (they can get help from a Regatta organisation) motor-sailingyachts and motorboats have to have thrust in themeselves when something goes wrong. In this kind of situations AWM-Verstelbare Propellers are an extra safety. At the same time low fuelconsumption is important for the boatman, because with long boot expeditions filling stations are often not close by. |

Since the summer of 2007, inquiries from, both, our U.S. and global markets indicated a high demand for an alternate source of high quality stainless replacement propellers for the New Yamaha 350HP 4/stroke Motor. Currently, a full family of these products is available to include 3, 4, or 5-blades, left & right hand rotation, pitch ranges from 15 to 28 in 15.25 or 16.00 inches in diameter.
Due to heat exhaust and heavy torque loads on today’s propellers, the PowerTech Propeller for the Ym 350HP 4/stroke has the Cushion Lok Hub, specifically designed as a premium alternative to the classic press-in rubber hub. It allows for super soft forward and reverse engagement, maximum drive train protection, and is failure resistant.
