FREQUENTLY ASKED QUESTIONS 1. You pretend that PEDAYAK is a concentrate of innovations, but what are these innovations compared to the Hobie Mirage or other hands-free kayaks that recently arrived on the market? Indeed, PEDAYAK has several major innovations compared to its competitors:     The excellent efficiency of propeller propulsion and direct shaft drive. The 2 side keels under the hull protect the propeller and rudder perfectly and allow PEDAYAK to beach, even at high speed. They also add stability and potentially opposes drift when sailing. The change from forward to reverse is done directly by retropedalling. The easy, precise and efficient steering system combining:  A rudder located just behind the propeller that "picks up" the water nets propelled on the rear,  A helm  A control stick located just under the hand, which can be installed on the right or left according to your preferences. The possibility of using a light sail with good performance under all wind directions thanks to its keels. The side tubes are used as handles to ensure a good fit for the user, but also to fix a lot of accessories: fishing rod holders, bags and pockets, sounder. Modularity: Thanks to the addition of an intermediate structure solidly bolted to the hull, it can become a catamaran (PEDAYAK DUO), a trimaran (PEDAYAK TRIO) or a prao (PEDAYAK PRAO and GRAND PRAO). This assembly is done in 15 minutes. The PEDAYAK is available in an electric version (PEDAYAK Electric) and, as an option, powered by photovoltaic panels (PEDAYAK SOLAR). It can also be fitted with a rig, making a total of 21 versions in the PEDAYAK range. 2. What is the advantage of a propeller propulsion over other hands-free systems such as flaps or oscillating planes? The current propellers are designed with an elaborate specific profile, like aircraft wings. They have a high efficiency and therefore allow higher performance than other propulsion systems. In addition, they also allow you to immediatly reverse by back-pedalling. In addition, a propeller has a continuous rotation motion which is more efficient than a back and forth motion suffering loss at the limits of the motion. In shipbuilding in general, no boats are all equipped with propellers, not with flaps. 3. Why is PEDAYAK 50% faster than an ordinary kayak ? Because:  The propeller is much more efficient than the paddle.  The thigh muscle is much more powerful than the arm muscle. Without going into complicated technical explanations, an ordinary kayak moves forward on the reaction to a paddle stroke, i.e. to a punctual sending of a certain volume of water over the stern. PEDAYAK is propelled by the lift of the propeller blade profile, like an aeroplane wing, rather than by the backward propulsion of a mass of water. That said, a kayak's performance is always a function of the user's physical strength and training. 4. On the photos, the seat is fixed at an obtuse angle. Can the seat position be adjusted to a right angle for fishing? This seat inclination corresponds to an optimal and ergonomic pedaling position with efficiency. The one that allows the greate

If you want a more upright position, for example for fishing, you can change the position of the back by adjusting the backrest. 5. Can the seat position be adjusted according to the user's size? The seat as such is not adjustable: we think it doesn't need to be. However, the distance between the seat and pedals can be adjusted in several ways:  Sliding more or less into the seat (from the « buttock to bottom » on the rear position to « buttock on forward »)  By using the adjustable backrest  By slipping a mere boat cushion in the back, available to all shipchandlers. Thus, all the users...

That said, even if it is not imperative, we recommend that our users comply with the safety rules of the French rule « 240 division », especially regarding the mandatory equipment for the 2 and 6 nautical miles limit off the coast. 13. Can the algae and seaweeds prevent the propeller from rotating? The weeds or water meadows generally pass through the propeller without hanging on it. Any anomaly on the propeller feels through the sensations of pedaling, and performance. If an unidentified object is still attached to the propeller, stop pedaling, let it go few seconds on its speed and then...

A small adaptation may be necessary: By attaching a neoprene boot to the pedal, allowing the foot to remain attached to the pedal, they can use the device perfectly, even if they cannot pedal on a regular road bike. PEDAYAK does not require any balance or minimum speed, and the pedaling is soft. The particularly stable PEDAYAK TRIO Electric has been adapted for people with disabilities under the name PEDAYAK HANDI. The whole PEDAYAK range is designed for sailing: PEDAYAK, PEDAYAK TRIO, PEDAYAK PRAO, GRAND PRAO and PEDAYAK DUO (with 1 or 2 rigs). PEDAYAK is a small 3.6 meters long boat only,...
