The "Mothquito"..

Strange looking mini foiler, say a la SuperFoiler style, but it  might work too. Press Release sent by Mothquito Sailing Catamaran. More information: www.mothquito.com &
An original minifoiler catamaran design with an innovative foiling system

The IIFS Foiling company enters into the flying boats nautical market with an innovative project that provides new systems and solutions to the high performance sail foiling world, thanks to IFS patented system (Increased Foiling System), that is the result of a hard work of I+D that will see its first application in the Mothquito, a concept which was born in 2015 and is currently in development and manufacturing to carry out his first sea trials next spring 2018.

The Mothquito, which is the name in honor of the pioneers minifoilers, the MOTH International, for their close relationship in terms of size and appearance, is a high performance flying catamaran one-design with an innovative design and full carbon construction, which it's also able to increase its stability and dynamic performance thanks to the IFS system, a system that increases its dynamics length and beam, to achieve a significant increase righting moment (reducing heeling) and a decrease in pitch-pole risk, which in turn enables to oversize its sail area equating to benefits boats of greater length, but with less weight, which promises high speeds, with the maximum control and safety.

In short, it's a surprising foiling catamaran, fast and easy foiling to handle for any sailor regardless of their physical shape or technical knowledge, even for those who thought flying would be impossible for them.

Mothquito has an original and innovative hull design, with soft and organic lines, characterized by flat and curved bows upwards to minimize the risk of pitching that can cause pitch-pole, favoring the bounce on the surface without lost speed, and an hydrodynamic planing hull like high performance surf style, optimized to favor a quick takeoff facilitating the passage of waves under the hull, and a deck with an elevate forward, and work area with longitudinal stops (forward/backward) for sure footing on tacking at high speed, which in turn serve to house inside for a adjustable extensors arms of the T-Foils rudder. This hull design favors and provides a fast and effective transition with glide to foiling mode.

​But undoubtedly, the most striking in this boat is the innovative IFS system (Increased Foiling System). A system that implements and combines a number of solutions to significantly increase the dynamics length and beam of the boat, improveing longitudinal and transversal stability, to achieve increased performance with greater safety at high speeds.

The Mothquito incorporates a long foils in V facing outwards and provided with "double lift", whereby an increase of the dynamic beam up to 200% with respect to the sleeve hull is achieved, providing great lateral stability and a significant increase righting moment, which translates into a safer and more comfortable foiling with a considerable reduction in heeling. This allows the Mothquito to oversizes its sail area to equate to a larger boat, but with much less weight, which gives us an idea of the potential speed and adrenaline that offer this small flying insect of just 3.05 m length, able to increase its dynamic beam up to 4.80 m.

The IFS solution to increase dynamic length, is based on two advanced main V-foils and a extendable arms that can regulate the working distance of the T-foils rudder beyond the transom. This increases the distance between dynamic lift points (main V-foils and rudder T-foils), extending the boat length in flight too up to 50%, specifically 3.05 m hull length to 4, 50 m in length overall in flight. With this it´s possible to delay the weight of the crew to move the center of gravity further aft and to be able to regulate, correct and improve the dynamic trim or longitudinal balance with an improvement also in the rudder response.

Their foils in V have the advantage of auto-adjust the height navigation automatically without flaps or sensor, since the higher boat speed increases the lift force while the wet surface of the foil is reduced until the weight of the boat itself prevents the foils to go out of the water and collapse, thus automatically adjusting the height of foiling. In other words, if the boat rises too high, the submerged V provides less lift, while if the boat descends, the V submerges providing more lift and raising the boat again.

These foil in V also have two sines, the main or conventional sine V, and a second sine in the wingtip and directed downwards called by IFS as double lift, which has the function of increasing the lift due to its design, to reduce the transition time to flight mode. This double lift also acts as a barrier to minimize vortexes generated at the wingtips by difference preassures, subtracting performance. This solution also increases the safety of the boat, since these sharpened points facing down, do not pose a risk to the integrity of the crew in case of man overboard.

The Safe Foil System of IFS that is incorporate in the Mothquito, is an integrated box-foil with its lower outlet above the waterline. When hoisting the V-Foils, their wings are elevated above the waterline, allowing the Mothquito to beach without risk of damaging their foils by contact with the ground. This system also provides the possibility to launch the boat on the shore itself, without having to carry it to find enought draft because it also allows you to navigate with openwork minimally foils. Due to its small size and low weight the Mothquito can be transported over the car.

Currently the Mothquito is in the manufacturing phase and will carry out its first tests in spring. The IFS Foiling team is betting that this small minifoiler will be a true revolution, with a competitive price and capable of offering high doses of adrenaline and fun with maximum safety.

Seeing this boat, with their long V-foils facing outwards, the extension arms of their T-foils rudder protruding from the stern and wings as standard for hike out replacing the classic trapezes, then, the vision of a mosquito comes to mind, hence his designer Toni Blanc has baptised it with the name of Mothquito.
