CONCEPT AND TECHNOLOGIES
THIS IS HOW WE DO IT!
01 SMARTKAT HULLS
DESIGNED FOR PERFORMANCE SAILING
Form follows function: Our customized hulls are engineered for maximum buoyancy and stability. The length is optimal for rapidly climbing towards the water surface and reaching full hull speed.
Bold is beautiful: A bold hull diameter of 53 cm makes a clear statement of which we are very proud. The result is an approximately 25% higher buoyancy than other inflatable catamarans. Now you know why they get called "Big Berta".
Best in class: Our extreme pressurized hulls with a maximum of 350 mbar set the benchmark for inflatable boats. The additional pressure reinforces the stiffness and increases the speed potential significantly due to less body movement. You will experience your boat going the extra mile during adventurous rides.
One concept – two opportunities: Within our range we give you the option to chose between two lengths of hull, depending on your sailing preference:
Hulls with 4,0 m (agility hulls): Advanced agility/maneuverability – made especially for fast maneuvers and ocean adventures/waves. It´s the lightest model we offer, and the one with the lowest volume to pack, but the trade-off is more splash, especially for the front rider.
Hulls with 5,0 m (racing hulls): Higher speed and more buoyancy support at the front of the catamaran, which stabilizes the boat under a strong back wind (reduces the duck-diving effect).
Material: The hulls are manufactured of a highly tear-resistant, fabric-strengthened polyester/fabric mixture (bonded PVC) for extreme light weight and secure buoyancy. The PVC is coated with a DTEX-1100 cover and UV protection for durability. Reinforced head and tail protection caps with friction coating give protection in the event of collision.
Two layers of fabric are "heat welded" between an exterior reinforcement band and an interior airtight band (similar to Zodiac boats). Where sections are subject to elevated stress (e.g. Power Frame intake and seams), the material is multi-layered to make it extremely robust.
Safety valves: State of the art Halkey-Roberts valves (from an innovative high-quality valve manufacturer in business since 1941), with double seal leak protection. Easy to operate and secures your safety at all times.
02 SMARTKAT POWERFRAME
03 THE TRAMPOLINE
Single-handed sailing in all weather conditions: Your cockpit is customized around you for single-handed sailing, giving you all the features you need to move quickly during maneuvers, with enough space to bring along a crew or all of your gear.
The details: Two integrated storage pockets tidy up the ropes and secure your daytrip essentials. Three attached foot straps support riding out for thrill seeking sailors looking for a bit of extra speed.
Stay dry - stay comfortable: The Smartkat experience is enhanced by our one-of-a-kind "Stay Dry Technology“. The skin-friendly mesh of the trampoline gives you and your crew a perfect grip during maneuvers while ensuring that water drains on contact. Our advanced fast drying process uses the ideal material for water-based sports.
04 THE RIGGING
IDEAL FORCE DISTRIBUTION: THE KEY TO SMARTKAT PERFORMANCE
In detail: The revolutionary spanning system above the waterline (unique for inflatable catamarans) achieves unmatched stability for the entire rigging. All forces get absorbed and balanced through the centerboard and the mast, which comprise two opposite-force triangles. This stops the hull and rigging from warping, even when riding on one hull.
The result: This patented innovation effectively disconnects of the entire rigging from the hulls. No forces from the body movement of the hulls are transferred into the rigging, and the reverse is also true. Strong wind and waves have no impact on the stability and tension of the rigging, even in rough conditions. Yes, you will definitely be able to go that extra mile.
Centerboard Force Triangle: The cable of our one-piece bowsprit, in combination with two downward-strapped steel cables, stabilizes the centerboard laterally to prevent vibrations.
Mast Force Triangle: The forestay and the two shrouds stabilize the mast and counter brace the centerboard construction. All wind forces stay completely within the rigging.
05 RUDDER AND CENTERBOARD
LET´S ANSWER THE MOST IMPORTANT QUESTION FIRST: WHY DOES THE SMARTKAT HAVE A CENTERBOARD?
Design: The rudder and the centerboard are installed the same way: At a slightly inclined angle and with smooth surfaces to optimize hydrodynamics. This is a major contributor to the extremely high draft stability of the Smartkat, and its capacity for precise maneuvers.
Material: Due to the high forces inherent under harsh conditions, the rudder and centerboard are manufactured in aluminum and strengthened with stainless steel inserts. The lower part of the rudder and centerboard are padded with robust PVC caps for ground collision protection.
Ground Protection Mechanism (GPM): The rudder and centerboard are constructed with an automatic quick-release mechanism which engages at ground contact to both save the Smartkat from damage and protect the environment.
06 DYNEEMA SHROUDS
Our shrouds are manufactured of "High Tech Dyneema", a material that is characterized as light, very strong, with minimal stretching and the ability to be formed into loops and splices without much loss of strength. These highly loadable special lines have the same tensile strength as steel cable with only one eighth of the weight.
More Information about Dyneema: Dyneema is an incredibly tough material with the highest impact strength of any thermoplastic presently made. Dyneema is up to 15 times more resistant to abrasion than carbon steel. The strength-to-weight ratio for this material ranges from 10 to 100 times greater than steel. We use it to support the Smartkat mast against the force of high winds.
07 PERFORMANCE MAST
MODULAR AND LIGHTWEIGHT
The ducts of the plug connections for the mast are further reinforced to give extra rigidity and strength while providing an improved bend curve.
Material: The mast pieces are made of tubular anodized aluminum profiles of equal length for ease of transportation.
Our focus is on a clean, aerodynamic sail shape. The result is a 5,9m2 fully battened main sail, which balances power, responsiveness and ultra-light weight for an unmatched wind range. While rigging, you can feel the feather-weight softness of the sail and can already imagine how beautifully it will fill.
The main sail is attached to the mast with double-layered Velcro. Easy to open and close, even in a strong wind.
Battens: The battens give you stability and responsiveness. They allow you to easily adjust the sail profile - curved profile at low wind, flat profile at strong wind. Especially in light wind conditions, it is important to set your sails with precision for maximum speed.
Boom: Performance boats need a boom. We feel strongly that this is a mandatory requirement, not an option. There’s no better way to improve sailing performance on a mobile catamaran, and it’s the only way to get a flat sail profile in a strong wind.
Material: The base for the main sail is Dacron. The black sail is made entirely of this material. Our orange sails are made of Dacron and an X-PLY section. Both materials promise durability and high tear-resistance. Manufacturing our sails out of these materials is what enables us to guarantee their longevity.
Dacron: Dacron gives the sails great resilience, high UV resistance, and accelerates drying.
X-PLY: This has a slightly higher resistance to UV exposure when compared to monofilms due to the adhesives used in lamination. X-PLY also provides extra bias support and improved tear strength.
09 JIB / GENOA WITH ROLLER FURLING
Details: The jib’s extra 4m2 of sail has the added advantage of improving the airflow to the main sail. Together, the two sails form an integrated aerodynamic system. The jib includes a small transparent window to give you a better view when maneuvering.
Material: The optimal material for the jib is Dacron. Only this material guarantees hassle-free operation and durability. To be properly furled, a sail must be flexible enough to wrap around a tight radius and Dacron delivers.
The theory: The jib is a triangular foresail that sits ahead of the catamaran. Its tack is fixed to the bowsprit and needs to be worked when tacking. As the clew of the jib is further aft than the mast (meaning the jib and mainsail overlap), it is called a “genoa”.
In general, the jib makes only a minor contribution to propulsion when compared to a main sail. Its crucial function is as an airfoil, increasing performance and overall stability by reducing turbulence on the main sail's leeward side.
