Fendertex textile fenders are a revolutionary design and have been on the market for over 5 years. Fendertex Fenders can be found on some of the worlds largest yachts.  Fendertex Fenders are ultra lightweight, making them easier to handle than traditional PVC or other inflatable fenders (up to 40% lighter compared to other inflatable PVC fenders and 95% compared to traditional PVC fenders). Fendertex minimize storage footprint by deflating and rolling or folding (50% smaller compared to other inflatable PVC fenders and 95% smaller compared to traditional PVC fenders). Fendertex Fenders can compensate for temperature fluctuations, unlike other inflatable fenders and will maintain their shape after long periods of compression. 

The Packless Sealing System (PSS) Shaft Seal is a mechanical face seal created between a rotating stainless steel rotor and a stationary carbon stator. The carbon stator is attached to a convoluted rubber bellow and the back of the bellow is attached to the shaft log (sterntube) of the boat with hose clamps. During installation, the stainless steel rotor is used to compress the convoluted bellow. The rotor is then secured to the shaft. The compression of the bellow allows the seal faces to remain in constant contact while compensating for the fore-and-aft movement of the shaft caused by the propellers thrust pushing on the engine mounts. The carbon stator is bored slightly larger than the shaft diameter, allowing it to “float” around the shaft and compensate for most misalignment and vibration problems. The stainless steel rotor is sealed to the shaft with o-rings. These o-rings rotate with the shaft and rotor and do not experience any wear during operation. This static o-ring seal enables the PSS Shaft Seal to be fit on shafts that have some wear or pitting, unlike lip seal designs which require a clean area for the lip seal to ride on. This type of carbon face seal is not as sensitive to interruption of water flow or operation in silty water, when compared to other sealing options.

Max-Props are "feathering propellers", so unlike folding propellers, Max-Props do not rely on centrifugal force to open. Instead, the Max-Prop relies on the torque from the shaft rotation acting on the "differential" type gear design in the body of the propeller. This in turns ensures an immediate opening in forward and more importantly in reverse, unlike folding propellers which have a lag time in reverse. Through the years, Max-Prop propellers have acquired a flawless reputation for reliability and longevity. It is not uncommon to see a boat built in the 70's or 80's still using its orginally installed Max-Prop. A simple check on the internet would allow you to see the renowned reputation of Max-Prop. While we all wish that we could sail all the time, a propeller is a very important part of any sailboat. Sailboats end up powering a substantial amount of time and sometimes, in an emergency, we have to use our engine. In times like this it is critical to know that your propeller will open and will function as designed. Max-Prop has proven that time and again for decades.The simple fact that the Max-Prop blades use the same leading edge and pitch in reverse as in forward results in an identical power in both directions. A fixed blade propeller looses almost 50% of its power in reverse. Worse yet - a folding propeller which, depending on the brand, can loose up to 80% of its power in reverse. The MaxProp blades switch from forward to reverse instantaneously. It takes only ¾ of the shaft rotation for the blade switch to occur. 

KiwiGrip is a revolutionary, water-based non-skid coating. It is easily applied and extremely durable when fully cured. KiwiGrip provides a beautiful, ustomizable texture and color that can be applied over a variety of substrates. After preparing the substrate, KiwiGrip is spread with a foam brush or notched trowel over the application area. A roller is then used to provide the desired texture (no fillers or aggregates needed). As the delivery agent (water) evaporates, the plastic acrylic resin will fuse together and form a strong, durable non-skid coating. KiwiGrip is flexible after drying and effortlessly covers minor imperfections in the substrate.
Unlike other non-skid systems that require sand or other media to provide texture, there are no aggregates found in KiwiGrip. This feature provides several advantages for choosing KiwiGrip over the “filler” based non-skid coatings:
• More consistent finished texture during application
• No "craters" due to the filler being released as the top
coat wears away
• No crazing (surface cracks) or fractures due to flexing,
expansion or contraction

SoniHull produces a pattern of alternating positive and negative pressure, whereby the microscopic bubbles that are created during the negative pressure are imploded when positive pressure is applied. This implosion has a cleansing effect that destroys algae, the first link of the food chain, making the surface less attractive to other marine life that feed on the algae. This microscopic movement of water also prevents barnacle and mussel larvae from embedding. Transducers are placed near the vessel centerline and about twelve inches or more away from structures like primary bulkheads. As the beam of a boat approaches 20 feet the transducers will need to be positioned further outboard while reducing the fore & aft separation. A distance of 25 – 35 feet apart will provide effective and efficient hull protection.
