Frequently Asked Questions about the Zipwake System
What is the price difference between Zipwake and conventional trim tabs?
The Zipwake intercept system generally comes at a higher price point than traditional manually operated trim tabs. However, when adding the same automatic functionality to a traditional trim tab system, the costs become comparable to or slightly higher than those of Zipwake for the same boat.
For what types of boats are the Zipwake systems suitable?
Zipwake offers two different series of products, namely Series S and Series E. These product ranges are designed to cater to boats ranging from 20 feet (6.10m) to 100 feet (30.48m).
Series S: For boats ranging from 20 feet (6.10m) to 60 feet (18.29m).
Series E: For boats ranging from 50 feet (15.24m) to 100 feet (30.48m).
At what speeds are Zipwake interceptors effective?
Zipwake interceptors perform optimally on fast and semi-planing boats. Boats traveling at speeds less than 10 knots are likely to experience less pronounced benefits from the Zipwake system. For very fast boats, it is relevant to note that the interceptors self-protect against damage at speeds above 60 knots by automatically retracting, contributing to the durability of the system.
Do Zipwake interceptors create resistance and reduce boat speed?
Technically, any component attached to a boat below the waterline creates some level of resistance. However, the small blades of Zipwake interceptors, measuring 30 mm for Series S interceptors and 60 mm for Series E interceptors, minimize this resistance significantly. Notably, extensive tests show that the Zipwake system, when used in comparison to systems without interceptors, can even demonstrate a slight increase in speed, thanks in part to the efficient lift generation at the transom.
What power supply is required for a Zipwake system?
All Zipwake systems are designed to operate on direct current (DC) electrical power, and they operate in the broad range of 12-32 VDC. This makes the system compatible with most electrical systems on board boats and provides flexibility in terms of power sources.
What do the numbers in the name of a Zipwake system mean?
In the name of a Zipwake system, for example, the Dynamic Trim Tabs Series 600-E kit, the numbers refer to the width of the interceptors in millimeters. This specific kit includes two interceptors of 600 mm each. This precise dimension designation makes it easy for boat owners to choose the right product based on their boat specifications.
How many interceptors does my boat need?
Zipwake systems can accommodate up to six interceptors on a single boat, with three on each side of the centerline. In many cases, you may not need six interceptors, and two or four may be sufficient. The required quantity can be determined by the extent to which the boat’s transom can be covered by interceptors. Zipwake recommends covering at least 30% of the transom width, but experience shows that installations with 50% or more of the transom perform optimally. Completing the Zipwake questionnaire for specific boat details provides the best guidance in determining the number of interceptors needed.
Can I mount interceptors in the locations where trim tabs were previously?
In general, it is advisable to mount Zipwake interceptors directly on the transom to generate the most lift as far back in the boat as possible. This usually involves removing the recessed trim tab and filling the indentation with fiberglass. However, depending on the depth of the recess, there are cases where this may not be necessary, allowing for some flexibility in the installation procedure.
Can I manually operate a Zipwake system?
Zipwake systems feature the option of manual control using the two wheels on the control panel. Nevertheless, the majority of owners prefer the automatic mode, where the system adjusts the interceptors on its own based on sea conditions and weight distribution on board. This eliminates the need for constant manual adjustments of the interceptors.
Does Zipwake need to be connected to an external GPS?
The control panel for all Zipwake systems is equipped with a built-in GPS, accelerometer, and solid-state gyro sensor. This allows the system to accurately track all movements of the boat on its own. For specific situations where on-board obstacles might hinder the reception of the GPS signal, an open NMEA 2000 port is available to connect the system to an external GPS. This adaptation provides a solution for various navigation conditions.
What seasonal maintenance is required for Zipwake?
Zipwake interceptors are characterized by a remarkable level of maintenance-free operation. To maintain optimal performance, the interceptors should be periodically cleaned of any marine growth. An additional step involves painting the interceptors with the same antifouling used on the hull, with a frequency corresponding to hull painting. In the case that the boat is continuously in the water, it is advised to annually remove the front plate and flush away any marine growth from the inside. For an even more effective approach to marine growth, the “Auto-Clean” function is available. This function ensures that the interceptor blades periodically extend and retract to minimize fouling. It is a recommended practice for owners to be aware of seasonal maintenance to ensure the durability of the system.
Are software updates and electrical maintenance necessary for Zipwake?
In addition to physical maintenance, the upkeep of the Zipwake system also involves software updates. These updates can be easily performed by downloading the latest software from the Zipwake website onto a USB stick, which is then inserted into the back of the control panel. This ensures that the system stays up-to-date with the latest features and performance improvements. Like any other electrical system on board, it is advisable to periodically check and clean the electrical connections, especially if there are signs of corrosion. This ensures consistent and reliable operation of the Zipwake system.
Can the Zipwake system be repaired?
A reassuring aspect of the Zipwake system is that each individual component is repairable. In the event of damage, it is not necessary to replace the entire system. The interceptor consists of a front plate, including the blade, a servo motor, and a rear plate mounted on the transom. For example, if a blade is damaged, only the front plate needs to be replaced. Similarly, a faulty servo motor can be replaced separately. This avoids unnecessary costs and makes repairs efficient and cost-effective.
What is the difference between straight, V-shaped, chine, and tunnel interceptors?
Zipwake offers various types of interceptors to meet diverse needs. Straight interceptors have the standard rectangular shape and are commonly installed. V-shaped interceptor blades have a V-shape and are designed to be mounted straight on the boat’s centerline, resulting in additional lift. Chine interceptors have angled blades on the outboard side and are used on boats with a reversed chine. The blade angle is 20 degrees, except for the Series E 600 Chine, which has a 15-degree angle. Tunnel interceptors have curved blades and are installed above a propeller tunnel on boats that have one. This diversity of interceptor options allows boat owners to choose the most suitable type based on their specific boat design and performance needs.
Does Zipwake improve fuel efficiency?
A notable benefit of the Zipwake system is the potential improvement in fuel efficiency. After extensive testing, Zipwake has identified an average fuel savings of 4% to 9% when using the Zipwake system in Automatic mode. These savings may vary depending on the boat’s cruising speed. However, it’s essential to note that each boat is unique, and results can fluctuate based on different environmental factors and sea conditions. Nonetheless, the fuel efficiency of the Zipwake system provides a valuable advantage for boat owners, especially those who regularly cover long distances.
