From what I can gather by visiting the website ZIPWAKE.COM, the product is from Sweden and dates back to 2014. The mechanisms attach to the transom of the hull, and operate to lower or raise an "interceptor" or vertical blade into the water stream coming off the hull at the transom. A servo system controls the interceptor blade extension or retraction, and the system appears to be able to very rapidly alter the amount of blade inserted into the water stream to correct for pitch and lateral trim on the boat. The system control unit needs to be mounted very close to the hull centerline, as that unit appears to contain the sensor that can deduce change in the pitch and trim on the hull. A GNSS sensor is also need to input boat speed, as the servo control mechanism apparently includes boat speed into its algorithm of how much depth to insert the interceptor blade into the water. At low boat speeds more blade insertion is used than at higher boats speeds.
One problem I anticipate with installation of these interceptor devices on the transom of a Boston Whaler boat's Unibond hull is the need to have substantial embedded backing material in the location where the interceptor and the adaptor plate or backing will be located. The transom surface at the location of installation of the backing plate must be completely flat. This could also be a problem on some Boston Whaler hull transoms.
Each unit requires six or eight or 12 machine screw fasteners to attach to the hull, and at least two units will be needed.The diameter of the drilled holes will be 3/16-inch or 5-mm. A control cable must be connected to each unit. If the cable is to be routed through the transom, an addition hole of 3/4-inch-diameter through the transom must be made; otherwise the control cable can be run up the transom and over the transom.
The instructions indicate the installer is to "prepare for machine screws per [boat] builder preference." The preference of Boston Whaler for their Unibond hulls is probably not for the owner to drill 12 to 24 holes in the transom of his Unibond hull, at least not without probably voiding the ten-year-warranty on the hull against defects in manufacturing. For boats with conventional hulls, the adaptor units are to be through-bolted onto the transom. Through-bolting won't be possible in most installations on a Unibond hull.
When the blades of the interceptors are lowered into the water stream, they are going to be subject to significant forces tending to pry them off the transom. So the attachment to the transom must be very strong.
I suspect that the difficulty in attaching the interceptor blade units and their hull adaptors to a Unibond hull may influence their use on a Boston Whaler Unibond hull boat. If Boston Whaler were to adopt these mechanisms, they would probably modify the hull construction to provide very strong embedded material into which the adaptors would be fastened by multiple machine screws threading into tapped holes in the embedded material.
I was a bit disappointed with the ZIPWAKE website because it did not show their product as installed on a boat with the boat out of the water so a clear view of the installation could be seen.
I found a very short youTube recording that does show the interceptor devices on a boat transom:

Center Consoles Only, and demonstrates the installation on the transom-mounted interceptor devices: See
https://www.youtube.com/watch?v=ZtBBOfyRrG8The actual installation only covers the mounting of the interceptors on the transom. This ends at 17-minutes 40-seconds into the presentation. After that no further installation is shown, and the presentation jumps to a demonstration of the use of the ZIPWAKE. During installation it appears that the machine screws fasteners are just driven into the transom and not through bolted. Or, if they were later through bolted, it is not demonstrated. Almost all the fasteners must be tightened to specific torque values, so a very accurate torque wrench (or two) is needed.
Also in the interceptor installation presentation, a MAJOR amount of work was skipped over. The surface plane onto which the backing plate or adaptor plate is to be mounted must be perfectly flat. This is probably required to prevent any binding of the mechanism contained in the backing plate or the interceptor module. Both seem to be molded of a thermoplastic material.
On the particular hull in the presentation, the installation apparently required that the gel coat layer on the transom, in the area where the backing plate was to be installed, had to be ground to create a rough surface, then the area was built up with epoxy resin and filler, and then faired to be perfectly flat. The epoxy build up has a wedge shape, thicker at the bottom than at the top, which apparently is needed to get the orientation of the backing plate to be more orthogonal to the hull running surface. This is not shown or explained in the presentation, but someone (evidently familiar with the product and its installation) explains the skipped steps in the comment sections. They describe the omitted part of the installation as "the most labor intensive part of the installation." (I can see why the tedious labor and transom modification needed was omitted; the presentation seems intended to be entirely positive regarding the ZIPWAKE product.)
The comments from viewers of the presentation include several very negative remarks about the ZIPWAKE system. Of course, that is to be expected on any sort of open comment situation on the internet.
The ZIPWAKE system seems like a re-invention of the Volvo QL trim system that was introduced in c.2008, also from a Swedish company. I believe that Boston Whaler at that time actually offered the Volvo QL trim system as an option on their 230 DAUNTLESS model. The Volvo QL trim tab system was discussed at that time in a thread on the old forum. This thread is still archived--like all threads from the old forum--and has some interesting comments. See
