Zipwake – dynamic trim control system

[Andre]

Just had a pair of Interceptors 300 Series installed on my Parker 800 Baltic. The installation was done by Andy from the Sussex Boat Shop Group. Andy did a superb job. With twin diesel stern drive engines and two long range fuel tanks she was always heavy on the stern and took a bit too long for my liking to get onto the plane. Trim tabs were the answer only no space to fit them. Last months during my visit to the factory to discuss a new built I noticed that these were being fitted to some of the Parker boats. When I got back to the UK and made some measurements on the transom and looking up the product on the internet a quick decision was made. A week later a set of interceptors arrived. These were only fitted on Tuesday and yesterday I took the rib out into Southampton waters and out to Cowes and back. The zipwake interceptor system is fully automatic and is connected to the GPS on the rib. You must input the length, beam and weight of the craft. The weight can be modified pending how many passengers on board. I was amazed how much the performance was improved especially getting onto plane and this was immediately upon acceleration. I topped up an extra 200 ltrs of fuel in Cowes and this extra weight made no difference. I am now keen to test with a full load of 8/10 passengers but this will have to wait till better weather conditions say T-shirt weather

never seen these before so googled very interesting how just 30mm of blade causes enough to compensate at the side of trim tabs which are not as efficient.

Are they trim only or will they do heel as well.

You will find loads of information here Zipwake | Dynamic Trim-Control System

Sorry, I was being lazy. I've come across the Humphree system before albeit on fast ferries and I know you can get different configurations - manual, automatic trim control and full ride control.

I've now had a look and yes, depending on what system you choose you can get full ride control with the Zipwake.

Interestingly both Humphree and Zipwake are based in Sweden.

Mate's Zipwake system failed last trip out. One of the interceptors stuck down so he had to limp about 10 mls back back to the marina where it mysteriously started working again.

Now a "trust" issue.

and he was constantly having to piss about adjusting it

Cool, I was looking into these for my next boat build. Looks a little less obtrusive than the classic trim tabs.

I’d say one “failure” is not a reason to throw them under the bus.

Volvo Penta have been using this type of tab for many years.

Personally, I prefer long tabs - as in projecting rearwards a distance - because, as well as adding lift, they effectively lengthen the hull, plus the lift is more effective because the lever (tab) is longer.
However, if there's no space for conventional tabs these could be a satisfactory solution. I can see that covering the whole width of the transom would generate a lot of lift and give a pretty comprehensive trim control.
