Trying to decide between Zipwake and traditional trim tabs? Both systems improve boat trim, ride comfort and fuel efficiency — but they work very differently.
Below we compare performance, installation, efficiency and real-world usability to help you choose the right trim control system for your boat in NZ conditions.
How They Work
Traditional Trim Tabs
Trim tabs use hydraulic or electric actuators to lower metal plates beneath the transom. By pushing water downward, they lift the stern and adjust boat pitch.
Zipwake Dynamic Trim Control
Zipwake uses fast-acting vertical interceptors that extend downward only a few millimetres into the water flow. Instead of pushing large plates through water, they redirect flow efficiently to adjust pitch and roll.
Side-by-Side Comparison
| Feature | Zipwake | Traditional Trim Tabs |
|---|---|---|
| Response Speed | Extremely fast (instant adjustment) | Slower hydraulic/electric movement |
| Automatic Pitch & Roll | Yes – fully automatic dynamic control | Manual (some advanced systems offer auto) |
| Drag | Low drag interceptors | Higher drag due to large plates |
| Fuel Efficiency | Improved due to minimal drag | Improved, but less efficient than interceptors |
| Installation Complexity | Moderate DIY possible | Moderate (hydraulic systems more complex) |
| Maintenance | Minimal moving parts | Hydraulic fluid & mechanical parts |
| Price | Higher upfront cost | Lower upfront cost |
Performance in NZ Conditions
In short, sharp chop and variable swell — common around New Zealand coastlines — fast automatic correction can significantly improve ride comfort.
Zipwake continuously adjusts pitch and roll in real time. This is particularly noticeable when:
- Quartering into chop
- Running uneven loads
- Carrying passengers on one side
- Accelerating onto plane
Traditional trim tabs require more manual adjustment to achieve similar balance.
When Trim Tabs May Be Enough
Traditional trim tabs are still a solid option if:
- You’re on a tighter budget
- You prefer manual control
- Your boat operates mostly in calm conditions
- You are replacing an existing tab system
When Zipwake Is the Better Choice
Zipwake is often the better option if:
- You want automatic trim control
- You frequently fish or travel offshore
- You run in changing sea conditions
- You want maximum efficiency and comfort
- You value fast planing and improved fuel economy
Real-World Example
We run a Zipwake S Series system on our Surtees 610 Gamefisher here in NZ, and the improvement in planing speed and ride stability is significant.
For many trailer boats and offshore fishing setups, the automatic adjustment makes a noticeable difference.

Frequently Asked Questions
Is Zipwake better than trim tabs?
Zipwake offers faster response, automatic pitch and roll correction, and lower drag. Trim tabs are more affordable but require more manual control.
Is Zipwake worth the extra cost?
For offshore boats, fishing vessels and performance-focused setups, many boat owners find the improved ride and efficiency worth the investment.
Can I install Zipwake myself?
Competent DIY boat owners can install Zipwake systems. However, professional installation is recommended if you are unsure about drilling or marine wiring.
