Two Different Tools for Two Different Jobs
HobbyWater makes more than one thruster. The Y02D is designed for kayaks, paddle boards, and small watercraft—steerable, lightweight, and built for recreational and fishing use. The TD Series is designed for ROVs, AUVs, and industrial applications—higher thrust, deeper depth ratings, and built for integration.
Comparing them is not about which is "better." It is about which is right for your application. This guide breaks down the differences.
Y02D: The Steerable Thruster for Small Watercraft
What it is: A servo-steered electric thruster designed for kayaks, paddle boards, and small boats.
Key specifications:
-
500W brushless motor
-
11 kg maximum thrust
-
Approximately 35 degrees of steering deflection
-
Approximately 2 kg unit weight
-
Fully sealed servo housing
-
Reinforced anti-impact beam
-
Matched battery option available at checkout
Best for:
-
Kayak anglers who want hands-free steering
-
Paddle boarders who need assistance against wind and current
-
Small boat users who value precision maneuvering
-
Anyone who wants integrated steering without a separate rudder
Not ideal for:
-
Deep-water applications (beyond recreational depths)
-
Heavy loads or strong currents requiring higher thrust
-
ROV or AUV integration
TD Series: The Workhorse for ROVs and Industrial Use
What it is: A series of brushless thrusters designed for underwater robots, ROVs, AUVs, and industrial applications.
Key specifications (TD30E as example):
-
Higher thrust output (up to 15 kg or more depending on model)
-
Integrated ESC (electronic speed controller) built into the housing
-
Pressure-rated housings for deeper operation
-
Customizable mounting options
-
Designed for integration into ROV frames and AUV hulls
Best for:
-
ROV manufacturers and builders
-
AUV integration
-
Industrial inspection and survey
-
Deep-water applications
-
Users who need higher thrust for larger platforms
Not ideal for:
-
Kayak or paddle board use (overkill for recreational applications)
-
Users who need integrated steering (TD Series is fixed-direction)
-
Applications where lightweight portability is critical
Side-by-Side Comparison
| Factor | Y02D | TD Series |
|---|---|---|
| Primary use | Kayaks, paddle boards, small boats | ROVs, AUVs, industrial |
| Steering | Integrated servo steering (~35°) | Fixed direction |
| Thrust | 11kg | 15 kg+ (model dependent) |
| Weight | ~2 kg | Heavier (model dependent) |
| Depth rating | Recreational depths | Pressure-rated for deeper operation |
| ESC | Integrated | Integrated (TD30E) or external |
| Mounting | Bracket for kayaks/boats | Customizable for ROV/AUV frames |
| Battery | Matched option available | User-selected |
| Target user | Anglers, paddlers, recreational | ROV builders, researchers, industrial |
How to Choose
Choose the Y02D if:
-
You are rigging a kayak, paddle board, or small boat
-
You want hands-free steering without a rudder
-
You fish or paddle in conditions where precision matters
-
You value lightweight portability
-
You want a matched battery option for simplicity
Choose the TD Series if:
-
You are building or integrating an ROV or AUV
-
You need higher thrust for a larger platform
-
You need pressure-rated housings for deeper operation
-
You want customizable mounting for a custom frame
-
You do not need integrated steering
Can You Use Both?
Yes—for different purposes. Some users have a Y02D for their kayak and TD Series thrusters for their ROV. The two product lines serve different applications and do not compete.
The Bottom Line
The Y02D and TD Series are not competitors. They are different tools for different jobs.
The Y02D is for anglers and paddlers who want steerable, lightweight propulsion. The TD Series is for ROV builders and industrial users who need higher thrust and deeper depth ratings.
Choose the tool that matches your application—not the one with the biggest number on the spec sheet.
