I had one of those radios, the brand name was "Eurgle". It is a knock-off of a KO Propo Helios EX-10 radio:

The Eurgle is actually a decent radio. You can also buy it from Hobbypartz, same radio different name:

The thing about this radio though, is it is a very complex computer radio and requires quite a good bit of attention and patience to get all the variables programmed correctly. It is really intended for racing cars that need umpteen adjustments to steering, braking, throttle management, etc. For a boat, it is way overkill.
