Not very successful. Irregular low wind conditions. Test got disturbed by ferries.
The boat is hard to maneuver and recover, pull off the water / carry around
The currents were often faster than how much the boat could sail, we had little control
The boat is tough, we launched in the water by throwing it 3 meters above water, without damage.
The electronics remained perfectly dried
We forgot the batteries (4AA 1.5V) and we could buy a set of batteries at the corner shop - that’s a very convenient battery pack.
The boat was a little too big to take around in public transportation (Hong Kong MTR)
