Translation of gelding in German

Then we did a boat trip which started somewhere in the delta and ended somewhere else in the delta. Each couple received a boat and an elderly lady had to row. I did not feel comfortable with that.
Our fisherman stopped the boat and his nine year old girl opened a box with souvenirs, clothes and hats. We were in the middle of a river not going anywhere and had to start buying things.
We found someone to fix our tire in Villa La Angostura, a village on the other side of the lake. We also ate lunch there and enjoyed the atmosphere of this little town, before moving on to the seven lakes drive.
