Translation of Lastschiff

No, it is a summer camp for teenagers between the age of 16 to 18. They spend 9-10 months of the year in the boarding school, first in the mountains, then near a sea in the local area. Some of them have work to do during the summer vacation.
I hope that I will have time to go skiing. Maybe it is even better to go at the end of the season. The doctor, however, did not give his diagnosis yet. If I cannot go I will have to find an alternative.
I'm glad as well, thanks for the suggestions. I had little time last week as we had many important meetings. I beg your pardon. Let us continue later. Many greetings from Germany.
