In the late 90's I looked at several boats in Charleston, SC that were purchased by parents for their then student kids at Med School there. These were very lightly used, seldom sailed and in primo condition.
I wish I could get my boat to an affordable slip in Stamford, CT for the summer, as a ROOM there is $250 a week. Short term rentals are non-existent. I know, we just moved my junior son up for an internship.
If you are a busy student, and are used to typical dorm rooms, you will be excited to have a boat. They offer privacy, comfort and space unlike a dorm. Especially if you are there to sleep shower and shave and back to work or school.
You then have the added benefit of beautiful sunsets and an experience unlike others. I would consider it seriously as an option.
all the best
