Sailing canoe rigs can be fun, and you might be able to find a decently cheap Sunfish or Laser and have loads of fun.

The plane one is a bit tougher.

Both great fun.

• Flying can be expensive and highly technical depending on where you are and what you fly. I had a blast while flying, got some good trips in, was able to give most of my family the experience. I gave it up when I had kids because of the priority change
• I suppose sailing too depending. I did some sailing out of Boston harbor and had a blast but they were bigger boats, more expensive. Actually the place I rented from organized extended trips down the coast and my regret was not taking any

If you’re based near a coastal city, register at the closest sailing club for training sessions they likely have Laser/ILCA Dinghys they’re very fun to sail.
