If I were to sail inland, I would only do this sport (with a mountain board though).
Super cheap, can ride close to home, never get skunked (works in zero knots just like a bicycle!).
Extremely safe (low speeds, hop off), works over grass, dirt, asphalt.
Beginner super friendly, anyone can just stand on the board!
No getting getting wet, works below freezing.
First duck jibes, backwind sailing.
I mean I can go on and on.
