Take the following as truth:  Formentera, Ibiza's diminutive neighbour just one hour's ferry-boat ride (or 25 minutes by hydrofoil) to the south, is an island apart in some ways more like a desert island than a satellite or outpost of Ibiza.
Then the following statement: "Hydrofoil is a faster means of travelling between the two locations, although ferry-boat is significantly more popular." is true, false, or inconclusive?
Answer: Inconclusive
