Well, Islanders aren't a "racing hull" per se, but "cruiser/racers". I think the PO had racing in mind over other adventures.
Funny story. I wanted to get a friend involved in sailing with me so I arranged for her to take a Lido 14 class with me to get her going. The first day she kept complaining that I was being too competitive with the other students and always trying to get ahead and be first to the turn or whatever. She exclaimed, "it's not a race, relax". Of course, with me anyway, it's ALWAYS a race even if the other sailors don't know it. Anyway, the a few lessons later and she's screaming at me "hurry up, there catching us/ahead of us, trim the sails!". Moral I guess; it's ALWAYS a race, even if you don't know it yet.
