A good idea to introduce people but what about follow up. I used to take a lot of people out for fun rides. Some were freaked out but all enjoyed the experieince as I always try to include them in the sailing process. The trick is follow up, getting them back out there before they just see it as a memory.
Clubs might have a couple of bangers that are working well, easy to sail and get them out there under their own steam. Then follow up again with help ( advice, location and inspection) buying own boat. I was at a loss when I looked for my first cat and had sailed monos a lot in younger days.
