Different people like different things. My wife loves her underpowered but very forgiving Hobie 14. She crewed for me for a long time on a Hobie 18 and Tiger, but she wasn't confident enough to helm one of those boats for any length of time. Now she is really learning to sail and loving it.

Putting a newby on something as responsive as a Tiger is not necessarily a wise choice. I also knew a fellow who tried to learn on a Hobie 20. I kept telling him it was a two person boat but he thought he could handle it. He capsized and almost got himself crushed between the boat and a dock. He no longer sails a cat.
