1. You can just go sailing at any time without fussing with getting a crew together
2. Its a lot more economical than a yacht - don't you know we're in a recession?

4. Dinghies are more exciting than yachts - you are more in touch with the wind and waves, and really feel the speed

6. You can explore beautiful rivers and inlets where a yacht would be hard aground
Any more....?
