Re: Flying Scot - did I buy the wrong boat?
Don't give up on your Scot. Just buy a used smaller set of sails, like from a 14 or 15 foot boat, and keep using them until all of you guys are comfortable and have learned how to act on your boat when sailing. Smaller sails will make the boat more stable and less responsive - but in stronger winds you will still sail fast. Then you can go back to the big sails and have real fun. Scot is an awesome dinghy but it does require some skill to sail nicely.
Be kind, for everyone you meet is fighting a hard battle.
