It's OK Frank, think garage, think shed, think who will help you launch it, think what size rig you would need for the trailer.
Now remember Frank if you can launch it and trailer it on your own, you will sail it more often.
Be carefull Frank, big boat lust is a disease that will have you confined to the darkness for years, you will lose contact with all your friends, your marrage and family will suffer, and finally by launch day you will have lost contact with why you built it and stay at home and polish it all the time.
Be carefull Frank that kind of thinking is dangerous.
