1. You can cross the oceans and travel the world in a yacht - unlike a dinghy
2. Yachts are romantic, allowing you to sail your love off into the sunset or find a quiet cove to go skinny dipping in
3. Yachts are for grown ups: look you're no longer 14 and really can't fit under that dinghy's boom any more
4. You make make a cup of tea or mix a perfect G&T in a yacht while moving
5. Yachts stay upright and don't randomly tip you over into the water
6. You don't need a horrid clingy smelly wet suit
Any more....?
