Why on earth would you put an outboard on a high performance cat?
Some people have to traverse a long, narrow channel to get to the open water, and a small motor can be a big help.
We used to live on a canal, and with a Laser I could tack up or down the channel, but it would have been difficult with a cat. Paddling or sculling would be preferable, but probably not doable for me with a stiff headwind.
