Why would I want a sunfish?
Aside from cutting rope, and looking good while doing it?
If I get tired of my pants actually sitting at my waist and i want that "saggin" look. Nothing a few pounds of steel in the back pocket won't fix.
Sometimes when the current is too strong while fishing the Chattahoochee I like to use a Sunfish as an additional anchor to drag behind the boat. And if your motor gives out you can always paddle to shore with it.
A Sunfish doubles as a nice "pocket" garden hoe, spade, and/or shovel.
There ain't nothing like a fried eggs and bacon breakfast when camping. No need for a skillet, just whip out that Toenail hold the main blade over the fire and start cooking.
Lost your spatula? No problem when you carry a Sunfish (carry two for use as skillet and spatula simultaneously)
Ping Pong paddle
Signal mirror
Temporary license plate
etc...
