Pedal Boat Plans

Don't laugh. I'm serious about this.
Can someone tell me where I may find plans for a 2 person pedal boat? I'm looking for the type that uses 2 pontoons with a paddle-wheel between them. Two people sit side-by-side, and pedal. I'm looking for something that can be built in plywood, about 8-10 feet long (length not critical).
I'm building this for the grand-kids, and also to keep grandpa out of grandmas hair for a while....

Thank you for your time.

There are a bunch here, you might take ideas from them and make your own version. The 'Showboat' one has bicycle power, but when enclosed it seems like a possible bad idea escape wise.The front rudder would also be vulnerable to beaching or just about anything.

Marty the Mallard boat is another possibility.

How'd your search turn out Ed?
Any viable leads on a paddle boat.
I've always liked the swan ones myself.
You could do a propeller easier, cheaper and better than a paddle wheel in my opinion.
