Kokanee from kayak or pontoon?

[ditchbanker]

I'd like to try kokanee, but it sounds like tolling is the name of the game. That's also a game I've never played. The only boat I've got is a fishing kayak. I also have access to a personal pontoon, although I'm not sure that it would have any edge over the kayak. Has anyone ever had luck trolling with a self propelled watercraft for kokes? Is it possible without a downrigger, or is that mandatory equipment?

Any input would be appreciated.
