Two rods in your yak? If so a spinnerbait and a worm(texas rigged, since c-rigs suck from the confines of a yak) use the spinnerbait to find any aggressive fish, and the worm, along with looking at the above water topography to learn what's under the waters surface (points, drops, ditches, brushpiles, rocks, etc..). A carolina rig is better to me for feeling out a lake but the texas rig will do. I'm guessing you will be going back so use this trip as an opportunity to get comfortable with your boat, figure out what mods need to be done, and learn a little bout the lake. There was a time not that long ago, electronics were rarely seen in boats...yet people still caught fish. Good luck in your new boat!
