Not to sound like your mother - but make sure you do not swim for it. Be sure you have a way to retrieve it safely before you launch that does not involve you going in the water. We lose too many good boaters swimming (especially in cold water) for a stalled or tangled boat that seemed close to shore. I have never seen a boat worth dying for.

And on a happier note - post some pics/video of your sons having a blast getting her wet!!
