To add on top of what has already been said...

When fishing for big fish on the bottom its important to keep your rod pointed to the front of the boat. If you keep it perpendicular with the boat and the line suddenly breaks it can send you on over the other side. You also want to make sure you have a rod long enough to reach over the bow of your kayak in case the fish goes under you.

And yes, sleigh rides are as fun as they look.
