1) Pull a wire from the "jumper wire" that goes between the two 12v batteries. Call that wire the "tweener". It will show 12v between either the boat's 24v ground OR the 24v hot. Can plumb it into a normal 12v cig lighter unit. Will work fine and will also allow more "substantial" 12v accessories to be plugged in (Q-beams, 12v inflators for tubes, high powered marital aids, etc..).
2) Use a cheap switching power supply. Most cellphone cords ALREADY HAVE one built in (to drop to the phone battery's voltage). Chances are, it will work with 24v LIKE IT SITS. Make sure, though, that if you install a receptable that it is clearly marked 24v so somebody doesn't plug a 12v accessory into it (especially that marital aid..)
