Cut a length of 2" PVC pipe about 12" to 18" long and store it in your rod locker. When nature calls, you can use this device to get enough distance over the side of the boat and not end up peeing all over your boat and carpet. When finished, go to the other side of the boat and rinse it out in the lake. Remember to aim with the wind and not into it and keep it angled slightly down.
Not sure if this has been posted or not but I brought it up at the Mid-West Rally and a few thought it was a good idea.
