Well two reasons, I was there when it was voted in and that was the agreement, now if someone wants to go to dun laorghie or sandycove I'm sure the level 2 would do, however you need your level 3 to go on the boyne and rivers like that because you follow ICU guidelines. If you put yourself in the position of assessing the level of a paddler yourself you really are opening a can of worms for yourself.
