I'd recommend this to anyone who is able to get there. The organisation and hospitality is fantastic, and you don't often get the opportunity to blast down a winding river for miles without getting arrested!
Would love to find the time next year to do this, trouble is my Italian is not up to much, so the document means little. I think it states the max length is 8.8m and max HP is 300?
So the 9m 500HP Parker is out then!
I also googled mapped the route and it appears that there is very little water in the upper part of the river!
