It is the adrenalin rush of driving the boat at a reasonable speed in a strong cross wind an angle towrds a set of sharp poles welded together, set at an angle on a slippery slope, knowing that if you screw up you either:
1) scratch or hole the boat
2) impale your son who is waiting beside the trailer to hook on
3) if that is not enough, drive the nose of the boat into the back of the Peugeot
all the while being watched by a group of fascinated 10 year olds in Oppie's and their parents just waiting for you to horlix it.
But it only takes a few minutes from house to Berthon to the quay and down the river.......
