We were there recently, and a bit disappointed by the marina's reaction to the problem.
Only other boat I saw tilted was a victoria quite near Silkies berth.
This boat was a bit scuffed on the pontoon two days running, and nobody bothered- it was eventually moved across to the neighbouring finger, so the lumps appear to be very localised.
The corner of the carpark nearest the pontoon was underwater at high tide as well.
