Eelman ,
Both the Scarby ramps are about as safe they can be ,no guarantees.
If the overnight conditions are good both ramps will pretty much run all night with early starters and late finishers from the day before , you can view that as good and bad I spose.
I have not heard of major problems but I'm sure it would have happened at some point. I reckon the Boat Club side would be better as it is less isolated.
