The Santorin has a pedestal seat. Ours sits on the pedestal post (not bolted) and therefore does 2 handy things.
1. It can be lifted off at anchor and gives more cockpit space
2. It swivels, so that when heeled you can turn the seat so your back is always dead downhill.
No problems with the fitting, but the moulded base support does give it the strength required.
