I dont think Rib Safaris run out of Beaumaris. A guy out of Moelfre does though! The following info was taken from here:

www.ynysribs.fsnet.co.uk - Ynys Ribs - trips around the bay in a rigid inflatable boat (RIB) seating 12 passengers. They offer the opportunity to see the scenery and wildlife of the local area including the Dulas Island seals in an hour long exhilarating ride. I was told that by early summer 2004, they had already become a hit with visitors and are attracting attention from school groups and by people wishing to spread ashes! If you're interested, information and leaflets are available from Caban Laura, the food and drink kiosk in the car park by the beach.
