A boat-adventure operator working the granite cliffs and sea caves of Cape Woolamai that can only be reached from the water. The signature 30-minute Thundercat run comes with commentary from a skipper who goes by Captain Risky, while the Waverider tour seats you motorbike-style for a faster ride. There is a diving arm too, with PADI-qualified guides leading Discover Scuba sessions and guided sea-scooter tours. Boats leave from the San Remo jetty, with a second booth over at Cowes.
