Shona boat leaves from Port Erin & has an excellent facebook page with info of all the sailings plus mobile numbers and contacting them was a breeze . I recommend checking and reserving . 12 is max number of passengers . We had flat calm seas and sailed for a landing at South Harbour for a 2 1/2 hr walk on The Calf . The guy showed us a map and had info about the wild life . There is no mobile signal on the calf . We saw Risso Dolphins , Seals , Rabbits , Razor Bills , Shearwaters , Black Gulls , Shags, Oyster Catchers , Guillemots to name a few . Price £25 .
