The morning is a slow succession of small moments building up to a whale of a time. By mid-afternoon we&rsquore at Gansbaai, or Goose Bay, where we board the Ivanhoe, a catamaran that will take us out to sea. It all starts out calmly enough. Jason, the &ldquokeptin&rdquo, stands up front, the best spot to spot whales. He reminds us not to feed the whales or respond to them. The sun is sharply overhead and the sea is burnt out. Clayton, man of many parts, starts laying out hors d&rsquooeuvres and filling glasses with champagne, presumably in anticipation of a sighting. Just as he gets up to serve the first round, the Ivanhoe heaves and lists to one side, then starts lurching from side to side. The hors d&rsquooeuvres collapse. The champagne is put away. Some of us turn a whiter shade of pale. We slide from one edge of our seat to the other, clinging on to the seatback for safety, while being sprayed with seawater. Slowly we start seeing fins, then black shapes, then a fluke comes out of the water and we know it&rsquos a whale. It&rsquos not dramatic, like seeing tigers in the wild. But it creeps up on you and there&rsquos something about these giant mammals that holds you. There are three whales beside the boat, southern right whales that come from Antarctica every summer. From July to November, when the whales are here, the boats do up to four trips a day. They also photograph the callosities, the unique wart-like bumps on the head of each whale, so they know how many have actually come. It&rsquos usually about a hundred.
