I'd like to go whale watching but my 11-yr-old son gets seasick pretty easily if the boat slows down and just bobs on the water. He got sick on the Lover's Beach/Land's End tour in the glass-bottomed boat. He does okay if it's a motorboat and moving at a good clip. Do the whale watching boats move fairly quickly? Which companies have the smaller, faster-moving boats? I read that you can see whales from shore, but I'm assuming that on the boats, you're that much closer. Is that correct?
