Yes Mary!

I was swarmed by a pod of good sized dolphins a few years back on an old hobie 18. They are right along side us, zooming past and darting directly across the bows with only inches to spare. We were moving at about 8 kts. At one point, one of them seemed to enjoy matching our speed while swimming between the hulls just in front of the main beam. What a site! At some point, another one thump against us somewhere along the port hull. An amazing day!

I've also hit a seal on that same boat. We were in a good breeze, boat has moving 15 kts easy. My rookie crew was mumbling something while facing forwards...I could not make out the words over the sound of the wind. Moments later...THUMP! "What was that?!" I asked..."The SEAL!" came the reply...."Didn't you hear my warning you??"
