Guests joining us on our Wednesday 10:00 Signature Cruise from Kawaihae got to see a variety of cetaceans. Our first sighting was of a lone humpback who spouted and then took a 20 minute breath-hold dive. After watching him surface again, we headed north and found two “smallish” humpbacks. They also were on long breath hold dives – 17 minutes. But after seeing them dive the first time, a pod of very active spinner dolphins came over to check us out. While they were jumping and spinning and leaping, the Humpbacks surfaced again (maybe to see what all the excitement was about?). We watched them amongst the dolphins…and then when they dove we watched the dolphins play all around us again. On our way back to the harbor, most of us got to see our lone whale from the beginning of the charter breach…and then we all saw another pod of playful spinner dolphins.

ocean, and comes up to breathe every couple of minutes. We call this behavior “logging’ as the whale looks a lot like a floating log.
Between our regularly scheduled cruises, our kid’s field trip cruises, and some private cruises, we ran 5 different Whale Watch Tours yesterday — with all those cruises, there are just too many details to send in an email. Suffice it to say, the majority of the pods we saw throughout the day were Mom/Baby/Escort pods. We did get to watch some pretty wild surface action on a couple of our trips, with competitive pods charging around the Mom/Baby duo. We saw tail lobs, peduncle throws, a couple of breaches and lots of spouts and dorsal fins too. We deployed our hydrophones several times throughout the day with mixed results. We were always able to hear the underwater chorus the whales listen to all day, but only a few times did we hear very loud singing (indicating close-by males). Based on what we were watching on the surface, the males close by to us were way too busy to stop and sing!
Have a great weekend,
Captain Claire’s Humpback Fact of the Day:Humpback Whales don’t sleep as soundly as we do — if they did, researchers believe that they’d drown. Humans breathe in response to carbon dioxide build-up in our blood, but Humpbacks and other marine mammals have to keep part of their brain awake at all times so they remember to breathe. When a Humpback sleeps, he floats just under the surface of the ocean, and comes up to breathe every couple of minutes. We call this behavior “logging’ as the whale looks a lot like a floating log.
