We did the half day morning whale watch trip. The marine biologist on board was very knowledgeable and could easily answer any questions. There was no shortage of whales that day, as well as some porpoises and even a very large sunfish.
Being a smaller boat, it was nice not having to try and fight your way to the side in order to see whatever wildlife was near the boat.
Even in August, it can get quite cold on the water. I would recommend pants and long sleeves minimum.
The only downside to the entire trip was the fog, which limited the visibility, but that was no fault of the company.
If anyone is looking to go whale watching in Menterey I highly recommend this company!
