I went on exactly ONE whale watching cruise off Plymouth, Mass years ago. One was enough. There was a group of whales (don't know what kind) about that size uncomfortably close to a Zodiac type boat. I thought we were just fine on a 50-60 foot vessel. It made you hold your breath to watch.
Until the Finback whale cruised past.
I was way in the back dangling my arm over the rail. Something ..... large ..... went by and nobody seemed to notice.
It came back.
Seems they have different markings down one side and I could see it better. Oh. My. God. We needed a bigger boat for sure. Even the crew was shocked and said they'd never seen that much activity all at once.
I will stay on dry land, thanks.
