I really did not enjoy this one. The boys were sent on an old fashioned whaling ship to hunt whales. I dont buy that they would slaugjter innocent animals. I also dont get the character of the captain (grindle) who seemingly would be quite happy to see a 13yo boy plummet to his death or eaten by sharks, or flog Hal. Especially as they wrte guests. Their dad would surely not subject them to that. The captain did not really het his comeuppance at the end either other than not being allowed to command a ship again. He had shot at some of his crew earlier and murdered a crew member due to kheelhauling.

Also like the last book thete was no animal specimen collection, and wad basically just about hunting whales. The opposite to preserved and protecting the animals we have had in earlier books.

I think this is one of three i hadnt previously read, with Amazon Adventure and Arctic adventure. The book ends with the boys being sent to Africa for the forthcoming African Adventure.

I seem to remember the series hots up from here after the previois two rather disappointing stories. ( )

As far as I know I read all of these, as a child, younger than 10. I've just recorded a representative few here, on goodreads. Loved them at the time, but that's nearly 1/2 a century ago. ( )
