For Ycrow. Visited the New Bedford Whaling Museum to answer your question about scale.
A mature male sperm whale is about 35-50 years old, 50-60 feet long and weighs between 43 and 45 tons. That would make him about two times longer than a whaleboat. A fully loaded whaleboat with crew ranged from slightly less than one ton to about a ton & a half according to material published in The Whaleboat by W. Ansel.
The pictures I took show a sperm whale skeleton next to a wooden whaleboat in the museum.
