A full ten years before the thruster emerged, McTavish broke hull tradition with a narrow-nosed Morey Pope model called the "Big Mac."
(Yes, this is a real print ad for the Big Mac that ran in Surfer Magazine. Bob assumed the role of Captain McTavish for the photo shoot.)
"Big Mac," obviously, was derived from Bob's last name juxtaposed with the newly-minted McDonalds hamburger. And to drive the point home, there was a big image of a hamburger laminated on the decks of this Morey-Pope model. It wasn't a big seller!
Ben Lexan designed a no-nose hull for Shane Horan in the 80's. While not a true hull -- it was only rolled a bit under the nose -- the concept was similar.
The key word is "redundancy." Belly under the nose allows a full outline to lay into the face of a wave without sticking. A pulled-in nose does essentially the same thing. But together, it was overkill. There was nothing for the rider to drive off of...whether it be a parallel outline/full nose, or some edge on the front of a narrow-nose board. In the end, there was no benefit to applying both design concepts to one board.
