Remember the Bertram 31 Moppie?

This is the boat that started the deep vee revolution for boats that go fast offshore. They can go in any weather is the often heard reputation when heavy water boating is being talked about. It is a boat that causes fond memories about how the boat runs in an inlet with conditions that include breaking waves and a contrary running tide.

You know the story, Dick Bertram saw naval designer C. Raymond Hunt’s new boat operating under easy handed control in big seas while they were competitive racing a sailboat. That was in 1958. By 1960, Bertram had a prototype 31’ boat built using the same hull shape ideas.

That boat, named Moppie, won the 1960 Miami-Nassau race, and set a record in some of the worst conditions of the running of that event’s history. That win and it’s follow-up publicity in the Miami Herald newspaper (or was it the write-up in Sports Illustrated?) stopped semi-vee bottomed offshore race boat design and started designers working on deep vee boat shapes for racing wins in open water. A deep v could win a powerboat race because it would stay together when it was rough.

A Moppie has 22 degrees of deadrise at her transom. Some other boat brands later were designed with 24 degrees. A Scarab 30’ has a 24 degree bottom. Much longer boats than 31’ use less deadrise. A Bertram 31 needs horsepower to run with decent speed due to the steep angle of vee in their bottom shape. She is a tender boat. She can be wet. Designers have since come up with solutions in their deep v designs to solve these issues.
