Orin Edson's Evviva is not the largest superyacht that was built out of composite materials.

Most modern superyachts have a steel hull with an aluminium superstructure. Older yachts were built completely out of steel.

Except for the steel/alu combination, some faster yachts like the ones from Oceanfast have an aluminium hull with a composite superstructure. As such, one can say that Greg Norman's Aussie Rules is the biggest yacht with an aluminium hull and the biggest yacht with a composite superstructure.

Evviva has hull and superstructure out of composite materials. She might be the biggest all-composite yacht built in North America but she's not the biggest in the world.

Two other, both of them Jon Bannenberg designed yachts, with hull and superstructure in composite materials are larger :

- the 1998, 163'39" Oceanfast THUNDER (see photo 1);
- the 1986, 181'00" Sterling Yacht SOUTHERN CROSS III (see photo 2)
