🔒 ENCLOSED BOW ADVANTAGE (SOVEREIGN EXCLUSIVE)

Unlike the open-bow Viper Cat models, the Sovereign 400 features a fully enclosed forward section, delivering:

☑ Dramatically reduced spray and splash
☑ Increased passenger comfort on longer runs
☑ Improved protection for gear and children
☑ Greater confidence in rougher conditions
☑ A more “boat-like” ride feel

Perfect for families, offshore transitions, and buyers upgrading from open inflatable designs.
