2025 Inmar 530RHD Base

Inmar 530RHD Military-Grade Inflatable 

Yamaha 40HP EFI

The Inmar 530RHD (17' 8") is engineered for extreme durability and high-capacity missions. Featuring a reinforced 1.2mm "Hypertex" hull and a heavy-duty non-skid aluminum floor system, this boat is designed to be beached on rocky shores and operated in demanding coastal environments. This is a rare opportunity to own a professionally rigged, late-model SIB that offers more deck space and stability than almost any traditional hull of its size.
