Overview

Raised watertight hatches are strong and secure enclosures designed to be easily accessed when needed. They are universally used on all types of commercial vessels from tank barges, hopper barges, box barges, and push-boats to OSVs and larger commercial vessels. Their simple design and quality steel construction help them meet long-range range trouble-free service requirements in the harshest environments.
