Finish an existing boat deck opening with a custom Starboard deck hatch built around your measurements and intended use. This is a deck-access product for installations that need a fitted opening cover with configurable details instead of a one-size stock hatch. Choose the options that suit the opening and the way the hatch will be used, including available stiffeners, anti-skid score marks, pass-through bolts and nuts, and an integrated seal. The hatch is positioned as water-resistant or splash-resistant; it is not a watertight solution.

Review the selected options with the installer so the fasteners, sealant, and installation method suit the deck construction.
