Hatch-Deck
The deck features a 20" round hatch. This feature
is great for cabin ventilation and includes a custom
screen for insect protection.
The hatch placement permits a mate to to work
the deck hardware during inclement weather
and water conditions. Cleats and anchor locker
are safely accessible from the cabin for docking/
anchoring applications.
Close hatch and lock all latches against the frame
securely before making headway as the hatch
could become a visibility blocker from the helm
position. Supervise hatch use when children are
present.
Never step on the hatch while on the deck. Close
and lock the hatch each time you leave the vessel.
