SAFETY SEA CHEST-- A CLEAR CASE OF WHEN LESS IS MORE.
         A single point through the hull replaces ten individual holes-- In effect, increasing reliability ten-fold. With the clear plexiglass cover, finally it’s possible to see if the flow is proper instead of guessing. What’s more, any debris obstructing flow can now be cleared from within the hull. Eliminating the need to dive overboard. And in case of any emergency, the sea chest can be quickly shut off to allow for repairs.

From “Defining the Offshore Vessel” by Editors at Ocean Voyager magazine
               “Every opening through a boat’s hull has the potential to let in seawater and should be know and easily reached. [...] The ideal is to have as few through-hulls as possible.
               Commercial vessels make use of sea chests that use one main opening to the sea to feed various systems. If flooding is detected, the closure of the sea chest immediately shuts off all possible flooding.”
