This hatch is flushed but requires a recess on the deck. Once the recess is in place, however, the hatch is easy to install. The recess corresponds to the market standard dimensions, which means that it is incredibly easy to change hatch. The hatches consist of a tinted acrylic glass and a frame made out of a high-tech composite. The combination of clever construction and the unique innovation of a composite frame results in the lightest and most durable hatch on the market.
