This unique boat hatch is truly for all seasons and all winds. As you can see, it is a large round hatch made of Lexan, which is strong enough to stand on, easy to open and close and has never leaked. but what makes it so unique, is the ability to swivel it in any direction, to match the direction the wind is blowing over your boat, which may not be from the front of the boat when it is tied to a dock, or riding to the tide, and not the wind. You can even face it backwards, to extract air; what ever works best for the conditions. To raise it, just loosen the fitting as Dave is doing in the picture, raise it to the desired height, and tighten up the fitting. Yo change directions, put your fingers on the small fitting you see in the top of the picture, pull it loose from the wall of the hatch, swivel it where you wish the hatch to face and put it back in place. It is ridiculously simple and amazingly useful.As you can see from the upper picture, we have five of these hatches, two in the galley, two in the forward cabin, and one in the forward head. We can snap on plastic covers to keep out sun when no one is staying up forward, and we have mosquito netting that quickly snaps on all the hatches. This is not manufactured by any maker, although I think they are missing a chance in a lifetime, but we would be glad to give any further information for those wanting to make their own.
