Doh! I meant Warthog. The hatch is a hatch mold and reciever that I made and cut down to work for the anchor locker hatch on my Seacraft. I used the full sized one for the bilge access hatch. They can be top mounted or flush mounted like I did. I didn't want to use the scroty cheap plastic Rabuds type on my boat so I spent about 40 hrs making my own molds and hatches. So much for getting smarter as you get older but I like the end result.
