Today I received the hatch for the Fafnir. It is bigger and heavier than I thought. It does look like nothing could damage it however.
It’s 35Lbs and I am worried about the weight above the waterline, especially that I also want to use bronze ports on the cabin sides and front. I might have to reduce their number and add a little weight in the keel…
Boat people, what do you think?
I wish the progress was on the boat itself, but I have been swamped lately and could not work on reinforcing the jig as planned. Good progress was made on the CAD files though with the cabin top, stern, windows and hatch. I just wanted to share this picture:

Hamilton Marine had a great deal on a Baier cast aluminum watertight hatch so I jumped on it. You can see it on the image above. The reason I decided to use a hatch is because most of the stories I read about small boats being lost at sea involve a flooded cabin. So I am replacing the original companionway with a commercial grade hatch. The opening is 24″x15″, and yes, most small life-rafts do fit nicely through the opening. I’ll just have to watch my diet!
The windows will come from New Found Metals. I will be using rectangular and round bronze ports. The only problem with using a heavy-duty hatch and windows is the weight above the waterline. Something will have to be done to counter that moment to make sure the boat has no trouble righting itself after a knock-down.
Now I need to build a scarfing jig to scarf the keelson and bottom plate. I must have the keelson and bottom plate on before the end of the month!
