Years ago, I purchased a used 2004 Pungo 140, which is/has been a fantastic boat for me. It was my first boat, and I couldn’t figure out why there was a single, long screw in the bow without anything attached to it. Over time, I figured out that this was a foam pillar (?). I’d like to make one to replace it, and I’m wondering if anyone knows the dimensions of my missing component.
I don’t know the details of the Pungo but it sounds a lot like how Old Town attached the foam piece in our boat. There was a foam support and also an aluminum piece that the screw threaded into that locked into a slot in the foam. The foam itself isn’t strong enough for the screw to hold in. It was wedged in tight and then drilled and screwed.
I took ours out as it offered little support and little floatation and replaced it with a deflated 18” yoga ball that I blew up in place letting it form to the hull. It came out to be a good location as a center foot support and didn’t interfere with the foot pegs. It holds itself in place but could be strapped across the foot peg rail screws.
My 140 duralite Pungo had one. It wouldn’t stay put, so I bought a 2 X 3 section of neoprene foam from CLC boat kit maker in Annapolis, MD. $35 ten years ago made two bulkheads. Made a pattern and cut out on a ban saw. Almost had enough for a 145 Tsunami front bulhead replacement, but it was 1/4 inch too short. Seal with Lexel clear sealant, after cleaning with solvent and using sandpaper to scuff contact area.
