Type of wood used for spine?

[phatdaddy]

Like Skunk, never seen one with a keel. Does yours have a belly tank or the saddle tanks?
All the ones I have messed with had the belly tank

based on what I've seen with general boat construction, including my own V20, teh wood is merely there for teh glass to fit over, creating a box type structure. There's no structural value for the wood itself, more so the glass covering it. Ive seen several boat manufactures using 1/3 cut pvc tubing in the bilge and covering it in glass, the glass itself creates a rigid chamber, the pvc just gives it shape. It allows water to drain thru that channel, even more so if you put limber holes in it for each bulkhead area.

My v20 has a belly tank. Stingers were not plywood, they were solid wood boards. The spine is solid wood as well. The bulkheads were a mix of plywood or solid wood. There was a PVC tube for drainage that ran alongside the spine from the cabin area to splash well area. I tried to post pics but I’m having trouble reducing the size.

I’m going to assume that I used the wrong term “spine/keel” in my original post to describe the area I’m replacing next. Follow the link for a short video of the area, the “spine”, that I’m replacing next. https://youtube.com/shorts/uz15niL94O4?feature=share.

Are you sure that what you're calling a spine isn't a Stringer? Solid wood standing upright running the length of the boat?
