[PSUBS-MAILIST] buoyancy

[Land N Sea]

Thanks guy’s,

Yeh, I expected the wood to compress a bit but only a small amount which I don’t think is critical in this particular application and I have a bunch of it laying around the shop. If Hank’s right then I think I will try that as they are easy to fine tune with a saw, I just didn’t want to have to strap a bundle of them on. 
As far as the webbing between the pods and hull go, I hadn’t thought about the dry weight loading factor which is a good point. I had planned on welding a piece of ss round stock between the two ends opposite the drop weight ss round stock which would prevent them from wanting to flex in either direction but there would still be a pretty good point load where the pipes meet the hull when the boats out of the water. I just hate having to put all that heat into the two pressure hulls if I didn’t have to plus I would eliminate a water trap which is all ways a good thing. Thanks guy’s

That would be my guess, too.

  Maybe Vance can weigh in on this but, I suspect that those webs serve to evenly distribute shock loads for deck handling.

    I can't comment on the structural pros/cons but can tell you that the 600 plate is still in fine condition after 30+ years.  It bothers me as well since even after a good rainfall water collects there, but if properly painted it shouldn't be a big problem.  Maybe give it some extra coats in that area.

      I also mentioned the other week about my desire to omit the plate that is welded to the pressure hull and battery pod of a K-350 and was wondering if any one could comment on that.
