[PSUBS-MAILIST] buoyancy

[hank pronk]

Rick,
I agree the wood will be fine, it will take on water but not enough in one hr to hurt  your test.  I just went to my pocket ref to look up wood density.  Pine is around 25lb per cu ft.  I assume that's very dry wood.

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.

    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.
