 Brain, really?  I better do a test.  Good to know.  Hank

 Hank , those buckets will collapse with very little pressure.    I did a test with my sub and there was not much depth but the bucket collapsed.

 Tim, My concern is about not having buoyancy inside the hull.  I am just wondering if there is any reason putting air tight buckets inside the hull could be a problem.  Maybe for inspections?  Seems like a good idea to me-given the low cost and the insurance of not sinking.Hank

Hank,

Fill the buckets with solid foam.  That should solve your concern.  There are loads of barges out there made with solid foam blocks between the bulkhead frames.

Hi All, after talking about it for years I have finally started building my sub launching landing craft.  I abandoned the barge idea for logistic reasons.  I am repurposing the hull from my paddle wheel boat.  I am well under way and should have the hull mods done in a week or so.  I was planning to use an A- frame to lift the sub into the water.  I have changed my mind and am sloping the front deck into the water and making a strong  fold down ramp \ door to just winch the sub onto the deck.  

I am new to this and am very paranoid on these huge lakes.  There are a lot of boats on the bottom!  My plan was to fill the hull void with plastic drums to make it un-sinkable.  I can not source barrels close to home-I can get 150 5 gallon plastic buckets for 150 dollars.  I am thinking of filling the hull void with buckets.  Any reason this is a bad idea?  I will leave a crawl space down the middle for inspection purposes.

Hank
