Concrete ships

If I recall correctly one of the thesis projects at the Webb Institute of Naval Architecture for my daughter's class was building a concrete canoe.

I had a friend that built a concrete sailboat in the early seventies.  He left work, took has family on a sail voyage around the world in it!

Anyone who wants to model one, find a copy of Shipbuilders Cyclopedia, published in 1920. There are plans there. You might find a copy in a major library's reference section, or maybe through interlibrary loan.

Hi ;

The technology isn't dead either .The larger luxury floating homes . Can't call these houseboats !  Well these are built on a concrete hull that allows you a full basement even with windows at waterline level or just above or below that precious line . How do I know , well I was living on a converted coast guard boat and one was built right down the levee from me .     T.B.

I know right?  I never knew about these!  Interesting!

Like going to school; this forum!

Nine McCloskey class concrete ships were partially sunk as a breakwater at Kiptopeke Virginia to protect the ferry landing for the Chesapeake Bay ferry to Little Creek. The construction of the Chesapeake Bay bridge/tunnel eliminated the ferries but the breakwater is still there.

There's also one on Guam.  It was to be incorporated into Glass Breakwater in Apra Harbor but broke loose during the sinking and is intact and perpendicular to the breakwater.  It was a GREAT wreck of novice wreck divers and had an air filled compartment a couple of decks down.  WELL familiar with the Aptos wreck, too!
