maintainance cost

The hull building cost for a submarine yacht as suggested and tested at ( concretesubmarine.com ) is already a lot more economic than building in other materials. But this becomes even more impressive when you compare long term maintainance cost. Other than a sail or motor yacht a submarine yacht is not planed to come out of the water every season. It is built to receive a similar amount of maintainance as other marine concrete structures like oilrigs and submarine tunnels do. In other words it is designed to stay in water for decades with no mayor maintainance. When we tested our concrete submarine yacht prototype we found that this unique quality pushes general operation cost of the yacht well below the operation cost of a similar sized surface yacht.

submarine yacht hull building cost

The building cost of a submarine yacht hull as suggested at ( www.concretesubmarine.com ) is about 1/3 of the cost a similar sized hull for a surface yacht would be.

The figure becomes more impressive when you look at the wall thickness. The wall thickness for a surface yacht of the size of our prototype (9 x 2,5m ) would be a few millimeters.

Creating a hull of 18cm wall thickness as our prototype had would be almost impossible as the only way to create thick walled curved forms in steel is hammering a red hot steel block at prohibitive cost. (See the making of TRIESTE).

In concrete you can do such forms in your garage.

submarine yacht cost

A submarine yacht is basicly a boat with a hull that can submerge and a tank for buoyancy control. Anything else is a can have - not a must have. The idea that a sub is a vehicle "full of high tech sistems" comes from military field - for a private yacht you should step away from that.
