Concrete is an ideal material for what we want to do. I've included a link to a website dealing with how to make concrete submarines cheap, yes they actually work and are amazingly fuel efficient. concretesubmarine.com/ |

I have a buddy who was sub crew for quite a few years that might be interested if we got one.

Range data:
When you plan an engine for a submarine yacht you should forget anything that is recommended for surface yachts and come back to the basics. Fortunately there exists a fine model made by mother nature that has about the size of a submarine yacht and travels long distance as a submarine yacht is supposed to do - Whales! A streamlined body such as a whale can travel over long distances with incredibly low energy use. Studies suggest that a whale uses 5 times less energy for swimming under surface than swimming on surface where additional drag from wave resistance comes up. A graywhale of 18 tons displacement has 3000 kg (14 kg of fuel/day) to travel 20.000km (95km/day) in this journey he has about 589g/hour of fuel available for life support and locomotion. To simulate the locomotion model of gray whale a submarine yacht of the size of my prototype (20tons) is well equipped with a diesel of 1-3 horsepower. This fits well with my own field data that suggest that a small electric engine of just 200W can move a submarine yacht hull of 20 tons under all weather conditions. Such a submarine yacht is able to go 95km per day with 14kg fuel use per day - the problem is you might not find a diesel small enough for this.

We can get a 3HP diesel motor no problem they use them on some generators and I'm sure they sell them as motors on their own. The only issue would be laboor we'd need to group up somewhere near the water to work on it and cast it, It'd take what 8-16 months to finish? |

I have a spare 4 cylinder Isuzu 4FB1 diesel and a Hurth gear available, so there's about 40 +/- horsepower, I wonder how much of a submarine yacht that would power.... |

No idea, if we want more power I could give up the motor out of my SUV when the time comes, V8 with 300HP and 330ftlb of torque. It runs on gas but at low RPM it won't matter much unless we find somewhere willing to sell fuel cheap in bulk to us. |

You don't use gasoline in a boat if at all possible. also I want to make clear that the intended function of the submarine yacht is not to submerge really at all, and would have ample deck space and glass windows. My engine would be mostly used for electricity and climate control, actually propulsion ideally by electric motor. Also, where do you put you V-8's radiator? The engine must be converted to marine use, another story.... |

A sub wouldn't work well anyway for that application as far as I can guess it would be top heavy and want to roll in rough waters unless it was wide enough at which point we might as well have made a boat.I do have a question though, I've never really looked into marine motors so why do you avoid gasoline? |

Why avoid gasoline? KABOOM! Sheesh! Anyhow read the entire website...it's very informative. Also my engine is commonly used in marine conversions everywhere internationally. I'm trying to help here.... |

Oh right I never really thought about the part of a confined space full of gas fumes and it's helpful I just have never designed a ship before so I'd trust someone else to it and I'll read it all it's always good to learn something. |

Yes it is. Anyhow I'm going to calculate out how much imaterials will cost to build a 250' submarine yacht hull. I have a few ideas as to construction methods and such. Using recycled styrofoam and plastic, etc we'd end up with a cheap, efficient and permanent, i.e. unsinkable, mobile floating structure. You probably want individual "studio apartment" type cabins with hot and cold running water etc... |

Wait, why do we need a submarine?

Wait, why do we need a submarine? Because I say so. Do you know what the penalty for mutiny is? No read the entire website at the top of the page. |

Foam core. Cannot sink unless you want it too. |
