Veeeeeeeeeeeeery interesting Carsten. Now I remember were I saw those drawings. The one that was built, have you heard about any pictures or video clips of it? Most sub designs are very heavy and so I don't think it's not a common thing for people to think about putting hydrofoils on them.

They have a 425 horse power aluminum Corvette motor in it. For the depths that I want to go to, say 300 meters I'll have a separate pressure hull for the engine with the read head of that pressure hull being a hatch closed with a locking ring type system so I can get to all of the engine easily when out of the water. I would also have a smaller hatch on top of the motor pressure hull for some basic work on the engine on the water. I like the Cummins diesels that can use bio diesel fuels.

I don't want to get bogged down with so many expenses and complicated parts that it took me twenty years to get it done.

Getting the nose up like that will help when dealing with waves but I think the Earthrace boat is allot better technology for making a smooth ride on larger waves. The Earthrace boat how ever is very susceptible to hitting a log of the like on the waters surface at high speeds, and with that plumb bow it's going to do some damage. Of course hydrofoils don't do so swell when you hit a large log with them either. There must be some story's out there of hydrofoil boats hitting things with there hydrofoils down.

I've already got a bolt on catamara platform design in the works to mount to the K-250 for surface stability, wave protection when the hatch is open on the surface and walking space all covered in Rhino coat. This sub already sank once because a rogue wave got water in the open hatch when it was on the surface without anyone in it.

This will give us great insulation value, allot of extra strength in the hull, and a extra factor of safety if the main hull starts to fill with water. This does not mean I plan to take the sub deeper then 250 feet when occupied. Once the syntactic foam is cured I'm thinking of Rhino coating the whole interior in a light grey color for easy cleaning. Since we are replacing all the thru hulls any way, we can have the new stainless steel thru hulls come further into the hull so we can trawl the syntactic foam around them. Of course we will need to use a metal prep cleaner then a high quality zinc primer on the sandblased bare steel.
