Robbe definatly has a good looking sub. The only problem with it is that it is a dynamic boat, which simply stated is that it always has positive bouancy and must be moving forward to create downforce on the dive planes to make it dive. It will not submerge statically (sitting still) I have seen them converted over to dive statically but it does create a lot of extra work and headaches. Someone that is looking to get into subs probably should steer away from this type of endeavour. If you add up the total costs of buying the sub and then purchasing the parts to convert it you probably will spend as much as if you just bought a static boat to begin with. On the other hand, Dumas makes a smaller sub that is also dynamically dived (dove???) and it is consideably cheaper. I do know this boat also has an inherit problem of the watertight compartment leaking. You have to be very dilligent when assembling the WTC. Unfortuatly, I do not believe there is such a thing as a beginners or trainer submarine, save for the little tub or aquarium toys you see on Ebay. They all require careful attention and good assembly skills to make operate.

Best of luck to you!!

There are two types of ships: submarines and targets
