The main problem around hereis getting regular freedivers to do constant ballast with.
Support crew is no problem, as I stated before.
Boat is no problem, 28 person 30 ton steel slavage vessel with a lifting boom.
Bottom weight is no problem, lifting boom on the back of the boat.
Depth is no problem, I would only start out doing it at depths that I can already hit- 100'.
Building it is not going to be a problem, fully equipped shop with friends who actually know what their doing.
I just need some plans to work off of. I know others are doing the same thing out there. I just want to make a recreational one for fun- no teflon cable here!
