I went with a submersible large watercraft instead. Looks like a house boat, with an incendiary charge on the rear deck. At one point the bad guys came after me, they shot us up, I set off the charge and "sank" from the damage the dealt, really just submerging and disappearing off the grid for a bit. While radar and such are quite common, there is very little submarine surveillance, and I managed to keep us on the down low while we plotted our revenge against the fellow who tried to kill us.
