capability. the bluefin is a capable system but it just has a lot to cover. and there are not many systems out there that can do this job. >> so tim, your company purchased a bluefin-21, so you know quite a bit about this. what are the advantages and disadvantages of this technology? >> well, one of the primary advantages is the system is not connected to the ship. so if you're in really rough weather, the auv is close to the bottom. it is unaffected by the ship's motion riding over the big waves. so with the towed system, there is a direct connection to the tow fish, so as the ship travels over big waves that motion woud be transferred back to the tow fish, so the quality of the data should be very good. >> good, i hear you're agreeing with him sylvia?
