Both the 2nd and 10th Flotillas operating out of Lorient used Type IX U-boats.
They also operated out of Bordeaux with the 12th Flotilla.

BoarSpear2061,
Here is the info I have on the Type IX boats most of the data comes from Gordon Williamson's book.

Type IXA
Length: 76.5m
Beam: 6.5m
Draft: 4.7m
Displacement: 1,032 tons surfaced 1,153 tons submerged
Speed 18.2 knots surfaced 7.7 knots submerged
Range: 8,100 nautical miles surfaced 65 nautical miles submerged
Propulsion: (2) MAN 2,200 bhp MWM diesels (2) ssw 500 bhp electric motors
Torpedoes: 4 bow tubes and 2 stern tubes. 22 torpedoes carried.
Crew: 48

Type IXB
A small increase in fuel capacity over the IXA and the deck gun was positioned a bit closer to the conning tower. There were 14 built.
Length: 76.5m
Beam: 6.8m
Draft: 4.7m
Displacement: 1,061 tons surfaced 1,178 tons submerged
Speed 18.2 knots surfaced 7.3 knots submerged
Range: 8,700 nautical miles surfaced 64 nautical miles submerged
Propulsion: (2) MAN 2,200 bhp MWM diesels (2) ssw 500 bhp electric motors
Torpedoes: 4 bow tubes and 2 stern tubes. 22 torpedoes carried.
Crew: 48

Type IXC
Increased fuel capacity over previous versions. 54 were built.
Length: 76.8m
Beam: 6.8m
Draft: 4.7m
Displacement: 1,120 tons surfaced 1,232 tons submerged
Speed 18.3 knots surfaced 7.3 knots submerged
Range: 11,000 nautical miles surfaced 63 nautical miles submerged
Propulsion: (2) MAN 2,200 bhp MWM diesels (2) ssw 500 bhp electric motors
Torpedoes: 4 bow tubes and 2 stern tubes. 22 torpedoes carried.
Crew: 48

Type IXC/40
A small increase in fuel capacity. 87 were built.
Length: 76.8m
Beam: 6.9m
Draft: 4.7m
Displacement: 1,144 tons surfaced 1,257 tons submerged
Speed 18.3 knots surfaced 7.3 knots submerged
Range: 11,400 nautical miles surfaced 63 nautical miles submerged
Propulsion: (2) MAN 2,200 bhp MWM diesels (2) ssw 500 bhp electric motors
Torpedoes: 4 bow tubes and 2 stern tubes. 22 torpedoes carried.
Crew: 48

Type IXD1
Only 2 built (U180 and U195). They changed the propulsion to 6 Daimler Benz MB501 (3 per shaft) to increase the boats speed...Turned out to be an unreliable technical nightmare. Ended up being reconverted to cargo carriers.

Type IXD2
A unique and successful Type IX. 28 were built. It had a longer hull that allowed a twin propulsion system. Two diesels propelled in on the surface while two supercharged diesels were used to quickly recharge the batteries.
Length: 87.6m
Beam: 7.5m
Draft: 5.4m
Displacement: 1,616 tons surfaced 1,804 tons submerged
Speed 19.2 knots surfaced 6.9 knots submerged
Range: 23,700 nautical miles surfaced 57 nautical miles submerged
Propulsion: (2) MAN 2,200 bhp MWM diesels (i think) and (2) supercharged cyclinder 2,200 bhp diesels(2) ssw 580 bhp electric motors
Torpedoes: 4 forward tubes and 2 stern tubes. 24 torpedoes carried.
Crew: 57

As far as dive time, It was a general estimate from a few of the books I have that the Type IX was around ten seconds slower in a crash dive then a Type VII. Of course that is just an estimated time...since factors such as sea state, speed, crew reaction time etc, could change the time one way or another.

Hope this helps.....

Here's a link to a design study the US Navy made after the war
