Per Areopagus: yes. Raked wingtips are slightly more efficient than winglets, but for 737-sized aircraft move them from, I believe, Class 3 to Class 4 in terms of apron footprint (> more cost). But the Navy won't have to deal with that.
Quote: "BAMS would be particularly useful for India because it is optimised to operate in conjunction with the Boeing P-8A Poseidon, of which India has ordered eight examples designated as the P-8I Neptune."
.....and differs from the US version by having a 360 degree belly search radar, and a Magnetic Anomaly Detector at the tailend.

Although minor, the rake wingtip does not obstruct the view of the observer as much as the blended winglet. When differences in performances are small, these minor items can tilt you decision one way or the other.

It surprised me a little. I knew raked tips were more efficient at cruise, but I had the idea the P8 would be spending a lot of time at relatively low speed loiter. I guess getting to and from station is more of a factor. One of the things that makes the P-8 so much more useful than a P-3 in a world with fewer bases.

With all the sensors involved now-a-day, you can cover more area (because of curvature of the earth) if you are higher up.
Weapons like depth bombs and torpedoes will be evaluated for high altitude drops. Guess the only time when you want to drop down on the deck would be if you want to get an eye ball on something or drop a survival kit to someone in the water.

The P-8A/I also uses the B-737-900ER wing, as opposed to the B-737-800 wing, which holds less fuel. There are also hard points on the wings and a bomb bay aft of the wing that commerical B-737s don't have.
