At the typical speeds a PSUB travels at, protrusion drag is very small. There are other issues you should focus on.

Ron. Keep adding your 2 cents. I was thinking of a way to add inflating ballast to give more freeboard when at the surface. Maybe hidden behind a retractable fairing to minimize drag when submerged.
