Interesting!

On the earlier 637`s we blew MBTs after we had stopped rising vertically... which always was immediately.

Would use as little HP air as possible, and as soon as head valve or upper hatch was open we'd use the LP  Blower.  Always wanted to keep HP Air Flasks charged, and did not want the noise from the compressors.

Again, this frequently was thru ice much thicker than a later imposed restriction.

This was after airless surfacing becoming routine. It is the same as using MBT except it takes a bit longer. Get the water out of the MBTs and the boat comes up more and is stable on the surface.

One surface the ice was across the top of the sail. The XO attempted to raise #1 and wondered why it wouldn't go up more than a couple of inches. He was looking down the well to see if he could figure out why; and I did to, until dawn broke over Marblehead(s) and we realized what the cause was.Big smile

Agree.

Airless surfacing (with LP Blower) would not cut it with the thicker ice we surfaced thru before the later restriction.  The head valve sometimes was much, much deeper when we Vertical Surfaced.
