Joe,
Don't know if you remember, but I worked with you at the WRAM Show this year. Good show on your Type VII. I believe what Francois is talking about doesn't require a breathing tube or snorkel. He probably wants to evacuate the head space in the ballast tank and store it in an auxiliary tanks thus compressing the air in that auxiliary. When ready to surface, he would open a valve back into the ballast, and use the air pressure to force the water out. Should work fine providing he doesn't go too deep and the water pressure is greater than the air pressure in the auxiliary. Will I see you in Groton?
Frank
