Hello All,
I noticed that a few of my postings were getting kicked back by the mailing list server, so the below post of mine is a couple days old. I had to remove some of the olders postings on this thread to get it to come in under the server limits. I hadn't had trouble like that before so I didn't look for it. For a few days last week most every message I sent was getting through ok, but I was receiving a notice shortly after I sent each posting that the email was undeliverable. It seems to of worked it self out now.
Happy Holidays to all the SMMOs out there,
Brent Hartwig

You make a good point, however I would still find it important to have O2 and scrubbing back-up systems for emergency use, as well as redundant O2 and CO2 sensors and alarms . I find that for what ever reason I can sense if the air in a space has a lack of O2 and/or to much CO2. I sleep in a good size room measuring 15' X 25' by 8' high and if I have the door closed to the rest of the house and the forced air system off, I will wake up in the early morning with a desire to get good air. I wake up even sooner if I have my large dog sleeping in the same room.
I really enjoyed your page on whales and propulsion, thank you for putting that together. I would worry about having only a small diesel or electric drive system. Only since in my personal experience, if you don't have enough propulsion to to deal with some fast currents, tides, other boats, and/or a good backup propulsion system, you could very quickly find yourself on the rocks, above or below the surface. Allot of sailboat type clients don't mind a slower trip, but the motor yacht people love there power. So keep that in mind. As usual the sub would be tailored to the clients specs.
