I need to purchase an oxygen system for an ASW27 (licensed in the Standard Category if that matters). Of course I will probably go with a Mountain High system so my main question is about the tank and the plumbing. My last system on my last ship used a huge steel bottle that was so big it would last a season or two. I see no reason to go with such a large tank again and when talking to the US suppliers there has been some discrepancy as to what size tank fits a 27. Also, is there any advantage to a composite bottle?
Thanks
