The review I read of it in Small Craft Advisor buttressed my own thoughts.....hey, you like the reviews that agree, eh?

I got it for "taking the edge off" as you suggest. I think it's 4k to 9k btu's. Tip over off switch, low oxygen sensor switch...always use in conjunction with a CO detector admonition.

It was 20 bucks off so I picked one up. See how it goes...
