Today, 5 days after moving aboard, we slipped our lines and took Alanui to a local dock to pump out the holding tank. I want to mention a product that is absolutely amazing: CANNDURE, (493)291-1658, it's a holding tank deodorizer. A year ago when we bought the boat if you flushed the head you got a whiff of hell in the saloon. The vent for the holding tank is inside the Portuguese bridge, and if the light in the galley is open, the fumes make a b-line for it. It was enough to gag anyone. So, a buddy suggested we try Canndure and within 2 treatments the smell was gone, I don't mean less, I mean GONE. Well when we moved aboard we had another similar experience. We had neglected the boat for a few months, so the odor when flushing was ripe. Again, two treatments later, and it's all roses and sunshine! So, if you have a head odor issue, try Canndure. So today my wife says to me: I want to make sure we use the boat head every day so I can figure out how much Canndure to bring with us. I tried to explain that we would probably be pumping overboard just about every day, but she was insistent on getting a baseline for total number of days to fill the holding tank. A bottle of Canndure will do about 3 full treatments. So, we will go through this exercise, but I'd like to ask those of you cruising: 1. I assume at anchor you use your holding tank, out of respect and hospitality to your anchoring neighbors? 2. Once at sea, I assume you pump out asap, then throw the valve so all additional uses of the head discharge overboard? 3. Is there ever a time you modify your overboard habits that should be considered? I don't mean the obvious times when your in a sensitive marine area, but rather like when your fishing or some other activity? Finally, I don't have any interest in the Canndure product or company, other than being a very happy customer! Scott Bulger, Alanui, N40II, Seattle WA
