Shock Treat Your Holding Tanks Mid Season Too

Shock Treat

July 2, 2020

Alex Milne and Associates originally developed Head-O-Matic Shock Treat to allow airlines to help clean inside waste holding tanks when they bounce an aircraft on landing, thus helping to prevent odours in cabins.  Today it is used in recreational boats across Canada.

While is it a well known good practice to “Shock Treat” your holding tank on one of the last trips of the season, did you know that it is also worthwhile to do the same treatment mid-season too? Many boaters use it to clean waste tanks whenever tanks or hoses get skunky.  Simply pour one 900ml bottle of Shock Treat into the head, flush, and allow this to slosh about, in the holding tank, to deodarize and whistle clean walls, ceilings, lines and most importantly, holding tank sensors.  Shock Treat is eco-rated.

Shock Treat is available at most marinas and marine chandleries.  For more information visit

They have all been exceptional yachts, but this is the one I would most want to own myself. It’s a personal choice and a matter of taste as to whether you would prefer to have a sedan express model or a flybridge but in my opinion, the flybridge layout offers some wonderful attributes.

We met with Neptunus Managing Director Jan Willem De Jong this past fall to take the new Neptunus 650F out in Lake Ontario.

The Other Virgin Islands

Sunset off St John

By Mark Stevens

I was first seduced by the United States Virgin Islands during a ferry ride from St. Thomas to Tortola to begin one of our earliest British Virgin Islands charters nearly twenty years ago.

A perfect sunset off St. John with St. Thomas views for backdrop.

Clearing Pillsbury Sound, surrounded by voluptuous emerald mountains as the ferry sliced through royal blue waters, I was struck by the unspoiled ambiance of St. John, the island gliding past our starboard beam and the irresistible charm of a village called Cruz Bay visible from our quarter stern.
