I can almost guarantee you this accident - and the speculation surrounding it - has caused nearly all other whale-watching companies to review how they operate. That's not a bad thing.
And there is even more speculation from marine experts that will bear some fruit while the TSB investigates and confirms what we already suspect happened. Meanwhile we can increase safety in smaller vessels by heeding what some of the marine experts have described.
"We have to go back, step one, and look at what kind of stability requirements are needed for cruise vessels, touring vessels, to ensure this doesn't happen again," said UBC professor of marine engineering Jon Mikkelson.
Naval architects like Mikkelson are asking if the design of the MV Leviathan ll was the right one for the ocean conditions off Tofino, or if modifications to its structure contributed to Sunday's tragic accident.
"It's designed to be a rugged vessel on the coast, but in many ways it's not designed to have people standing up on an observation deck," said Mikkelson.
The Leviathan II was originally built by Vancouver-based RivTow Industries in 1981 as a tug boat, and was named the Crown Forest 72-112.
In 1996, it was converted into a whale-watching vessel and renamed. The major change to its design was a new deck added to the top of the vessel. It was also lengthened, according to Transport Canada.
Capt. Ivan Oxford, a nautical training instructor, says that kind of redesign raises concerns about stability.
"You run the risk of moving weight from lower down to higher up, as well as adding weight on the higher location," he said.
It's not the first time a refitted vessel has flipped in B.C. waters.
In 1997 the fishboat Pacific Charmer capsized near Nanaimo, killing two people. And in 2002, the Cap Rouge ll rolled near the mouth of the Fraser River, killing five people, including two children.
In both cases, investigators found modifications — including the addition of heavy equipment high up on deck — caused the vessels to flip.
The TSB's Marc-André Poisson has said the investigation into the Leviathan ll tragedy is expected to takes months.
