Re: Large Catamaran Flips In Sydney

On another forum a member says that the cat was racing. We have had some strong and gusty westerlies/northerlies in the last week or two. Probably the mast has hit the bottom and she won't invert further. Maybe some flotation areas bow and stern are stopping the hull going under, or she blew into shallow water. The mast hitting the bottom has happened to two pod cats racing in Australia before.

The problem with cats, and I have owned multis for 35 years, is that when racing the boat will not make you reef. On a mono you go faster by keeping the boat flat and well balanced. I quickly learnt when racing my 31ft tri in the 80s that skill was important for speed but bravado was also vital in high wind races. Whereas a wipeout on a mono may entail a gybe broach and blown out kites, a multi just keeps on blasting and if someone else is beside you there is the temptation to keep pushing rather than backing off.

So multis require the crew to be vigilant, and not let the boat dictated when to reef etc. Just like driving a car, you have to know when to back off rather than get made to by the boat heeling, broaching or slowing down. Great boats, just need to be sailed differently.

cheers

Phil

Re: Large Catamaran Flips In Sydney

Looks to me as though she is resting on her mast, that is touching the bottom. Used to happen when flipping a Hobie 18 in shallow water many moons ago.

+1, I had my old Hobir 16 like that once or twice (it was a PO who put the bend in the mast though)

Re: Large Catamaran Flips In Sydney

A Marine Rescue NSW spokesman said, about 3.20pm, Marine Rescue Solander radio base overheard a report of a vessel overturned in the mouth of Port Hacking, east of Bundeena.“The rescue vessel Port Hacking 30, already in the area on training, reached the capsized catamaran within six minutes,” he said.

“The vessel is about 40 feet long.
“The crew members are safe.
“Marine Area Command was notified and a water police crew was sent to the scene to take control.
“Wind gusts at the time of the incident were recorded at close to 35 knots.
“When the water police arrived the wind had decreased to around 15 knots.
“The overturned ‘cat’ has been secured off Jibbon Beach close to a cruiser that ran aground Sunday.”

Re: Large Catamaran Flips In Sydney

I sure could be wrong, but the first pic seems to have the cat much further out. Unless it's further east and up on the reef in the corner, or west, there is a long sandbank. Also, there's a racing mark nearby. Who's got their plotter warmed up? I'm not onboard today.

How could it be done deliberately?
Not to flip it, but to balance it as shown.
Easy - do it in shallow water. Mast rests on the bottom, sometimes known as a choc top as the tip of the mast comes up brown. Looking at it she will sail again with out too much effort

But at least it is leaning quite a bit less than 90 degrees rather than the cat's 90-plus. And the cat is partially sunk while the mono is resting on its bottom hull as in a grounding.

Glad to hear that you didn't fall over out there. You or your vessel would not have been so easily retrieved from a flip off Sydney Heads.
