Well I guess the upside is they are both the same company

Glad they all got off okay..
Must confess.. even though I'll deliver them they do make me nervous.. the creaks and slamming below can be horrendous in a rising sea (2m+) and I usually spend a stormy period wondering if I'm gonna come out the other side.. that's when I sit outside for a while.. in the relative peace and quiet of wind whistling through the rig and the noise of the sea..
But at the same time.. I do like them.. its sailing.. one puts up with the 5% terror for the 95% good times..

Must be a mistake from the news reporter... cats don't sink.

Properly designed/built ones certainly don't. To be fair to Lagoon, we don't know it sank, just they they pushed the button when they were taking on water. To be blunt however, I was roundly castigated for suggesting that the Lagoon I inspected to list for sale last year was concerning as its bulkheads were not glassed in. It appears my concerns may have been well placed as other reports have the bulkheads collapsing, still they are all alive and quite unharmed, so its a good news story in that sense.

Have to wonder. I keep reading stories like this where the water was coming in but it's entry point could not be determined.
Thinking sail drive. Baring that it's a through hull or failed hull seem. Having had a boat take on water it was not that hard finding the failure. Why are these boats sinking and there is no obvious place where the hull is breeched?

To clarify, if you read the story and I quote the skipper here.

"The abandoned 50-foot catamaran, which was insured, is most likely to have sunk, but could be partially afloat.

Mr Garner told The Courier-Mail it was “probable’’ that his vessel’s hull had been cracked due to the difficult conditions."

[sabray]

Ohh the hull cracked that clears it up. I read it as he says.
“The water was coming over the floorboards. We did our checks, but couldn’t detect where the leak was coming from".

Get that it may not have sunk. Guess that's good. We need more non inhabitable debris floating around. Yeah it might still be floating.

That's the worrying part, it could be still floating out there semi submerged!

[sabray]

The worrying part is the water seems to come in and no one can find the leak. Maybe I am confusing baffling and worried.

Neither Double Island Point nor Cape Moreton have seen anything over 25kts during the last 48hrs according to the BOM database. The stronger winds in fact were well south. The swell has been small. The combined swell and surface waves have been under 3.5m. 80NM NE of Brisbane puts them on the edge of the continental shelf east of Noosa Heads, but with a sea running shallow to deep. The current will have been north to south at 90 degrees to the sea. This does not at first read, appear to have the characteristics of boat breaking conditions. Failure of a seal rather than the hull itself might be more probable.

I recall the sinking/grounding of another L500 last year when the saildrive was wrenched by lines caught in the props. Discussion revolved around the inadequate seal of the bulkhead between the engine compartment and the central hull section.

I believe that arrangement on the L500 is similar to that in the 440. Each hull has two "watertight" sections. The bow collision compartment, forward of the forward berth, is well sealed but relies on a good topside hatch seal and closure of the stopcock that drains it to the bilge above the keel in the mid section which is not water tight. The bulk of the through hull fittings lie in this central section and it is here where the two bilge pumps sit, as well as the manual pump pickup. The engine compartment pretends to be watertight. It too has a drain to the central section like the forward collision section which can be isolated by a stop cock. The engine hatch sits well above water height, but the seal may not be truly water or air tight. Although the bulkhead between engine and the central compartment is glassed in, there is a small 3 inch hole about 2 foot above waterline that allows fire extinguisher access in the event of engine fire. This should be a sealed inspection port, but is simply a hole that could be plugged in the event of taking water from the stern if one thought about it at the time.

These stories make one nervous. They sailed across The Tasman Sea without issue (one of the world's "black spots") and come to grief in an area not know for mishap. Very glad all were safely returns to land and family.
