I think Monte has the story straight but would add that they probably forgot to close one of those quaint little "vindows" downstairs resulting in one hull
full of water
, extreme list and the weight of the rig then taking the vessel right over.
I agree with 2Wind - I also own a Lagoon 440
and I believe that the only way she would float if full of water would be inverted such as the subject cat with a little air trapped in the fwd compartments.
What is Lagoon
thinking re "non-sinkable" when the fwd "watertight" compartments have a drain hole to the bilge
, a hatch
very low in the fwd bulkhead, a hatch in the deck
and a porthole on the inside of each hull. The supposedly "watertight" aft engine
compartments also have a hatch to the deck, a drain hole to the bilge
and various cable holes etc, somewhat sealed.
Frankly, there are NO watertight compartments in the true sense of the term in the Lagoon 440
and, if upright and full of water, hello Davy Jones.
My previous Schionning Wilderness had numerous, truly sealed, built-in floatation compartments under the soles of each hull, as do some other cats but I am not sure about other model Lagoons.
