No wonder he owns a motor sailer, there would never be enough wind to sail anywhere!

The problem with this arguement is we have no clear definition of what we really mean by unsinkability. The Titanic was unsinkable, according to her design requirements, just when she hit the iceberg it did more damage than her desing specs allowed for. Equally there will be a level of incident which will sink an ETAP or Sadler but we need to define what level of incident is acceptable. As for free surface, it is just as much a risk low down as it is high up. tankers use it's effect to maintain a reasonable metacentric height when in balast otherwise they would be too stiff, the the Free Rnterprise disaster was free surface water only just above the waterline. Floating upside down is not as good as floating the right wat up.

When I look at pictures of etaps on their website, sailing when fully flooded, I find it hard to believe that even putting hundreds of kilos of additional gear on board would cause them to sink if holed.
I also suggest that the "free surface effect" would be hard-pressed to capsize a yacht that has a ton of iron six feet beneath the water. As proven by the fact that the boats can sail when fully flooded.
Undoubtedly there will be some level of load that would prevent the reseve bouyancy from keeping the boat afloat. I find it hard to believe that a normal load of gear, even liveaboard cruising gear, would reach that limit, but that is just my gut instinct. Captainslarty seems to have a different gut instinct, but quite honestly his seems to be based on prejudice. I can truthfully say mine is not, because I do not now own, and never intend to own, an etap.
If his complaint is etap claims the boat to be unsinkable when clearly some level of load must cause it to sink, I think his complaint is misplaced. Some level of load will cause EVERY boat to sink, even if the hull's integrity hasn't been breached.
If his complaint is that a "normal" level of gear (or even his level of gear) would cause the boat to sink (despite the boat's claim to unsinkability) I think it is up to him to show us, even with some rough calculations, why his hypothesis is correct.
In any event, it seems to me that anyone who is sinking would be much happier being in an etap than in another brand of boat, or in a liferaft. If it turns out that the weight gear is a problem, THROW IT OVERBOARD. If the choice is between sending 1,000 pounds of anchors and chain to the bottom in the boat, or on their own (with the boat staying on the surface), it seems to be a pretty obvious choice, doesn't it?
