Zero buoyancy

I wish to dedicate this thread to Sailingdog. I cannot imagine him dodging this bait (and we might agree this time)

This craft, Mirabaud LX 2009, has been on its first test sail. Based on an 18ft skiff, it is designed with no - zero - buoyancy in the hull.
Might it be eligible for our Blue Water Cruiser list?

So do you need to get a running start with it?

Just because something can be done, doesn't mean it should be done!!

Or is there clear plastic sheathing?

Did a quick search on it, and found a u-tube vid, apparently of the first test sail, pretty interesting. You really have to watch when it hits the brakes....

Big deal...it's a monohull that can sink...

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

I'd say that the tubular CF frame probably has enough internal buoyancy to keep the frame, rig, crew afloat while not sailing. In that sense; it is not zero buoyancy, if it were it would go to the bottom of whatever lake or bay they were sailing in when it stopped. Seems like a small planing hull would be a better choice since it would reduce friction while sailing in non-hydroplaning conditions. (A design like the Moth is more practical IMHO).

I have to agree with the "bottom of lake" scenario. In the article they claimed "zero buoyancy", but I guess they stretch the truth a little.
