Exactly - so the advice and teaching ought to be that in a safe situation you turtle your boat (with a rescue craft standing by with a line to the mast head, if you're worried), and you find out where the air pocket is, and how big it is.

But even then I think the lack of an air pocket is overstated.  I know the Bug has pretty much none.  I think the very shallow cockpitted 4000 is another.  What else?  Of course double floors have reduced side tanks which reduces the working bouyancy when inverted, but even then there is usually plenty up near the mast.  But boats are also lighter for the same volume which tends to counteract.

So can you name some Nessa - I'm inclined to put this down to the over-hyped risk that is associated with inversion.  Especially as I make a point of inverting just about everything I sail.  Never found a problem (ie no air pocket yet (other than the Bug).

It's an interesting point that those who advocate the removal of side tanks to make boats float lower are actually suggesting something that could worsen the consequences when there is an inversion.....and many inversions are kinetic energy driven, not due to resting instability.

doubt there'd be much under an MPS or moth.... but on 'normal' boats, I take your point.

Been under our Scorpion a few times after being dis-masted on a few occasions. Funny how much faster the boat inverts without a mast to slow it down.
Plenty of room, probably enough for two and with romantic lighting coming through the c/b slot as well. :-)

In my opinion the cockpit of an inverted dinghy is a dangerous place to be in anything other than a controlled environment.  Yes, you could do as you suggest and set up a completely unrealistic situation to explore how much space there might or might not be, but what would be the point?  If you have inverted your boat in anything other than flat calm conditions (and how on earth did you manage that?) then there's no way you should be thinking of gong under unless you are really really desperate.

The cockpit of an inverted boat is full of rope, wire, blocks etc all floating about and dangling down just waiting to wrap round your head, neck, arm, leg, whatever, and keep you there.  People don't drown because their boats invert,  they drown because they have become trapped underneath them and panicked.  At this point their BAs work against them and they are pretty much a lost cause unless someone can get the boat upright.

The biggest problem facing those with an inverted boat happens when they board falls into the case and they have nothing to lever it upright.  Common sense then says to avoid such an issue fit your boat with a device that keeps the board out of the case when sailing, there are plenty of different ways to achieve this and they can save an awful lot of stress as well as your life!
the same, but different...

How right you are about the board Nessa. Plenty of room under Tasar but best not to let the board float away first!

It used to be quite routine for me to duck under my Cherub into the air gap to get the kite down before righting it. Much easier than trying to get it down with the boat on her side. It was a strangely peaceful place with much less drama than was going on outside. The water isn't splashing about so much, less wave moment all the rest of it. I had generous tanks, no false floor and a very clean interior , what with no halyards (other than kite), minimal and well organised controls etc, so probably a best case situation.

I am with winging it on this.

We always teach that getting out from alongside the cockpit and to the stern but remaining attached to the boat somehow (holding the mainsheet if available) is the only way to do this until the boat it stabilised by someone getting to the board on on to the board.

That way the person in the water can then go and do thing like drop kites, chuck jib sheets over and the like.

There is no way I would ever advocate going under a turtled dinghy. Best to get it on it's side and stable ASAP.

Larks readily drop their metal centre boards back in the case when starting to go turtle.  Pretty easy to tie it off to stop that happening; if you remember.

I can remember ducking under a Firefly when I was a kid to get the board out. It was fine, but certainly not something I'd encourage small children to do.

Must check what a Feva is like underwater - can't believe there is a nice cosy place like the Firefly or Scorp.
