Time to let air enter the boat.

I spent a lot of time to think about the ventilation...hmm.
1. It has to enter.
2. It should be able to leave.
3. It should replace the air inside. Easy I tought...guess if I'm wrong.

Four holes with weldes pipes. One "blows" forward inside the forward cabin. Nbr two exit in the salong to the right.
Three blows at floor level in the toilet and four to the left in salong. That is if both inlets points forward. By turning the port side aft meaning normally sucking air from inside will bring air to be replaced in half of the boat - even if all hatches is closed.

The aft cabins will have one dorado each. With possibility to set in three positions, closed halv open and full open.

When sailing hatches could be open (dep of weather) but when leaving the boat OR in bad weather full ventilation is still possible with all hatches closed.

So there are more area that lets air inside then out, but with a smart controlled fan in the 4" (100mm) engineroom outlet it ought to be nice air inside.
I once read about a ferro boat who sunk where all six (?) dorado boxes where lost and the big holes let huge amount of water in...

So I attached two bars on each side of the airtubes to be able to tie something on if I ever lose the doradobox.
I welded feet onto the protecting thing and a matching plate on the deck. If - and it will - the protection is moving and "skaver" the paint off, only stainless metal get visible: no rust - i hope.
Strange looking...
Front view. High and dry but not in the way of inner foresail. Quite nice place to sit on the doradoboxes.
