We've been quite struggling recently with the fabrication of Protei_010 pouring today 10kg of concrete in our not very precise hull.
But we've learnt a lot.
And we got some clear idea of how to optimise the process ... This is great :
Blow moulding would save us assembly of the 2 half hulls steps - perfectly waterproof.
We could also manage the flexibility of the spine (thickness of the connection between hulls) more precisely.
And if we are going towards mass production (more expensive mould, but extremely fast and accurate manufacturing) :
Now can you explain why technical videos nearly always have bad music ?
