Vaka bottom: first coat of graphite
Two hours of work today. We bought a new roll of masking tape so we could finish to cover the hull with a plastic skirt. We then gave a light scuff with 240 grit to the hull bottom, and finally gave a first coat using about 250 grams of clear resin to which we added 30% (in volume) of graphite powder.
Here's yours truly giving the first coat
and here's Cinzia doing a thorough quality check:

Preparing the vaka for graphite coating
Just one hour of work today
Unexpectedly, we ran immediately out of masking tape 😧 so we will have to buy some more...
So, we decided to bore 4 holes in the carts and put one bolt in each through the aka support blocks to avoid that the vaka slides over the cart while moving the hull around.

Turning the vaka for painting
After much thinking, we decided to coat the vaka bottom with graphite. We ordered a liter of graphite powder but it we have not yet received it. Today, we turned the vaka hull upside down in preparation for the bottom coating. We succeded in the operation with relative ease notwithstanding the almost 200 kg. Here it is lying on a side
and here it is, resting on two 2-cm thick particle board panels on wheels.

Attaching the OB motor support
Two hours of work today. As anticipated, we prepared 150 grams of epoxy resin.
We then added microfibers and colloidal silica to prepare a glue and make the fillets. Here's the beam crossing the vaka hull under the aft deck
and here is where it comes out of the hull, with a milestone beer
