Another unfinished boat found!

The other day i was digging through some stuff laying around the atic.
To find this:

A nearly finished hull, the fifth and final boat from the afterlife project.

This is the first f5g boat i designed completely by myself.
It is a lightair boat. 4years ago when designing it a prismatic coefficient of 0.42 seemed good for light air, the reason for such a low CP is that the front 8cm of waterline are concave! i tried to keep the boundary layer flow laminar as far back as possible.
The goal for the project was to test unariggs on f5g boats:



And to get good results at Koseze, the pond with no wind.

I never won a Koseze race with such a boat, but i learned a great deal about una-riggs!
more on that soon.


The above hull is identical to Blulife, the deck and layout are also very similar. The differene is that this hull has a badly alligned keelbox, so that will need fixing. Mast hole and rudder post are already in place.

At the moment it weighs 240g, once the deck is trimmed, masking tape removed and hooks are added i expect the hull to weigh less than 250g
This is a light hull considering it is all fiberglass.

The boat will be build with a 4500cm2 rigg, true to the blulife rigg, Fila spec. rudder and a bullb that will be shifted slightly further aft than on Blulife.

The boats name will be Life Afterlife.
