The bow bulkhead's position was established by palpatory percussion and measurement from the beam bulkhead. Then I drilled holes safely forward of the bulkhead to establish it's exact location.
Then I drew a line and cut the float in halves. OUCH!

Starting to build up a new foam blank for the elongated plumb bow. Old and new, side by side
I've calculated the added volume from bow bulkhead to beam bulkhead to be approximately 26 litres. I have to look closer at the difference between the two foam caps, but the added length alone should give more than 10 litres.

The first F22SR ? :-)
Is the new bow your own design or from Ian? I've noticed that the coming production F22 is going to have different floats that for example you have built:

Ian told me roughly what changes he had done to the production floats. I'm designing my mods with that as a back curtain. I'm still not sure whether I will do anything to the sterns, although tempting, as I want to keep the balance right and I think that will also contribute to a bit better longitudinal stability.
