Arne:
How thick is that mast sole in your writeup?
It doesn't appear to be fibreglassed, only epoxied?
So, there's a gap underneath?
How heavy is Ingerborg's mast?
Mine is 90kg, just making sure that something similar to Ingeborg's mast sole will suit mine.
I'm thinking it might be simpler for me, while the boat is in the water, to sculpt a mast sole out of foam, then make up the plywood version back in the shed.
David:
That makes an annoying amount of sense.
Can one mitigate the heat problem by doing successive layers, say, 24hrs apart, 10mm at a time?
