I just got hold of a Marstrom carbon mast, only problem is that it is in two parts. I should be able to join the pieces where the spreaders will be. Profile is 210X 90mm.
As seen here the bottom is fine. The ball socket is also there, I just remove it for further reinforcement.
Forestay attachment is ok but the spinnaker is too low. Don't know if the u -bolt are for 2:1 hailyards. Anyone??
