hi wouter, can you post the pic here, you mentioned. geocity as well as the whole f16 site is not accessible from china (like some other american websites).

regarding margin, yes I also believe solosailors should really feel safe with this very stiff superwingmast. but the best margin is still to have a look on it. looking from the mastbase to the top significantly shows the deformation the mast has to deal with. I never [knocking on wood] in 12 years spi-sailing broke a mast but damaged once a mystere 6.0XL mast when the spihalyard camcleat failed and let the 25m² spi suddenly completly slip in a gust. thats why I empahsize on the understanding what dynamic forces can causes...
