And so let's see if I have correctly understood: it is extension with EXTERNAL linking tube, that means totally different system compared to the internal Nautix one tha can be seen here (and pheraphs only in photo...):http://www.nautix.com/Nautix/Nautix....ment&Langue=En
It seems not impossible to build! I've already made a splitboard snowboard for my girl so should be not a long work. If Nautix keep on ignoring my request I'm gonna make it by myself
What lenght of external linking tube you suggest? Fiberspar old booklets tells: " must allow a 4 inch (10 cm) ovelap inside OR OUTSIDE the top of the mast" Sounds good?
What's the best lenght in your experience?
And in the opposite, is it the Severne extension you talked about still available? Obviously not at an NP or NS style price...
