I need to replace my boom front end. After removing the old head, the straight round section available on the boom arms is about 90mm (and the diameter is 36mm but this is easier to check and adjust if needed).

Would be awesome if some owners of the following booms can measure the width of the following boom front ends to see if they might work:
a) Severne
b) Maui Sails
c) North iFront 2.0
d) others?
e) Streamlined - seems to require a 105mm section on the boom, hence will not work.

^^^ indeed.

Somebody will recognise the model and tell you what fits
