I`m used to move my old H14 on top of my car (decontructed) And would do so with my H17.
The H17 has some more lenght en weight but with a third roofbar it would stay in the max load on the roof as much weight would be transferred on the rear bar that rests on the towing hook.
Rest me with only a mast with 8,5 meters.. My H14 has a 2 piece mast, and there are H16 with 2 piece mast also the wave has a standard 2 piece mast.
So I want to cut the mast in two (diagonal like the H14) and insert a aluminium profile witch glued a rivitted on one side. Would this be a constructive problem ?
Most forces go straight down..
