LOL, meters,whats that??? Well the the safe place for the spin. hound is believed to be one third up,the distance between the main hound and top of the mast. I'm not sure where the stock spin. hound is on a N boat. Most seem to be half way. What boat did the spin. come from. Can you go back to that boat and measure those dimensions? I would opt for the lower spin. hound postion and if needed have the spin. recut.
