Actually it was just the slider in the boom which was a EASY fix. I have sailed many different set ups and find that the main really is not your power of the boat but it does help. The set up where the wind can spill through the bottom helps for speed and allows me to mold it into an efficient wing. You are flying on the water the same way a plane flies through the air. It is a wing. One you can adjust.
As far as sound that does not make sense what you are saying. It takes resistance to make a harmonic sound. The shrouds can do that but the mast is shaped differently and not an efficient harmonic tool.
But then again you did spent 130 hours experiencing what you did so you must be right. I still like my set up and it did great last night in the race. Sort of flew past a great majority.
If it doesn't move SHRED IT!
