No, you don´t. Your blocks are high up in the mast with the Euro Halyard (Aussie Halyard). The last part runs through the fairlead and then down to the cleat. I still have the old ones at the mast, they do not bother me. If you need more let me know and I will see if I can get a picture once this storm is over. The no 58 boat shows the blocks on the top of the mast.
