I'm in the process of investing in a boom vang. I kept a traditional boom vang from my previous boat and would have to invest in the mast and boom bails in order to complete the installation. When you look at the cost of the bails and ss mounting bolts you're almost half way to the price of some rigid vangs. Initially the rigid vangs are higher but they come with all the mounting hardware. I'm a weekend Neuse River sailor and don't know if the additional cost of the rigid vs the traditional is worth the price. What are the advantages of one over the other?Thanks,tarheel
