I am trying to piece together a mariner boom rig. Got the boat incomplete. The boat has a worn ratchet/dual pulley block at the foot of the centerboard for the boom. Not sure if this is a booom vang as I see boom vangs termed as diagonal block systems at the forward end of booms to masts. I need the system for pulling in the boom when tacking in beginner's terms. I went to Defender and it was busy, the counter guy ponted me to the direction of prepackaged boom vangs. I brought a Ronstan Boom Vang marked as $99.00. I got home to see I was charged $238.00, the package was misplaced on the shelf. Searching around, it looks like the price was correct for it but is this vang overkill? When expanded, it gives me a length of 90" eye to eye and has the line wedge at the lower block. Is this the right boom vang to use for my boat? I have aft traveler pulleys and a pulley at the end of the boom, do I need an aft traveler as well as system I brought? Also, for purpose of pulling down the boom at the mast, do I need the diagonal boom vang or can I just pull it down onto the cleat? I am not racing.
Thanks
