Wannahobie, can you tell me more about your ratchet block selection? Looks like the upper section is mean for 6:1 purchase?
Yes, you are correct, it is a Harken triple carbo ratchet. I purchased it on ebay for $15 NIB.
It is basically a Harken 2613 which I modified. I removed the cleat system, and carefully drilled out the rivets and moved the ratchet sheave to an outboard position from the center. This allows this block to function as a double, leaving the ratchet functional. It also puts the control switch for the ratchet itself accessible. Odly enough, the stock position makes the ratchet active all the time with no way to turn it off. Reassembly turned out to be a real challenge. All those derlin balls seemed to make it impossible to get back together. I actually used maple syrup to keep the balls in their races (grease is not recommended on these). Makes a sweet block assembly now
. Anyway, I used long ss #6 screws in place of the rivets and put put it together eventually. However, I would not recommend this mod to a 2316, unless you can pick it up a real cheap, and have LOTS of patience. Do yourself a favor, and just buy the HSB411 special ratchet block from catsailor dot com. I think they sell it for ~$95
I once had an Alort Force 5 and then a Zuma once, both had ratchets, and I loved them (the ratchets that is). So I did a search for such a system for the Wave. I found this:http://www.harken.com/blocks/hobiewave.php
Anyway, it works great as it is. The middle sheave remains unused, as does the becket. But neither affects the operation.
I now use the old upper fiddle as part of my solo mast raising system.
