A question about my mainsheet system (h16)

A question about my mainsheet system (h16) - 06/13/06 08:07 PM

Hello all! I just got an h16. I tried to setup yesterday and all went well untill I got to hooking up the mainsheet. I was using the assembly manual available online. It shows a configuration that is different from the one on my boat. My boat has two single pulleys on the boom, spaced about 6" apart. On the "lower" block there are two pulleys side-by-side and then a ratchet under that which attaches to the top of the traveler car. The diagram shows a small tab above the clam jaws where the sheet is tied before it starts it's path through the pulleys. My block does not have a place to tie here. This hardware is all labeled "seaway" Is this after market stuff? Can someone post an accurate diagram or photo of how to set this up? Thanks.

I think you have this [Linked Image]
which is a 5:1 system where you have two singles on top instead of a double. Changing that double to a triple would allow the line that is tied to the becket to return to the tab you refer to, for a 6:1 system.

Mine is a little different, I have a winch a the bottom that leads the line into the clam jaws.

here is a "diagram" of my setup. Sorry for the poor quality...

It is much the same. What can't be made out in the picture is that the bottom is a triple (the middle one is the ratchet). So the idea is the same, it is just that your ratchet block is in a slightly different place. I have altered your drawing (my skills are worse than yours)to give you an idea. The color changes are just to help keep track of crossing lines. The green bit ends up tied to the becket on the rear/upper block. You may have to try a couple different ways to minimize the sheet crossing itself and rubbing. This is high friction. If the block with the becket is in the front you may have a better option.
Does the double block on top of the ratchet swivel independantly? In the higher purchase sytems, the top set is oriented 90 degrees out from the lower set. Do the top blocks swivel? If so you could run the lines slightly differently. Or use a twist shackle. Look at this websites online store for examples of how the 8:1's are reeved. [Linked Image]

I tried to edit your image. I don't know why your blocks have disappeared.

The Seaway stuff is pretty old. If you've got the sheckels you should upgrade to Harken blocks. There's another thread in the H16 forum that discusses the best combination of blocks.

If you are new to sailing, or just going to be a recreational sailor, keep the Seaway stuff as long as it is working OK. (I'm still using my Seaway blocks, but I have to admit I'm a bit of a stick-in-the-mud.) Once you are more experienced, the change to better equipment will be more appreciated. And your patience will allow you to wait for that steal of a deal.

Only thing I'm itching to replace right now are the jib sheet blocks. The old ones are an engineering failure. I also need to add an inspection port on the port hull because there is a soft spot right in from of the pylon. Thanks for all of your help everyone!

The 5 to 1 blocks with the 2 single blocks on the boom was the standard when I bought my boat in '85. You now have the right arrangement. Just one note, what you call a winch in your diagram is just another pulley with grooves. When the ratchet is turned on, that pulley can only rotate in one direction. To feed line out, the line must slip over the pulley and the grooves slow it down. It helps you hold the sheet when it isn't cleated. If the ratchet is off, the pulley turns freely in either direction. I use that position when I get out on the wire and want to be sure I can release the line quickly.
