Oday 10 puzzles.....help?

[Greg Luckett]

I picked up another little boat a few months ago and am finishing the few repairs it needed. A couple of the things still puzzling me are the way the boom is rigged for its sheets and the outhaul on the main.

On the bottom side of the boom are two blocks, one about midway and the other at the end. There is a block with a cam cleat on the aft end of the center board trunk which probably is for the main sheet from the mid boom block. There was a wire line run on the transom from port to starboard which may have had something to do with the block on the end of the boom. Any idea how this thing should be rigged?

The main is loose footed and looks like it just ties off on the end of the boom.

Thanks gang!

There was probably another block on the wire at the transome. The main sheet is secured to the end of the boom. It runs down to the block strung on the horse, up to the block on end of the boom, along the boom to the block at the midpoint of the boom. Then down to the block and cam cleat. Something like this....

[Greg Luckett]

Wow!!! That was unexpectantly quick and right on the mark......THANK YOU!!

I would not have figured this one out any time quick on my own.

My interior is different but the main sheet must be the same rigging. It make perfect sense now.

[Greg Luckett]

Is that a double block on that transom wire? I mean one block on the sheet attached to another block on the transom wire at a right angle to it?

Is that a halyard holding up the boom? I was thinking of using the main halyard for that when not being using on the main sail.

One last question. Is that another block for the main sail outhaul on the end of the boom?

Thanks!!!

Greg.

My old Sunfish had the same set-up: sheet clips directly to the bridle (no block), runs through two blocks along boom, and comes down to trunk. With a boat that small, do you really need more purchase?

Is that a double block on that transom wire? I mean one block on the sheet attached to another block on the transom wire at a right angle to it?

It can be but with a small boat its not required.

Greg- we used to use one of those bronze snap type hooks, the kind with the double opening claws, on the mainsheet of the Dolphins. They had an almost identical mainsheet set up. We also used that same kind of hook on Laura's Sunfish, which used a bridle across the stern like the 10 does. Just clip it in and go.

If you don't know which kind I mean I'll photo one later today and post the pic.

[Greg Luckett]

Thanks folks for the advice and explanations!

Charlie, I think I know the type of snap hook you are referring to. You pinch it and it opens like a spring clamp, right? I may even have some in the parts boxes.

I suppose the brindle is the wire going from port to starboard on the transom, correct? What does it do for the main sail?

Thanks again!

[Charlie Jones]

Greg- on a rig like that basically all it does is give you someplace to dead end the mainsheet and not interfere with the tiller. If you had some method of hauling the block on the wire bridle to weather, it could act as a crude traveler. On a boat that small that would be an unneseccsry complication.

[Greg Luckett]

Why not just terminate the main sheet where the block is at the middle of the boom, rather than running it to the end of the boom and to the brindle? I strongly suspect I am missing a key to understanding why this main sheet system is set up like this. Hmmm, maybe it acts like a boom vang too? Time for me to wrap up the repairs and painting on the boat and take it sailing. The weather this weekend looks good and I could take it out with the bigger boat on the lake.

Thanks for the help and advice!

[ChrisObee]

Its out on the end of the boom for leverage. If you used a more complicated tackle at the mid boom point that would work too.

[Charlie Jones]

gives you end of boom sheeting, and brings the sheet up front to you so it's more easily used. Little pressure on a boat that size so no multiplier needed
