New to me rigging question

[Quiggers73]

Hi,

New to the daysailer and sailing.

I have looked in the book provided by Roger and am having trouble identifying these components.

Anyone help identify..

1. Set of blocks that were in the cuddy.

2. Blocks on the end of the boom and a shackle..

Thanks

At the end of the boom, part of the rigging is for the end-boom sheeted mainsheet. There may be some other blocks that are used for reefing and or outhaul.

Here's a picture of the end of my boom:


Remember, you'll find many small differences in rigging as the class rules do not enforce a standard. If you get the same result with a slightly different configuration, that's OK.

The second item is the poor man's version of a boom vang originally shipped with the DS.

Here's a discussion of a better boom vang. And some pictures:



Here's a discussion of the interaction of [urlhttps://forum.daysailer.org/forum/viewtopic.php?f=12&t=6834]Traveler and Vang[/url]. It shows a clear picture of end-boom sheeting with traveler.

Thats very helpful, thank you..

I see a lot of picks of travellers, but I don't see anywhere on the back that would attach.

Today is yard sailing day, I may post another pic or two.

My DS1 has stand-up blocks on the rear deck. I couldn't find a really good picture.



But on a DSII you may find simply an eye fixed in the corner of the stern on both sides.

The blocks allow for a traveler that is a loop, which means the apex of the triangle can move off center. With the eyes, you get a "fixed" traveler, meaning the apex is in a fixed position, or, if the pull of the sheet comes too far from one side (such as during a reach) one of the lines would go slack and then the apex can drop, but will not move very far off center.

Mine is the one that can in principle be adjusted for downwind, but I fix it in the standard position and forget about it.

I've owned a different boat, where the two sides come together in the middle of the deck in a way that allows them to be tensioned. This would make the height of the traveler adjustable. I never got the hang of it, before I sold that boat.

I have a more powerful vang which I use even upwind, and which takes over some of the functions of a traveler. So if I had to install one from scratch, I'd start with the simplest one, which is a fixed line, with the block for the main sheet tied at a fixed point in the middle.

If you like using a traveler, you just need two points in the back that you can tie a line across, that, if pulled comes to a triangle with an apex approximately 18" to 22" from the transom. It shouldn't be so high that you run your sheet "chock a block" at the rear when fully close hauled. If that happens, shorten the traveler a bit.

You use your favorite knot, perhaps an alpine butterfly, to proved a fixed loop for the block to attach to. (Single block). At the end of the book, on that metal strap, you put another single block, but that one with a becket (to which you will tie the end of the mainsheet).

In this setup, there's only a single block at the middle of the boom (on my boat I use a ratchet block there to make holding the mainsheet easier -- I like the Ronstan Orbit 55 for that). And then you have one swivel block with cleat on your center board trunk.

Some people prefer mid-boom sheeting, but then you need a multi-part purchase between centerboard trunk and boom.

I dont have any attachment points for a traveller.

Just the mainsheet block, although in reading Roger's book, I can picture the benefit of the traveller in keeping the boom and therefore the sail square.

It seems every picture of every block is different with different line configuration.

I know once I get the right configuration I can replicate it everytime.

But its the first setup I need lol.

I tried dried sailing today in the yard to see if three dimensionally I could get it to make sense.

I got the boom vang on as it was already run. The outhaul and mainstream will need some more research.

Do you have a multipart mainsheet for center-boom sheeting?

It would have a double, triple or fiddle block that fits an attachment at the middle of the boom, and it would have more than just a single turning block on the swivel for the centerboard trunk. Usually also fiddle, double, or triple.

If that's what you have, you'd rig that. It would be perfectly serviceable. The boom is stiff enough so that you can pull it down whether you pull from the center, or also from the end. (The one small difference is that the traveler changes the ratio between downward and sideways pull, but if you beef up your vang so you can use it upwind, it will have a similar effect).

If you don't have those multi-sheave blocks, then you're not set up for rigging a center-boom mainsheet. At that point you either purchase the missing parts, or configure your boat for end-boom sheeting (requiring addition of the attachments for the traveler).

This is what a traveler might look like on a DSII.
