Looking for Advice on Sliding Gooseneck

I just bought a Shark 24 and before now have never sailed anything larger than a 420 so a lot of the gear options on this new boat are new to me.

The Gooseneck on my boom is not locked to a specific location and can freely slide up and down the mast, I'm not clear on how it should be adjusted.

There is a cunningham for adjusting the Luff tension and that seems to make sense, but the outhaul runs from the clew through a pulley inside the boom and forward to the gooseneck where it comes out the bottom of the Boom and attaches to a 6 to 1 block and tackle.

Because the gooseneck is not fixed, when I tighten the outhaul it simply pulls down the boom until I run out of play in the tackle and the tension along the foot does not appear to change significantly.

Is this normal or am I missing a piece of the puzzle or doing something wrong?

If my explanation of the setup is not clear enough I will take a photo to show it better.

Re: Looking for Advice on Sliding Gooseneck

Usually with a sliding goose, the outhaul runs BACK to the outside of the boom. Somemtimes the outhaul has a 4:1 or 3:1 tackle inside the boom, before it exits... so that you tension the outhaul on the fly while sailing.

With the sliding goose, you can either use a standard cunningham (connected to a cringle above the tack), with the purchase of your choice (on a 24 footer, 3:1 or 4:1), or the cunningham can be connected to the bottom of the slider on the goose, and effectively do the same thing.

I don't think your rig for the outhaul should come out of the boom and go to the deck, it should connect back to the boom somewhere, the effective force should be to compress the boom into the mast (cause it's pulling the foot out away from the boom).

The outhaul rig will be similar to this (it's exposed to show how it works)...
My sliding goose (yes the boom is upside down, see the hole in the bottom of the slider, that's for pulling the goose down aka: cunningham, I use mine as a regular cunningham with a hook into a cringle in the sail):

Cleats on the boom for the outhaul (and flattening reef):

Re: Looking for Advice on Sliding Gooseneck

There are some good examples on the APS website that demonstrate various outhaul setups, also boom vangs and cunningham setups.

Re: Looking for Advice on Sliding Gooseneck

The sliding gooseneck is used to tension the luff of the sail. It is a system used when there is no winch for the main halyard tension.

The process of raising the sail on a boat with the sliding gooseneck is to loosen the downhaul, then raise the sail to the top of the mast with the main halyard. Sit on the boom (or otherwise apply tension to it) to tension the luff to your desired level. Now tighten the downhaul to lock the boom in place.

The Cunningham is used to flatten the main in multiple dimensions, not just to add luff tension. The downhaul only adds luff tension.

Once the boom is locked between the halyard and downhaul your outhaul shouldn't be able to pull it down that much. However on a sliding gooseneck system it would be somewhat more common to have the outhaul run to the boom instead of back to the cabin.

If you do have a main halyard winch you could do one of two things to make it operate like a fixed gooseneck. One is to tie off the downhaul permanently to a level that puts the top of the sail just below the masthead. Now you'll use the main halyard winch to control halyard tension. This is what we do on the Catalina 25 that I sail on (which also has a sliding gooseneck). The other option is to replace the gooseneck with a fixed one. If your mast and boom dimensions are the same as a Catalina 25 then you can get a pretty inexpensive fixed gooseneck from Catalina Direct.

Re: Looking for Advice on Sliding Gooseneck

That was a great concise explanation on how to use the halyard, cunningham, and outhaul. I always wondered what order to do things, that way makes perfect sense. Thanks!

Re: Looking for Advice on Sliding Gooseneck

Here are some Photos of my setup.

This shows the Outhaul Running from the Clew Into the boom


Here you can see where it comes out of the boom near the Goose neck.
The Larger blue Rope running to the left is the Boom Vang and the White Rope is the Cunningham


In these photos the sail is as far up as it will go (the head is touching the main halyard pulley)

There does not appear to be a place on the boom to attach a downhaul even if I had tackle for it.

Does what you see here make sense or do I have things rigged wrong?

Re: Looking for Advice on Sliding Gooseneck

hindsight I should have taken another photo with that outhaul righted to show it clearly
