Last weekend racing around the Coronados with my spin up in strong beam winds the spinnaker guy (the line going to the pole) was so very tight it broke the midship stanchion. There were previous small cracks along the base of the stanchion.

Both midship stanchions were replaced this week at considerable expense.

One could use a twinger on the line to pull it down. A twinger is a block that can be snapped open to put it on the middle of a line, then snapped closed. In this case, the guy runs through this block, which is then pulled down lower.

One could then pull the guy down to the rail, taking load off the stanchions, lifelines, and shrouds.

Question: has anyone done this on a C25, is there value? WM has the twinger block for about $30 but I question if I could get enough force on it to make it useful or where to fasten it on the rail. Obviously don't want to use stanchion bases.

I've sailed on big boats with these but never deployed them.

Waste of time and money on my little boat?

I use twings on my CP25 (almost always attached, occasionally employed), and there are times when they come in very handy, esp in strong winds.

However an overriding question in my mind in this case is how do you route your spin lines? I've never had a loaded spin sheet/guy load up a stanchion, life line or shroud. The headstay yes, if I allow the guy too far forward in heavy air. The only thing attached to the midship stanchion is a turning block at the base (low leverage), and even that is just to route the sheet/guy, the real spin load is being carried by another turning block on a track farther aft. Is this not how the C25 is rigged?

The spin pole was forward and just off the forestay. I can't afford spectra sheets, and my 1/4 inch stayset was stretching in the gusts. I had to winch the pole off the forestay. My spin blocks are way aft. The force of the guy (line to the pole) laying alongside the stanchion and lifelines broke the stanchion.

The force being applied laterally by the tight guy and the big gusts had to be seen to be believed.

We got the spin down soon after.

I cant afford Spectra sheets either! Know the feeling winching the guy off the headstay. Been there done that, but I dont recall there being a load on the stanchion at the time. Will have to check that out next time we go out.

So I take it the issue was the lateral load at the top, as opposed to the base. If you're not going to use the base for the twing, do you have an outside track (ie continuation of the spin block track)? Or do your aft spin blocks attach to the pushpit base?

Read my C-25 spin set up in the tech tips. We used Twings (might have called them tweakers in the story - same thing)

I recommend twings. For one thing, if there's that much wind, using a twing on the sheet as well as the guy helps control the spinnaker on a run and chokes it off a bit, depowering the chute. Be a snap to install with another set of genoa car leads on the rail track located somewhere around the chainplates.
