Re: Reaching struts

I've seen this problem on the J30 I crew on. With the spinnaker pole close to the forestay, it's almost impossible to trim the pole back. I've often found myself putting my hand out as a human reaching strut to increase the angle on the guy. We're only doing short, around the buoys races, but I completely understand the problem and see the value of another pole to push the guy out.

Yeah they seem to be making a comeback on some of those beasts, but that is a bit beyond the typical club racer!

Re: Reaching struts

In all my years of racing I have never set foot on a boat that uses a reaching strut. With dedicated sheets and guys, the guys are always run through blocks on the toe rail at the widest part of the boat which keeps the guys clear of the shrouds. Sometimes they chaffe a bit on the lifelines but never enough to be a concern. On boats that use sheets only, tweakers in the same max beam position for the guy side serves the same purpose. It is much easier to pull on a tweaker with every gybe than to screw around with a strut!

Re: Reaching struts

One thing you might want to look into.. the strut is usually 'lashed' to the shrouds to prevent it swinging aft (or forward, depending how it's aligning with the shrouds) under load.. a clew-strap style velcro strap might do the trick, much quicker to install and remove than a rope or webbing lashing.

That's what we did this year, with the block positioned at the boat's widest point. But the angle still wasn't very good. In the illustration, if the spin pole is farther forward, the angle is very tight, even with a mid-ship block so a strut is needed. I'm hoping to use the strut to get the guy further out to increase the angle.

From what I read of the 3 recent posts, a strut is still the way to go if the boat is older (as is ours) and a mid-ship block still isn't cutting it. Thanks for the confirmation, guys.

Re: Reaching struts



The merit of the reaching strut is that it increases the angle between the center axis of the spinnaker pole and the center-line of the after-guy in the same manner that a spreader does for a cap shroud on a mast. This reduces the tension needed in the guy and the induced compression load in the pole from the guy. On some of the wide-butt lead haulers of today ("sleds"), where the lead-block for the guy is already quite far off the center line of the yacht, a reaching strut might not be necessary but in older yachts, and particularly those with IOR induced lines, the reaching strut is a necessary element of the rig. The good news is that they are relatively short, accordingly light weight, and relatively easily positioned.

Re: Reaching struts

The guy lead block should be forward when reaching tight and the pole near the forestay.

With end-for-end twingers do a good job of that, obviously you don't want to be moving the block on every gybe.

With dip pole, and double sheets/guys the guys can be lead through a forward/midships block at all times. This also helps take some of the load off the foreguy as the pull is more downward.

Reaching struts seem to be fading.. definitely not worth the hassle of setting/removing for every gybe, or going through the hassle for a 30 minute leg. If should be long enough to extend beyond the shrouds from it's attachment point. I think and on-deck attachment point would not be 'in line' with the normal position of the guy. It's more of a chafe protection measure than a 'angle of effort' measure as the difference is only a few inches anyhow. A forward or twinged guy lead from the widest foward point usually avoids the grinding on the shrouds - though loads on the lifelines and stanchions can become a concern.

Last year, we led the guy to a block amidships on the rail and the angle was better but not great. While a reaching strut is the obvious answer, what do you guys do?

2. I picked up a relatively short strut at Bacon's that I think will work. The traditional attachment point is on the mast, but I think that I recall seeing a photo of the strut attached to the point on the deck. Ideas? I was planning to attach it to a sliding eye fixed at the forward end of our inboard genoa track and then lashing the middle of the strut to a stanchion to keep it from riding up.
