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.

The guy should go through a block further forward.
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

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.

Re: Reaching struts

On big offshore boats they are still pretty common. When you start playing with articulating bowsprits they are the only way to control the pole end. Think a 70' boat with a 65' asymetric spinnaker pole.

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!

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

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.
