Hyde Streamstay One Solid Rod Furling System

Introduction

The Hyde Streamstay One was the first modern furling system. Designed by Tim Stearn and introduced in 1971, it is still in use on thousands of yachts worldwide. The popularity of the Hyde system was largely due to the large charter boat operations, who embraced it early on for its bulletproof nature, easy maintenance attributes, and its unmatched reliability.

Occasional bearing replacement (on average about 8 years), and periodic inspection are all that is necessary to keep this system in top form indefinitely.

Although new systems are still being made, we frequently get calls from people who bought a used one or who found a system abandoned in a boatyard. Usually all these systems need is a bearing replacement kit or a shortening kit to put them back in use on a new yacht – which they will probably out-last as well.

Features

  • Solid Rod Design -- means less stretch, less windage and greater strength.
    • Forestay rod of 6061-T6 aluminum stretches far less than a wire headstay – less even than stainless steel rod rigging. Less stretch means less headstay sag and greater sail efficiency.
    • High Torsional strength of the rod is equivalent to hollow sectional systems many times larger in diameter. This smaller diameter is much more efficient aerodynamically – resulting in less windage and more efficient sail performance.
    • Solid rod is much stronger and more impact resistant than hollow systems. An impact from a spinnaker pole that would deform the luff grooves of a sectional system – making it impossible to raise or lower a sail – will not affect the rod. Even the travel-lift can't hurt it.
  • Round rod profile furls easier than any non-round section. "Rounds roll".
  • Stainless Steel Terminal Ends: Type 316 Stainless Steel rod end components are machined from solid bar for strength, reliability and a virtually permanent life span. End fittings are permanently attached to the rod, but are reusable in the event that a system needs to be shortened, or the rod replaced.
  • Drum, Drum Cover, & Halyard Swivel: Cast from high-strength, lightweight, Almag 35, these fittings are machined and hardcote anodized for long term corrosion resistance.
  • Low System Weight: This combination of innovative design engineering and careful selection of materials results in a furling system that weighs less than any sectional system available today. Less weight -- especially in the ends of the boat and aloft -- translates directly into increased boat performance.
  • Easy Maintenance: Occasional bearing replacement (on average about 8 years), and periodic inspection are all that is necessary to keep this system in top form indefinitely.
  • Unmatched, Proven Reliability: For almost 50 years the Hyde System has been in production, virtually unchanged from its original design. Thousands of boats all over the world are still sailing with their original Hyde system, many are entering their 4th or 5th decade of continuous service.

Bearing Replacement Kits

With a little easy maintenance and occasional Bearing Replacement, your Hyde System should last several lifetimes. Bearings are easily replaced by any individual who is mechanically inclined and has the ability to follow instructions. The system must be down in order to do any bearing replacement.
To access Bearings in the Lower end, remove the Drum Cover screws (#11) and pull off the Drum Cover (#8). Then remove the Drum screws (#10) and pull the Drum (#9) off the bottom of the System.
If you have difficulty removing the Drum or Drum Cover, it is due to corrosion between them and the SS Terminal End components. It is usually effective to spray the area with WD-40 or other penetrant, let it soak in, and then use a mallet (carefully) to knock the Drum (slowly) off the bottom of the System. Use a block of wood so as to not damage the Drum.
To take out Terminal End Bearings, remove set screws (#5), and unscrew Barrel Housings (#3 & #26) from Tapered Ends (#7).


Bearing Replacement Kits are available in three configurations:

Terminal Ends Bearing Replacement Kit Hyde # * -31
This kit has all materials needed to replace Bearings in both ends, including screws, Allen wrenches, special high-torque Locknuts, Bearings (and Bearing Spacers if required), ultra high-pressure bearing Grease, Loctite, Oil Seals, and instructions. No special tools are required.
Halyard Swivel Bearing Replacement Kit Hyde # * -32
This kit has all materials needed to replace Bearings in the Halyard Swivel, including (2) Bearings, snap ring, new screws, and high-pressure bearing grease. However you will need a large pair of snap ring pliers to complete this replacement. The system must be down in order to replace the Halyard Swivel bearings. All components except for the Halyard Swivel Core are removable over the Top End of the System.
Complete Bearing Replacement Kit Hyde # * -30
This kit has everything included in the two kits above.

Shortening Kits

Shortening Kits are used to reduce overall system length, when modifying the rig or transferring the system to another boat. It is the upper end that is usually shortened so as not to change the height of the sail feed entrance.


Shortening Kits Hyde # * -33
The standard Shortening Kit has all materials needed to shorten one end, including compression sleeve, dowel pin(s), drive lock pins, special epoxy, and instructions. Kits are also available with new Tapered Ends, See Hyde System Pricing Pages for details and options.
Special Dies and a Press (Nicopress Hydraulic Tool No. 635, or equivalent) are required to complete the shortening process. Your local rigger will most likely have a suitable Press, if a standard tool is not available a shop hydraulic press (min. 35 tons) can be used if properly set up. Appropriate Die sizes are listed on the Pricing pages. While both Dies and Presses are available for rent, keep in mind that shipping a Press (80 lbs.) is expensive, while shipping the Dies (3 lbs.) is easy. Hyde Die Sets are 2 1/4" wide x 1 5/16" thick x 2 5/8" high.

Replacement Halyard Swivel

Replacement Halyard Swivel Hyde # * -50A
Long term monitoring of thousands of systems in the field shows that the only drawback to the original Hyde system design is the fact that the Halyard Swivel Core is not removable once the system is assembled. For those rare occasions when the Halyard Swivel Core is damaged and requires replacement, a new Stearns style Halyard Swivel is available which "splits" to fit on existing rod without end replacement. The new Stearns style Halyard Swivel features longer, positive locking delrin insert bushings that are longer and much more substantial than the original Hyde ones, and are easily replaceable.

Wire/Rope Furling Line
To keep drum sizes to a minimum, Hyde Systems are optimized for use with wire/rope furling lines. Tail-spliced, like a halyard, these furling lines come with stop & oval sleeves for attachment to the drum with a nicopress tool. Trim the wire length to the distance from the cockpit to the Furling Drum, making sure the wire is short enough that it doesn't come into your hands in your normal furling position. Overall length, after trimming, should be approximately twice the boat length for large genoas in average installations.

Troubleshooting

The standard considerations in all furling system installations are:


Halyard angle -- angle should be aft of parallel to the luff when the sail is fully hoisted. On many masthead arrangements this will require a halyard pullback device installed on the mast. (See Accessories)

Halyard Swivel Height -- Halyard Swivel should be within 12" of the halyard sheave when the sail is fully hoisted. On shorter sails, this will require a wire pennant attached to the sail at the top (for performance), or at the bottom (for visibility). To check Halyard Swivel height, or to measure for a pennant, carefully hoist the Halyard Swivel with the sail attached to it, but not attached at the tack. When sail is fully hoisted measure from the tack of the sail to the tack pin, or shackle, on the furling drum. Pennant should be 6–12" shorter than this measurement and preferably, attached directly to the sail.

Furling line angle -- furling line should enter the drum at 90 degrees to the luff. This is achieved by adjusting the position of the furling line block or fairlead closest to the furling drum.

Furling line tension -- Furling line should always be under tension when the sail is being unfurled. Leading the line through a ratchet block mounted aft of the operator is usually a big help.

Furling line jam -- there should not be so much line on the drum that it binds against the drum cover when fully wound for any particular sail. Start with the sail rolled up. There should not be more than 3 wraps on the drum when the sail is tightly furled with the sheets wrapped around it twice. If you cannot get enough line on the drum to completely unfurl the sail, then the line you are using is too large. Reduce line size or, remove the core in the forward third of a braided line. "Coring" the line will reduce the amount of space it takes up and cause it to lie flatter on the drum. This should be done in all furling installations using standard braided line, as it reduces fouling and overrides while still giving you a full diameter line in the cockpit. Some systems, notably Hyde and Stearns, are best suited for wire/rope furling lines in many applications. (See Accessories)

If you are experiencing trouble with your Hyde System that is not related to any of those items above, it is usually one of the following problems:


System doesn't rotate smoothly – With reduced backstay tension and no tension on the furling line, grab the drum and rotate the system by hand. If it feels rough or bumpy it is time to replace the Terminal End Bearings, Torque Nuts, and Oil Seals (See Bearing Replacement Kits).

Hard to furl – If you've already checked the Terminal Ends (above) then it's time to check the Halyard Swivel. Lower the sail and rotate the top of the Halyard Swivel while holding the bottom. It should rotate smoothly and easily. If not, you need to replace the Halyard Swivel Bearings. (See Bearing Replacement Kits) Also be sure to check the white Delrin Bushings in the top and bottom of the Halyard Swivel. Make sure that they are firmly in place and that they fit tightly against the rod. If they are sufficiently worn they can allow the Halyard Swivel to cock to one side. This will increase the effort needed to furl. If these Bushings are missing then there will be metal on metal contact between the Halyard Swivel and the Luff Rod. This can cause damage by scoring the Luff Rod. In either case the Bushings will need to be replaced.
