Reef Hooks


Reef Hooks and Reef Hook/Tack Assemblies
Reef Hooks are used to hold down the "new" Tack (at the reef point) when jiffy reefing the Mainsail. Simple and Rams' Horn Reef Hooks are attached to the Boom, as near the Tack attachment as possible, and are either screwed to the Boom or are attached to the horizontal Gooseneck Pin. In many applications (where the attachment Bolt can not be tightened enough to hold the Reef Hook in place without causing the Gooseneck Toggle to bind) they are wholly unsuited to the task and are, at best, a marginal solution used only where no better off-the-shelf item is available.
Reef Hook/Tack Assemblies are a much better solution, generally attached beneath the head of the vertical Gooseneck Bolt, on which the Gooseneck Toggle pivots. These units keep the sail pivot point in line with the Boom pivot point, as well as keeping all Tacks (Original and Reefing) in close proximity, allowing for a better sail set. Please note: If using this item on a mast which has a vertical Gooseneck Pin, it must be replaced with a vertical Gooseneck Bolt and a Nut, as you will now have the full tension of the main halyard on it. A cotter pin is not strong enough to take this shear load. Some Reef Hook/Tack Assemblies are available already welded to a vertical Gooseneck Bolt, please specify the vertical outside measurement of your Gooseneck Bracket, and Pin diameter. All Mainsails should have 2 SS rings webbed together through each of the forward Reef Grommets, as this simplifies the Reefing procedure with all systems.
Cunningham Hooks are used on Mainsails and Jibs, frequently spliced to a line for remote convenience.

Rig-Rite stocks a large variety of Reef Hooks originally produced by many different Spar Builders. As always, there have been many 'specials' produced over the years, if no Reef Hook arrangement listed here is suitable for your application, please contact us with your requirements and complete dimensions.

Some Gooseneck Toggles have Reef Hooks incorporated into them. As these items are first and foremost Gooseneck Toggles, they are listed separately, See Gooseneck Toggles.

A variety of Gooseneck Tack Attachments (without Reef Hooks) for use with a Vertical Bolt, or including an integral Bolt are also available, and are listed separately, See: Gooseneck Tack Attachments.

Other specialized Reef Hook arrangements, specific to European Spar Builders, are also available.
Isomat Spars use a variety of specialized Reef Hooks, See Isomat Booms.
Z-Spar Spars use their own variety of specialized Reef Hooks, See Z-Spar Booms.
