Boom Bails

Boom Bails
Boom Bails are mounted to the Boom and are used to attach Blocks for the Mainsheet and Vang. For most applications Standard Pivoting Boom Bails, which attach with a single Bolt, are used. To select a Standard Bail you will need to know the maximum width of the Boom Section. On smaller boats, Standard and Small Boom Bails are frequently mounted to the Mast for attachment of a (soft) Boom Vang Block and Tackle. Pivoting (Standard) Boom Bails for attachment with a single Bolt. - Reinforcing Plates for Pivoting (Standard) Boom Bails for high-load applications. Small Boom Bails for attachment with screws or rivets. Internally Mounted Boom Bails for attachment with screws or rivets. Special Boom Bails for Round and other Specific Boom Sections. Track Mounted Boom Bails for Booms with an integral Bail track. Track Mounted Vang Lugs for Booms with an integral Bail track. Weld-in Boom Vang Lugs for Custom applications. Boom Vang Ball Attachment Plates for Small Boat removable Boom Vangs using a wire swage ball.

Reinforcing Plates for Standard Boom Bails Boom Bail Bearing Plates are used to reinforce the boom wall, spreading the load of a single bolt attachment out over a greater area and increasing the bearing surface by using additional fasteners. Used with Standard (Pivoting) Boom Bails, they reinforce this most highly loaded part of the Boom and are especially critical on bolts for Vang Bails. Please Note that the larger Reinforcing Plates can be used with Flange Bushings (and a smaller Bolt) to achieve the same strength with maximum weight reduction. In heavy-duty applications they are sometimes used with Compression Tubes.
