Boom Gallows, new




Hardly ever seen these days, the traditional Boom Gallows(a device that contains the aft end of the boom when it is not utilized by the sail) has gone by the wayside. Bluewater boats normally consider this item an essential piece of gear but for some reason mine was missing although it was originally installed by CSY. The prior owners bought a monstrous traveler and Navetec Hydraulic Vang and removed the Gallows.

Well, the past owners are gone, the traveller is gone, a Garhauer rigid Vang is installed and new Boom Gallows is now receiving it's last coats of Cetol.

The gallows must have more needs than I know, but I feel it will help me control the boom in severe weather and lessen wearing of all boom componets caused by movement.

The traditional Boom Gallow's usually have short support struts on both port and starboard uprights-the pipe/tube that holds up each end of the wood framework. I chose not to have the support tubes where traditionally placed, one on each leg but rather a center main tube run forward in front of the companion way hatch cover. The Boom Gallows would set more like a TriPod.

The work is done. The design is different from tradition as it is a one piece stainless steel structure, with a teak covering.
CENTER PLANK WAS CUT FOR FINAL SHAPE AND INCLUDES SPACE FOR Stainless Steel of upper framework.

(Photos are included to show this different approach, which encapsulates the framework rather than the two legs bolted to a board.)

To do this, the center of the 3 boards, needs to be the same thickness as the stainless structure..in this case 1.25". Then, by a simple tracing, the wood is cut to the appropriate shape with allowances for the internal placement of the stainless tubing. When the S.S. frame, is encapsulated inside the center board and then the two outer boards, all but the finish work is done.

The following photos should explain. All stainless steel work was done at Gulf Coast Industrial Repair, in Gulfport, Florida. Rick Heim is a master of machine work and welding. We refer to his work, as "Rick's Art."
